Home security is one of the growing security concerns in Britain today. Statistics show that in the UK every 37 seconds one home is burgled. Protecting and safeguarding homes and other properties has become a priority and Closed Circuit Televisions or CCTVs are popular equipment employed for this purpose.
CCTV is a visual surveillance technology used to monitor residential, commercial as well as public properties. It is a network of linked cameras that produce viewable and recordable images. CCTVs usually form a part of the entire security system. These cameras can be interfaced with an alarm system i.e. the cameras can start recording when an alarm is triggered or they can relay the images to a monitoring facility. Here, an observer sounds an alarm when they notice any unusual activity. Nowadays, wireless CCTVs systems that work on battery operated panels and existing radio frequencies are gaining popularity as they do away with complex wiring systems and they are also easier to operate and maintain. These also allow for more flexibility and mobility, as it is easier to install wireless cameras, even in the most inaccessible areas.
CCTVs also allow remote monitoring i.e. you can monitor your home when you are away or on vacation. To view real time images of what is happening back home, you need to type in the URL of your wireless camera server from any browser. You can see these images just as easily on your mobile phone. Security companies also provide monitoring services that monitor the premises for you.
With advances in technology, these CCTVs now provide sophisticated features such as infrared night vision to capture images even in low light and night. They also come equipped with PIR (Passive Infrared) motion detection facilities, full pan, zoom, and tilt and audio mechanisms. PTZ (Pan Tilt Zoom) cameras are used for their increased performance, as they are able to rotate horizontally through 3600, vertically through 900 and have electrically powered zoom lenses capable of giving more than fifteen times the current optical zoom.
There are also a number of miniature or covert CCTV cameras available in the market. These CCTV cameras are very tiny or very cleverly disguised as smoke detectors, lamps, books, vcrs etc. to facilitate covert surveillance. Easy to spot CCTV cameras prove effective deterrents for offenders but these cameras are equally vulnerable to tampering and damage by the offender. These hidden or mini CCTVs provide that extra measure of security to your property and home.
Besides the obvious advantage of keeping an eye on your home and valuables in your absence, and thus safeguarding it, CCTVs have also increased the rate of conviction by helping detect crimes. These cameras provide the visual evidence of the offender’s crimes. Once people know they have been videotaped, they admit to the offense immediately. Such benefits, advance technology and easy availability make CCTVs the most widely used and relied upon security measure used in not only homes but also banks, offices, hospitals and other commercial enterprises.
