Why Analogue CCTV?

Digital CCTV is CCTV that takes advantage of modern digital technology to great effect and that has for many people largely replaced analogue CCTV. Essentially a digital security camera records onto files that are stored on a memory card, an internal storage device (within the security camera itself) or online. This then means that there is no need for large physical storage such as the VHS tapes used in analogue CCTV, and also means that more can be done with the data as it can be analysed and manipulated by computer.

These 'more things' incorporate a lot of great functions. For instance an IP CCTV camera can allow you to watch the footage remotely while VoIP can even allow you to then 'speak' through the security camera should anything appear to be wrong. Better yet is motion detection that means you can set cameras up to record only when they sense movement meaning that you don't have to watch hours of footage of an empty warehouse to see if anything of interest happened. Even more impressive is video analysis which can record only when there is movement that appears to be caused by human activity. This often works well enough that it can be safely linked to your alarm systems so that if the camera picks up movement it can alert you and anyone near. Again with VoIP it can even call you.

So the question is why would people still use analogue cameras? Just as there are many advantages to digital CCTV, there are many drawbacks to analogue - perhaps the most damning being that it can only record from one 'track' at a time meaning it can only record from one camera and could thus miss the important 'action'.

However there are actually several reasons for this, and though they are lower tech, analogue still has a lot of advantages that certain businesses and individuals can benefit from. The first of these is that the technology is simple to understand. For small private shops run by technophobes, installing lots of digital cameras could seem daunting and if anything went wrong they would not know what to do - not so with analogue. At the same time the analogue CCTV will less likely go wrong in the first place, as there is nothing to crash and no way for the data to get accidentally erased (short of a magnet on the VHS tape). Again this makes it much easier to handle for those who aren't that familiar with technology and also means in some ways analogue CCTV can be more reliable. A good idea for those companies with a great digital CCTV system is to get an analogue security camera is backup in case there is a power cut or something else that should cause the digital cameras to cut out.

Finally there is the matter of expense and of course being older, analogue cameras are much cheaper not only to purchase but also to install and to maintain.

Need a IP CCTV System

This article helps you to specify a CCTV system; the intended audience for this guide being either an installing company or an end user. You should be aware there are many types of CCTV systems available on the market; these range from cheap cctv systems for basic monitoring, best value security camera systems for some form of identification and to high resolution security systems that lead to identification and prosecution.

A good security camera system will offer best value for money without compromise on the quality. There are many products available on the market which makes it very difficult to identify what products are suitable for your requirement. Sometimes, it is equally difficult to identify areas that are vulnerable and a suitable cctv camera to target that area. Most people forget that a cctv camera system is a long term investment and they should discuss their requirements with a technical sales person before they make the purchase.

Understanding cctv terminology can also be daunting, see our FAQ section for more details.

Understanding your Security requirements

Main reasons for your requirement of cctv security cameras will reflect the type of system you need. Some of the reasons for needing a security system could be:

- Shop theft
- Shop or home break-ins
- Vandalism
- Industrial espionage
- Danger to individuals from attack.
- Health and safety of individuals on the premises or site.
- To replace or reduce manned guarding.
- To supplement manned guarding, making them more efficient.
- To monitor persons entering and leaving the premises.
- To provide visual confirmation of intruders activating an alarm.
- To monitor a remote, unattended site.
Reasons for a system could be endless, but for a particular site, there will finite reasons for considering CCTV. If they cannot be listed, you probably don-t need it.

What is the possible solution-

Once a problem is understood, the next step is to find how a solution can be achieved. The solution could be in many forms - it could be an intruder alarm system, some form of deterrent (lighting, fencing and gates), a cctv system or manned guarding. Your need will depend on the circumstances and requirements on any particular site, but it is important to at least make a list and consider all the possibilities. Some options maybe impracticable and others maybe too expensive but you should finish up with a short list of possibilities. Quite often, the solution will point to a cctv system as this will be cheaper and more affordable.

Decided that you need CCTV Systems-

Before selecting the type of cctv system that will fulfill your requirements, you should consider; the type of cctv cameras you need, how you will monitor the system, will you require network access (remote internet access) and cabling.

Type of cctv cameras you need:-

Colour cameras generally require a higher level of lighting than their Black & White counterparts do. Colour cameras give the advantage of being able to easily distinguish and detect objects simply by their colours where Black & White cameras offer better resolution in low light conditions.

- Covert cameras. These cameras are so small they cannot be easily seen or are disguised as a different device (such as smoke detector, PIR etc).
- Day/Night cameras. These cameras switch from colour to black and white depending on lighting levels. They are ideal for variable lighting conditions.
- Night Vision cameras. These cameras have their own light source in a light spectrum that can't be seen by the naked eye.
- Outdoor cameras. These cameras have hardened, waterproof outer bodies.
- Speed Dome cameras (Pan, Tilt, Zoom). These cameras allow for remote control of what the camera is pointed at and what it is focused on.
- Vandal Proof cameras. These cameras come in hardened cases that can resist physical abuse.

