CCTV: You Are Being Watched, No Matter Where You Are
Closed circuit TV, CCTV, doesn’t require an introduction at all. The purpose of installing wired or wireless CCTV is fundamentally the one of surveillance and vigilance. These are bigger in size than the wearable spy cameras or hidden cameras and so leave that for the detectives for the moment. (Also what we are not considering now is the Chinese TV channel: CCTV.)
It is thanks to IRA, the Irish Republican Army, for having paved the way for developing the concept of CCTV, albeit in a tragic way. The Royal British Army, in response to the IRA bombings has experimented using CCTV for years, including outdoors, since 1970s through to 1990s. Although exact numbers can not known, an estimate tells us that there are much more than 400,000 surveillance cameras on London streets alone.
Is It Just Military Surveillance With CCTV?
CCTV is extensively being used in security system of industries, banks, super markets homes and all such places which are perceived as strategically and financially important. Commercial establishments using CCTV have increased manifolds in UK although it is not so common in US as it is perceived as a privacy threat. New York City has about 4000 CCTV installations and most of which are in shopping malls and other public places such as Liberty Statue, Lincoln Express, British Parliament, and places of strategic importance. Traffic monitoring and prosecution & crime detection have leapfrogged with the advent of CCTV.
After All, Just What Is This CCTV
Well, CCTV is a closed network of small surveillance TV cameras which telecast and/or record anything in their field of view. CCTV networks are usually wired together and finally connected to one or more monitors. There will be more monitors depending on the importance of surveillance the cost factors. If you have lesser monitors than the number of cameras, they can be switched in a sequence onto monitor/s. CCTV cameras have capabilities to either record hours of footage they filmed or telecast in a short range at a particularly dedicated frequency which can’t be intercepted by normal TVs.
After the tragic bombings in London Metro tubes last July, there has been an increased public demand for using DVR (digital video recording) cameras rather than traditional cameras with tapes. If you wonder how this would have helped the cause, take it here. Tapes were removed in the fortnight following the bombings for study, and follow-up attacks could not be recorded as a result.
Thinking of CCTV installation at your office? Take professional help and consult police if necessary. Some cameras can be hampered with or can be intercepted with cheap receivers. A complete installation won’t cost more than $4000, which is nothing when security is uppermost.
CCTV Cameras—Reduce the Risk of Crime
CCTV Cameras are among the most effective ways to reduce crime in your business or home, and there are a number of places to purchase CCTV equipment, even if you’re on a budget. Here are some things to look for when you’re shopping for CCTV cameras that will help you save time and money, as well as help you to better to protect your property.
First of all, you need to choose a CCTV camera that has both a wide range and a quality lens, so that you can see what’s going on no matter which part of the property you’re on, and you’ll be able to spot any suspicious people or activity right away.
Next, make sure that your CCTV camera is compact and is easily rotated. This way, the camera is not easily seen by intruders or customers, and the ability for the camera to rotate quickly and effectively will give you a total view of who comes in and out of your business or home. The Voltek Wireless CCTV camera is a great choice for this reason, and we also offer a number of great new product to compliment this camera.
It’s also a good idea to make sure that the CCTV equipment you purchase works well with the way that your property is set up in terms of how many enclosed walkways there are, whether or not there are open spaces throughout the office space or home, and how many rooms are usually occupied on the property. This will help you to determine how large of a camera you should purchase, and you may also want to purchase wireless CCTV equipment to eliminate the look of cables and plugs across the walls of your property.
Other equipment you’ll want to purchase in addition to the actual CCTV camera include a sign that you can post in front of your door or window on your property, which will let both potential criminals and customers know that the property is under surveillance. You’ll also want to make sure that you have a CCTV monitor that is hooked up to the camera, so that you can make sure that your property is safe, no matter where you are in your home or office. The monitors are available in both color and black and white, so you have the option of purchasing the monitors that are most affordable for you. If you’re just starting your business, or are switching alarm systems or moving into a new home or business building, you may also want to look into purchasing a dummy camera for a short period of time. The dummy cameras look very realistic, and you can use it to give the illusion of security on your property until you install a new CCTV camera. You may also want to look into the audio cameras we have to offer, such as the new Wireless Microcam Audio CCTV camera, so that you can hear what’s going on in your property as well as see it.
The shape of your camera will also play a big part in how well hidden the camera is, and how secure you can keep your home or business. Many times, if a surveillance camera is very obvious or large, criminals will immediately try to destroy the camera before stealing merchandise or money, or otherwise damaging the property. If a CCTV camera is well hidden, it will be difficult for burglars to find the camera, and it is much more likely that you will catch the trespassing on tape accurately. A discreet camera will also make customers or others in your home feel safer. So, small cameras, dome-shaped cameras, and even submergible cameras are a good idea if you want to add a little extra security to your home or business.