How you will monitor the cctv system-

- Main Output- Most CCTV DVRs have composite video output which can be viewed on standard TV Monitors (like AV input or SCART input)
- Spot out / Call output- This output is also composite Video which can be used to monitor cctv cameras in full screen mode in sequence.
- VGA output- this output is standard output used on PCs. Any VGA TFT LCD monitor can be used.

Network Access / Remote Access- CCTV DVR Access over the internet (broadband)

- Internet Access- Most CCTV DVRs now days have remote access via the internet
- Simplex- DVR can only perform either record or play back but cannot perform both simultaneously.
- Duplex- DVR can only perform two things simultaneously (record, play back or remote viwing but not all three simultaneously).
- Triplex- DVR will perform all three things simultaneously (record, play back and remote playback)
- Pentaplex - cctv DVR can carry record, playback, remote access, remote playback.

What type of cctv cables are there-

- Pre-made leads- these are pre-fabricated leads with BNC and power connectors already terminated on the cable. Very simple to install, no real skill required. These leads are design to carry low voltage (12V DC) upto a distance of around 35m. Distance greater than 35m will cause picture corruption with the camera.
- Local AC power - where the distance is greater than 35m, if cameras are powered locally, you can cover much greater distances. For distances upto 100m, RG59 coaxial cable could be used.
- Combined Coaxial cable with power- RG59 coaxial cable but 2 core power cable attached (like a Shotgun).
- CAT5E- Longer distances can be covered CAT5E in-conjunction with passive transceivers.

Selecting the most suitable cctv system is a compromise between the quality, area you want to cover and the overall budget. It is advisable that you have in-depth discussion with the technical sales person before you select the security cameras or the diy cctv system you need. A good technical person will try to understand your need, explain the difference between the various cctv cameras before any recommendation.

Cheap CCTV Cameras

Cheap CCTV cameras.

Cheap cameras come in many shapes and sizes so look out for the basic which are:

• Resolution of the camera. The most common types of cctv cameras are standard analogue type and nowadays they are 420-600 TV lines TVL. There are some cameras below and some above that TVL but not many. The higher the number the better the camera should be, but not always. I have taken many standard 420 line cameras and compared them to 600 line cameras and could not see the value in the 600 line, but that is not to say a 600 line camera is not better, just not always.
• Chipset used in the camera. The most common chips used are either Samsung or Sony and the extra lines are often just enhanced chips on steroids using similar base level image sensors, which explains why more lines is not always a guarantee of more quality. The rest of the cctv cameras often use generic electronics made by many manufacturers. Most cameras are made in China nowadays and it is rare to see a problem with that, although the cameras are still made in the USA, Taiwan, Japan, etc.
• Lens, lenses are critical to good image and many cameras that have a good chipset are let down by poor lens selection. The bigger the lens the better the image quality as a general rule because it allows more light and colours to enter the camera. A fixed lens is setup by a factory and cannot be changed, where as a vari-focal lens allow you to zoom in or out manually and then manually adjust the focus. An auto-iris lens is very handy and many vari-focal lenses have auto-iris features also. Auto-iris lenses need power from the camera to operate and simple open the lens more when it is darker, thus allowing more light and colours to enter and in reverse when too much light exists they will make the iris small and close much more light.
• Other things to look for include the housing and if it is weather and dust resistant or weather proof, although I do not like the terms weather proof, vandal proof, dust proof etc as I don;t believe anything can be entirely proofed.
• Night cameras can use technology that allow a much lower view in very low light and therefore have a LUX rating. the lower the LUX number the better the camera should see at night, so a 0.1 lux camera is not as good at night as a 0.01 lux camera would be.

Hope this all helps and happy sourcing and selecting Cheap CCTV cameras.

IP CCTV Cameras For Retailers

IP CCTV Cameras are making a significant impact on the cctv security systems among retailers. The need to keep premises and stock safely under a watchful eye makes the investment in a reliable CCTV security system a necessity for retailers.

But, there are a number of factors that need to be taken into account when making that investment, from the CCTV cameras purchased to other components that can affect the efficiency and reliability of the system overall.

It is possible to get everything necessary in one package, thanks to the range of CCTV kits that are available. Often, these kits are perfect for the needs of a small retailer. However, it is always beneficial to look at the alternatives, speak to expert security system providers and generally get an understanding of the relative issues. That is why we have listed two key factors that are worth careful consideration.

The most obvious CCTV security equipment issue is the type of camera to install. There is no shortage of different styles to choose from, from the traditional block shaped camera with protruding lens to the more subtle domed camera that can go almost unnoticed in a corner. However, style is one thing and capability is another. The three most common choices of camera are mono, colour and ip cameras. The mono camera is a basic black and white camera. The modern models do offer far better images that those of their predecessors, but a lack of colour can be a problem in some situations. Unsurprisingly then, colour is a popular option, providing crisp imaging that makes subject recognition easier.

Given the internet age that we live in, ip cameras have grown much more popular in recent years. These allow images to be sent over the internet directly, in the same way that webcams do. However, the crucial difference is that ip cameras are built for security surveillance purposes, and are much more durable and longer lasting. These cameras also have an inbuilt recording facility, so images can be uploaded directly without the need of a recorder, and can also be transfered onto USB sticks and SD cards with ease. However, that is not to say that recorder is not still necessary. In fact, they are the second chief concern for retailers to consider. Today, the digital video recorder, more commonly known as simply DVRs, are the most common method of recording video surveillance footage. Their great advantage is that the image quality is far greater than it was with the older analogue recorders. They also feature a range of capabilities that the older systems could never offer, such as detailed close ups on recorded images, which should not be confused with a camera zooming in while recording.

DVRs also accommodate a lot more cameras than the older systems, with images from as many as 64 cameras being recorded and stored. However, most of these digital recorders are not actually wireless, which means that cameras need to be sited close to the DVR and connected directly to it by cable. For a small retail shop, this provides no great problem, since every camera will be in close proximity to the recorder anyway, but for larger businesses, this could be a problem. The best alternative to a DVR is an NVR, otherwise known as a network video recorder.

The main difference between them is that numerous ip cameras can be used with NVRs, meaning their images can be received from the other side of the world. Images are available in high definition, while operational aspects such as an image search, a simple four step set up and convenient image transfers makes NVRs much easier to use. In any security system, there is an array of equipment required. The secret is to identify what is actually necessary before going out to buy security system or CCTV kits, or individual system components. Clearly, the most essential part of a CCTV security system are the CCTV cameras themselves, making them the starting point for any investment considerations. However, it is worth noting that there is more CCTV security equipment to consider, such as the digital or network video recorders, the number of cameras and technology they require to make them completely effective.

Iain Jenkins writes articles for Traders Warehouse, who have a wide range of CCTV security equipment, fire alarms and access control items. Security in many organisations is one of the most important factors, and Traders' cctv kits containing dvd writers and dvrs, cable leads, warning signs and a varying number of cctv cameras depending on the size of the kit. The cameras are available either as standard fixed or as ceiling mountable vandal resistsant dome

Diagnosing CCTV Video Signal Problems

Lost your video signal from one of your security cameras? Maybe you have a fuzzy picture or rolling video. Whatever the problem may be with your video signal; there are a few tips and steps you can take to attempt to diagnose the issue.

Check The Cable

If you are able, it can be beneficial to quickly take a secondary cctv cable and connect it to your security camera to see if your cable is the problem. Even if this solves the issue; it may not be the problem if you're transmitting your video signal over a long cable run, as we will discuss next.

Not Enough Power

If you are running your video signal over long cctv cable runs; then they may begin to build up a resistance in the line and degrade your video signal. If you are using a 12VDC power source; then one solution would be to switch to a 24VAC power source with a high enough amperage; then all you would need to do is equip a 24VAC to 12VDC converter at the end of the line before hooking it into your security camera.

This solution would sufficiently boost the power on your cable to provide a better connection and signal grade. On the other hand a cctv power booster may be enough to do the trick depending on the length of your run.

Ground Loop Isolator

A quick and relatively cheap fix for rolling video or fuzzy signal can be what is called a ground loop isolator. By using this device between the end of your security camera cable and your DVR you can sometimes eliminate these problems.

In essence what the isolator does is help to "isolate" your video signal and remove/shield it from various unforeseen electrical interferences and signal degradations.

Check Your Crimps & Connectors

If you have a loose or badly crimped cctv connector on one of your cables; you may be losing or degrading your video signal at this point. Try replacing or tightening these connectors and see if this solves the problem. Furthermore crimped cctv ends tend to last longer and have a better signal then screw on ones.

Check Your Lens & On-Camera Connections

A couple simple things you can test is your on-camera connections and your cctv lens. Make sure all of your connections are secure and not loose, and make sure that your lens is properly tightened and in focus.

Additionally if you find or have a strong feeling that your cctv cable is at fault; then you should check the run and make sure there are no breaks or nicks in the line. Sometimes this type of fault can be solved by simply tightening some good electrical tape around the problem area.

CCTV Security Systems

Closed-circuit television is a kind of a security technique which involves the usages of video camera which are commonly called CCTV cameras. The purposes of these are to transmit a signal to TV sets or monitors for the purpose of security. CCTV is a lot different than broadcast television. It differs in that the signal is not openly transmitted.

CCTV systems employ point to point wireless links, often used for surveillance. These Camera security systems are used in areas which need security. Some examples can be banks, casinos, airports, shopping malls or military installations, army bases etc. However, the increased use of CCTV in public places has caused debate over public. It is argued that this is a debate on security versus privacy. In many industries and industrial plants and semi-industrial plants, these cameras are used to observe parts of processes that are remote. The control is through a control room. Continuous operation of CCTV systems could be done. They can also be used to overview just a specific portion or an area.
The first CCTV system was installed at Test Stand VII. It was in Peenemünde in the country of Germany in the year 1942.

These CCTV cameras were installed for observing the launch and take off of V2 rockets. CCTV systems are often used at launch. They are used at these sites to record the flight of the rockets. This is helpful in order to find the possible causes of malfunctions if any, happening during the launch. Film cameras are also used for this purpose. The more large rockets are often installed with camera systems. They allow pictures of stage separation to be transmitted back to earth by radio linkages. CCTV systems are also used to observe the launch pad, before the launch. This is none especially when no other person can be there, because of safety hazards and other safety reasons.
The industrial process nowadays is mostly supervised by security cameras. There are some processes which are harmful for the humans but still take place.These cameras are mainly used in chemical industies.The other processes include the interior of reactors, facilities for manufacture of nuclear fuel etc. Use of Thermo graphic Cameras are used which permit operators to measure the temperature of the processes also.

The usage of of these systems in such processes is sometimes made mandatory by law.
CCTV cameras are also used outside government offices and other special government facilities. CCTV systems are a very good means of increasing security in banks. CCTV today has developed to that point where it is very simple and inexpensive enough to be used as home security systems also.
CCTV security systems are the next big thing on the general security scene, they have already overtaken all other means of security including spy cameras. CCTV cameras are and will continue to develop into the greatest security solutions available worldwide. CCTV security systems, CCTV security solutions would be buzz words in deciding about even security of small and very tiny enterprises. After all, with prices falling everyday, CCTV is much more affordable today than it was earlier.

CCTV Security Systems Going Forward

CCTV, or closed-circuit television, has been a mainstay of security systems for decades. However, today's CCTV security systems have significant advantages as compared to previous years. As technology improves, so, too, does CCTV's capabilities.

IP video security

Today's security systems utilize CCTV security cameras that utilize Internet protocol technologies. IP CCTV video security systems have better resolution than traditional analog systems do, more flexible installation, and easier to use features.

Marry analog technology and CCTV security systems' technology

It can be expensive to completely replace old analog CCTV systems with new IP-based ones, but fortunately, you don't have to. You can integrate analog systems with new IP technology by utilizing a hybrid platform. This gives you all of the benefits of the newer technology and is a more cost effective option as compared to completely "starting over" with new equipment.

Advantages of CCTV security systems technology

Whether you decide to completely replace your old analog CCTV systems with new completely IP-based CCTV systems or simply do an integration of old and new technology, you'll find significant advantages:

· Inexpensive, easy to set up and maintain

Today, it's easy to buy and set up CCTV security cameras and related systems, and very easy to maintain, as well. Because today's CCTV security systems are digital in nature, they're much easier to manage. The information received from them is much more easily stored, and much less corruptible. Information is recorded on a DVR recorder with CCTV security cameras, instead of on tapes that can be easily damaged. You can also download the information from the recorder to a computer, and if you need to save the data long-term, you can burn it to a CD.

While technology for analog TGV security systems remained relatively high-priced and the recording equipment bulky and hard to manage, today's CCTV cameras and other equipment have shrunk in size and price while expanding in capability, meaning that you can have very sophisticated equipment at a very modest price. Although you may want cameras clearly in view for security reasons, the cameras themselves are also very small, meaning that they can be placed just about anywhere for complete coverage.

· Continuous recording from all cameras

While older analog systems that used tape generally only did time lapse recording, newer CCTV security cameras can record continuously, and the information can be captured and saved from all cameras. This allows business owners, for example, to track data from all sources and to keep historical records; analog tapes, by contrast, were usually ultimately taped over, sometimes causing loss of valuable information.

· Customizable

Because today's CCTV security systems and CCTV security cameras can be bought in in an endless variety of configurations, sizes, and functions, you can choose your system based on your needs. In addition, as your business grows, it's easy to expand your system for more coverage as you need it. And because this technology is so inexpensive, you can grow your system as you need to, without the worries about expense, flexibility, or storage space traditional systems might give you.

CCTV Terminology

If you run a business that has its own premises then making sure that you have some form of CCTV in place is a necessity. This will help you in many ways to protect your business from theft or vandalism acting as both a deterrent and as an early warning system and a way of aiding the police in their investigation and providing evidence in court. If you have CCTV in your building them you can prevent the majority of criminals from trying to break in, catch the majority that do red handed and track down any in the slight chance that they get through.

However going about installing CCTV can be quite tricky for those new to the subject when so few people understand all of the different terminology and jargon surrounding the subject. There are a vast range of different CCTV systems and knowing which is which and what you need to look out for can be complicated. To make matters a little easier, here is a guide to just some of the terms.

CCTV: CCTV itself stands for 'Closed Circuit Television' - in other words it means that you have video footage that is not designed to be broadcast but that remains withing the 'closed circuit' of your building. Today that circuit is more a metaphor as some footage is now streamed.

Analogue CCTV: Analogue is the opposite to digital - in other words it doesn't use a computer or programming or electrical signals in the same way that say digital TV or digital radio does. This is an outmoded form of CCTV that only has limited uses today.

Digital CCTV: This is more like it - this is what most modern and serious organizations will use in order to protect their company and it creates data that can be saved on a computer or memory card or which can be streamed live.

IP CCTV: IP CCTV stands for 'internet protocol'. It means that the footage is sent wirelessly to be picked up by another computer or saved at a remote server. This also means that you have no wires for your IP CCTV and that means that you are less restricted with where you can place your cameras and you will be able to move the cameras with ease when necessary (due to a redecoration for instance).

Wireless CCTV: Wireless CCTV is any form of CCTV that has no wires - such as IP CCTV.

VoIP CCTV: This stands for 'Voice IP CCTV' and essentially means that you have a camera that doesn't only film footage but also sound. That then means that you can listen to what is happening on your premises, and it means that you can broadcast your own voice to ask people on-site for status reports etc.

Video Analysis: Video analysis means that your footage can be analyzed by a computer in order to look out for things that are out of the ordinary or alarming. For instance video analysis might sound an alarm if it sees movement that appears human in nature.

There are lots of types of CCTV such as IP CCTV. For more details visit the hyperlinks.

Chosing A CCTV System Installer

Digital CCTV surveillance systems are very common in any organization, business institution and even residential homes these days. It's become very common in many houses also now as the number of robberies and other crimes are increasing by leaps and bounds day in and day out. The benefit of a CCTV is far more in comparison to its cost.

So once you have decided to install a CCTV in your home or office, you need to work out your budget, but I would like to brief you a little on the latest CCTV before that. The latest of all in a CCTV is the IP camera. An IP camera not only performs the function of a camera, but is a web server and a computer processor too. It offers many advantages as compared to a traditional analog camera. These are the words of a professional CCTV installer "An IP camera is any day better than an analog camera", but of course money is the main criteria in any sphere of life because without budgeting nothing can move forward, be it business or a home.

No home, organization or institution can survive if its expenditure is more than its income, this goes without saying, unlike charitable institutions. In my words an IP camera is the best and if you can afford it. It's better because it has more flexibility, better resolution and high quality images. The other benefit again in the words of a CCTV installer is that it can be used to email video images to anybody, which is of great advantage in bigger organizations or firms.

The best bet to look out for a CCTV installer in your area is the internet. If you are not satisfied or happy with the internet search results, the next bet will be to ask your relatives or friends in the neighbourhood. You can also check out your Yellow Pages to find a suitable CCTV installer.

The benefits of hiring a CCTV installer is that they take the entire responsibility of coming and surveying the place where you want to install your CCTV, brief you on the different products available and provide you with after sales services. There is no harm in installing the CCTV yourself if you are confident of it, but the disadvantage is that you won't get any after sales service.

The number of CCTV installers in the market is very high, but what you shouldn't forget is that a reputable CCTV installer should at least be offering to make arrangements for repairs of your CCTV in the future and should provide a CCTV maintenance contract.

CCTV-PTZ Camera Innovation

A CCTV is a common device used for surveillance these days. CCTV stands for Closed circuit television and a PTZ camera is a new innovation in it. As you might very well know that a camera is used in the function of a CCTV, PTZ is the camera used in the latest CCTVs.

PTZ stands for Pan Tilt Zoom camera. A Pan tilt zoom camera is a CCTV camera , which has zoom control as well as it can be controlled with a remote. These cameras can be used manually as well as with the help of a remote. Having a CCTV with this kind of camera enables it to capture high quality videos for a longer period of time than CCTVs with other kinds of cameras. PTZ cameras also reduce storage costs and bandwidth significantly.

This camera can make a 360 degree sweep of the environment. It also helps to zoom in on objects you want to focus on specifically. It's called pan tilt because this camera has the ability to tilt up and down and turn itself in a complete circle too, so basically no nook and corner will be left without surveillance with these kinds of cameras installed.

Remote computer systems in a CCTV using these kinds of cameras, which is configured to move the camera in a particular pattern or to maneuver it manually as you wish. Computers' work on the brains of a human, so you got to program the computer as per your want, like the degree at which the camera should be rotating and the angle at which it should be doing it.

These cameras are usually sphere shaped for its easy functioning as its main speciality is it's completely mobile. There are different types available in these kinds of cameras too. Some are high definition ones, allowing to record detailed images.

Some PTZ cameras have tinted shielding to hide it from the common man's glare. Some of them also have maintenance mechanisms and internal heating system, which enables it to keep running smoothly.

These cameras should put you at ease with regards to surveillance as it requires little attention and low maintenance. Of course malfunction may result in extra repair costs and regular cleaning is required as in the case of any camera. The use of these kind of cameras in more prominent in the military, law enforcement agencies and high profile businesses like the jewellery industry etc.

CCTV Camera Systems

Closed circuit television, or otherwise known as CCTV camera systems, can be seen at present in many shops, stadiums, train stations, offices and even homes and other private venues. A security camera is usually installed in an area to improve the safety of the people by preventing crime or to monitor what happens there. Many people and organisations around the world have learned to take advantage of a CCTV kit and employed it use for various purposes, including research. In fact, it has been decades since men discovered and experienced the benefits of having one. For those who are curious about the history and origin of these monitoring devices, read on.

1940s

Back in 1942, surveillance equipment was used to monitor the taking off of rockets and missiles in Germany, which is primarily a military activity. A well-known German engineer designed the device, backed by Siemens AG. The activity was mainly intended for testing, but at present, rocket and space ship launch sites across the world are still installed with monitoring devices so as to help identify areas for improvement and for further sophisticated research. This is highly important, as scientists or engineers could not get too close to any launch site because of the dangers that it imposes to their health. It was in 1949 when CCTV cameras became commercially available in America from a company named Vericon, an organization known to be a contractor for the government.

1950s to 1960s

The dawn of CCTV systems in the United Kingdom began in 1953 during the coronation of the Queen, a prestigious event and one that put a great mark in the history of Britain. Around the 1960s, Metropolitan Police began to use these surveillance devices as a tool to observe people during rallies or events where the Prime Minister or any member of the Royal Family would appear. It was also during this time when video cameras were installed permanently at a number of streets in London and several more counties in England started experimenting with installation of surveillance devices at city centers. Even the British Railways realised the advantage of putting cameras after a part of the tracks was vandalised. New York in America also started to put circuit television in their streets around this time. Since then, countries across Europe and America began to employ this equipment in various ways.

1970s and 1980s

The use of security cameras continued to rise in popularity during the 1970s up to the 1980s. Major roads in London as well as some of the London Underground Stations began to be monitored during the early to mid 70s. They also started installing CCTV security systems at the soccer match venues. During the late 80s, surveillance systems were installed at parking garages and council estates that the local authorities were running. This was not only used to watch the vehicles on the streets, but also to monitor the main rallying venues used for public protest in London.

1990s to Present

At this time, national roads in Britain employed the use of speed cameras so as to keep track of those people driving beyond the speed limit, or those beating the red light. It was a milestone, which made a big difference in traffic enforcement using CCTV systems. Automatic teller machines were also installed with monitoring equipment to prevent theft and other crimes as people use the machines. The government of different countries saw the importance of these devices and allocated budget for the installation and maintenance of these systems on a large scale, forming an important part of their crime prevention efforts. At present, there are over 2.5 million security cameras in United Kingdom alone in order to prevent and detect the occurrence of crime.

Countless people and organizations, both private and public, have enjoyed the advantages of having CCTV camera systems. It has been used in and outside of homes and offices for purposes that range from capturing thieves to catching an unfaithful wife or husband. Businesses use a CCTV kit both in their offices and shops to scare off shoplifters and to protect their employees. Schools, banks, resorts and churches use security cameras in order to watch for the safety of the bulk of people that go in and out of these institutions.

Iain Jenkins writes articles for CCTV Direct, who supply and sell CCTV camera systems including security lighting, monitors and alarms. For any business, having a security camera in rooms around the premises is important to prevent theft, damage or entry by unwanted intruders. By using a full CCTV kit, a business will not only have cameras but other essential accessories including monitors, recording equipment, cabling and brackets to mount the cameras as required.

Mobile CCTV

The use of Mobile CCTV is growing across industrial vehicles and applications. These cctv systems help to protect vehicles whilst on the road, when the vehicles are busy at work or when vehicles are inactive and for example parked up. This technology provides increased security and safety, which is essential for fleet vehicles and can help to dramatically reduce total fleet costs. Furthermore, fleet and industrial vehicles are on the road for extended periods and are therefore more likely to be involved in road accidents than, for example a domestic road vehicle. There are many examples and applications where Mobile CCTV can be effective.

Examples of where Mobile CCTV can be effective:

- Fleet Vehicles

- Haulage Vehicles

- Taxis and Private Hire Vehicles

- Plant Machinery

- Buses

- Trains

- Trams

Depending on the configuration of the mobile CCTV system and vehicle cameras it is possible to monitor the road ahead, the inside of the cabin (with driver), the loading bays and the rear of the vehicle. These camera locations can help to monitor staff, to protect the vehicles whilst driving and also help to prevent theft of tools and goods. Other options available with these systems include live video transmission, GPS tracking, geo-fencing and more! These features demonstrate how versatile CCTV systems can be in helping to enhance vehicle and fleet safety and to ultimately reduce fleet costs.

For fleet managers live mobile CCTV can be used to pinpoint where their drivers are and to monitor what is going on both inside and outside of the fleet vehicles. Essential information is also captured in the event of an accident, such as, vehicle speed, vehicle location, sudden impacts to the vehicle and the time and date of recordings are often embedded into files. When this information is sent live via 3G it enables fleet managers to act immediately and can also help to prevent from false claims being made against the fleet. This information can also be used for staff training and development purposes, to monitor driver behavior and to improve fleet fuel efficiency.

There are a range of mobile CCTV systems available online. However, it is important to find a system that adequately fits the requirements of your fleet. Systems can be tailored to suit your requirements, a process that considers your vehicle type, the location you wish to have the cameras in and the requirements of the system.

VM-417 Diagnostic CCTV Meter

For surveillance installers a Difinitron VM-417 can at times be a very powerful tool in their arsenal for diagnosing video signal problems in a customers surveillance system.

What Is The VM-417

A VM-417 is a video test meter that allows an installer to test a CCTV cable line and make sure that certain levels are within their operating range. This meter tests to make sure that your sync, composite video, luminance, and color burst levels are all within operating ranges; as well as being able to help adjust your focus.

Furthermore the VM-417 is manufactured by Difinitron and it is made in the USA.

What Each Measurement Corresponds To

1. Sync Level Measures the amplitude of the video synchronizing pulse.
2. Video Level Measures the overall amplitude to determine Peak to Peak level.
3. Luminance Measures the white level of video.
4. Color Burst Measures the color burst amplitude of a color camera.
5. Focus is the maximum reading that corresponds to the most accurate focus.

Example Of Use

A great use for this meter can be to measure your video levels on a surveillance system that is using a video distribution amplifier. The reason for this is that if you find yourself trying to troubleshoot a surveillance system that has a faulty signal or no signal at all, and it is using one of these; the problem may lie within the level adjustments of the distributor.

A lot of video distribution amplifiers have their own adjustable levels for sharpness, brightness, etc... and if these levels are out of whack, then it can cause a failure. A quick way to test this is by testing your video levels before it reaches the amplifier, and then after it leaves the amplifier. If the levels are fine going in, but they are off when they come out; then your problem lies in the distribution module.

At this point it is a simple matter of fine tuning the adjustments on the distributor until the levels reach an acceptable range.

Now this fine tuning of the amplifier can be done without using a VM-417 test meter to confirm the diagnosis, but it will be a lot trickier as you wont know what levels are currently out of whack, and it will be a total "guess and test" in changing the adjustments.

Made For Installers

The VM-417 CCTV meter is a very impressive tool for diagnosing surveillance systems; however it is definitely designed for an installer and surveillance system designer to use. The reason being that it generally prices around $600, and this is not a cost effective solution to buy for use by a single end user.

VM-417 Optional Equipment

The VM-417 has an optional protective case for use in more hazardous environments. The OBC-12 is a highly visible orange case that is made for the VM-417 and it is made of a highly durable rubber. Furthermore this case can even accommodate other CCTV test meters.

Installing CCTV In Your Home

Over the years, a lot of people have taken advantage of having a CCTV camera right at their homes, businesses and workplace. Even law authorities have realised the need to have CCTV monitors in helping them solve and prevent crime. The situation at present requires families to guard the safety and security of their own homes more than ever. It is no longer enough to simply lock the doors just to keep anyone from breaking in to our homes, and having a DVR to capture any unlikely events can provide more security for the family. Read on to find out about the top reasons why it is very important to install a CCTV at home.

It Wards Off Intruders and Burglars

Having surveillance devices certainly help deter burglars from breaking into homes. Even statistics dictate that thieves will think twice about committing the crime if they see any surveillance equipment installed in and around the vicinity. They would rather go somewhere else where there is less likelihood that they will be caught. Believe it or not, a criminal would still rather go for the easier catch and would avoid a home that has increased security, as that would give them a hard time. In case that any intruder still breaks in to a house, the recorded videos from a security camera can help identify the person. The videos can be used as evidence against a person who committed any crime.

It Ensures the Safety of Children at Home

Aside from preventing intruders from getting close to any property, parents can also use CCTV cameras to watch their kids while they are away at work or travel. A lot of parents discovered the advantages of having this at home and installed devices in areas where their children often play like the pool area, backyard or the living room. This way, they can monitor the activities of the kids and find out right away if they are doing anything harmful that can hurt themselves or each other. The security system can also be used to make sure that the babysitter or nanny, as well as the repairman that was possibly hired for the day, does not steal anything from the house or worse, do anything to hurt the kids and compromise the security and safety of the residence in general.

It Can Possibly Reduce Insurance Premiums

Because of the increased security in and around the home, some people may even enjoy a discount from their home insurance companies. These companies like it if there is lesser chance that a home will be burgled, as it also means that there is a smaller possibility that the homeowner will file a claim. The decreased insurance premiums can reduce the expenses that a family must have already tons of, making a CCTV camera an extremely good investment to have nowadays.

It Allows Homeowners To Watch Their Property While They Are Away

Individuals who go away for travel or work can still watch over their homes because of a camera system. The advancements and innovations in technology now allow anyone to view feeds from a digital video recorder installed at home. Through the use of Internet, an individual can easily check what's going on at his or her property even whilst traveling. Most CCTV kits provide access to a webpage where a user can stream videos from the camera, giving anyone the peace of mind. Some people go back from a holiday, work or shopping only to find a broken antique vase in their living rooms. Having a monitoring system will allow the homeowner to find out who is responsible for events such as this.

The safety of homes and families is of utmost importance to everyone. Investing in a cctv to place at home will be a great way to protect family members and material possessions that are supposedly safe at home. The crimes rates at present make it almost necessary for everyone to employ a dvr in order to scare away criminals or to help catch them. The cctv monitors are more than just the usual equipment we see at various establishments across the country. They can also be a part of our daily lives a home.

CCTV Camera Systems

Whenever I am asked to review some CCTV system footage to help identify the activity and people in the footage, I begin by creating a camera grid. A CCTV camera grid is a layout of all closed circuit cameras with their location and proximity to the activity and people in the recording.

There are several types of CCTV cameras, one of which is a point tilt zoom camera. These PTZ cameras are made to follow the action as directed by their security (or loss prevention) operators.

In one case I was asked to review several cameras from a department store that covered a shop lifter. Several of the cameras were a type of extremely high quality PTZ camera and actually followed the suspect around the store. Since the CCTV system was digital, the footage looked amazing and needed very little clarification.

Although the footage was great, we did need a camera grid. Working for the defense in this case, we had a series of events to determine that would help negotiate a plea. I set off to draw the store layout on a piece of paper and to number the cameras as I went along the layout. We were able to determine which cameras were in what area of the store so when the suspect passed through those areas a second time, we knew to look at the previous cameras for any other activity that could be seen outside of the main coverage area.

Then two great breaks came when we found camera shots in unlikely places. The camera shots showed us a series of events as they actually occurred on other cameras in addition to the coverage of the main camera in that specific coverage area.

As you can see from my experience, by starting your video forensic examination with a camera grid, you can discover a lot more about your CCTV video footage than by simply relying on the obvious cameras for each series of events.

Lastly, keep in mind that nearby businesses like convenience stores and gas stations have exterior CCTV systems that may have video recordings that can help your case. A video forensic expert can enlarge and clarify distant footage that might help add evidence to support your case. Remember, it's about the preponderance of the evidence. In any case, all we have to do is tip the scale slightly to address and establish a reasonable doubt.

CCTV Explained

CCTV is an abbreviation for Closed Circuit Television. CCTV systems simply mean video cameras are used to transmit signals to a few monitors located in a control room. These cctv video cameras systems are generally used for security purposes like in banks, malls, military, airports etc.

In industrial sectors, sometimes where humans can't go into a particular room because of its high or low temperature or maybe due to any other reason, CCTVs turn out to be helpful because you can observe the room through the camera, even if you personally can't get into the room or so. These cameras can be made to work continuously or only at particular point of time when you want it to. Nowadays CCTVs use digital video recording (DVR) features in its latest models, which was advancement in this field. Its quality is better and there are less chances of this one getting spoiled when you require it the most. It also has additional features like email alerts and motion detection. Now there are megapixels sensors available, which can support recording that can be send to network attached storage devices.

The first CCTV was devised in the year 1942 in Peenemunde, Germany by the company called Siemens. It was devised for the very first time to observe the launch of V2 rockets. A German scientist called Walter Bruch made and installed it for the very first time.

CCTVS are also used in subways in certain countries to ensure that everybody is indoors while the train takes off or while moving too. The use of CCTVs is unlimited for surveillance purposes, sometimes it is for security and sometimes in the case of a rocket it is to observe the surrounding. In certain cases human are unable to go, in these cases CCTVs come handy. Many culprits have been caught with the help of CCTVS like in major national events like bomb blasts, plane hijacking etc. Nowadays people even install it in their homes, so that they can monitor each and every movement of their children in their absence too. So in short it is good to install a CCTV camera if you are in earnest need of security. But you need to take care about your cctv installer

Discover About the Lux Rating and IP Worth

This rating can be seen on the box of camera kits that are for sale in the industry. It determines the sensitivity of the cctv camera in relation to shooting videos in locations and places where there is quite poor lighting. A rating that is close to zero means that the camera could be applied for monitoring an location each throughout the daytime when there's adequate light, and nighttime when there's possibly none. For capturing videos or images even when there's no light present at all, the advised rating is about 0.0001. A camera with a rating of 1 can still capture images even if the moon will be the only source of light. Getting in a position to identify the lux ratings will help buyers choose the appropriate kit for their small business or house.
