CCTV Surveillance System

Home owners now have access to security systems that were previously only used by governments and large businesses. One of the most popular of these is the CCTV surveillance system. Closed-circuit television (CCTV) has been around for ages and has proven to be an effective means of monitoring and security. Closed-circuit simply means that the video cannot be accessed by outsiders. There are literally millions of these systems in use around the world. They can be found in office buildings, shopping malls, railway stations, airports, public spaces, and many other locations. Choosing the right CCTV surveillance system for the home is not as easy as it may seem. The cameras, recorder, monitor, and other components all need to work together for the system to be effective.

In the past, a CCTV surveillance system would have been considered excessive for most homes. The cameras were bulky, expensive, and required a great deal of work to install. Without security staff to monitor the cameras at all times, a CCTV surveillance system was practically useless. Modern electronics has reduced the size and cost of the various components, and wireless technology has eliminated the need for wiring back to the monitor. Digital recording allows hours of recorded video to be searched relatively quickly, and there is no longer any need to change VHS tapes every day. The video can even be sent from a remote site to a computer or a mobile phone.

The first thing to consider when looking for a CCTV surveillance system is what types of camera are required. Stylish indoor cameras can be placed in the corner of a room without creating an eyesore. Rugged outdoor cameras can withstand the elements better than indoor cameras. Pinhole cameras are mostly used for covert surveillance and are not typically used in the home. Many of these cameras also have infra-red lights mounted around the lens that allows them to see in the dark. Infra-red vision is poorer than normal light vision but it is still good enough to identify people and objects. Most cameras also have an adjustable bracket that allow them to be easily repositioned.

Home wiring is often a dirty and time-consuming job that requires crawling through roof and floor spaces. Many home owners who buy a regular CCTV surveillance system underestimate the amount of work required to install the wiring for the cameras, or they do not take into account the high cost of having it done by a professional. Another problem with using wired cameras is that some of the wiring has to be redone if a camera is moved later on. Wireless cameras are a partial solution to the problems of fixed wiring, but most still need to be wired to a power source, such as a power adapter or solar panel. Some wireless cameras are powered by batteries, but these can be a nuisance if the batteries need to be changed frequently.

At the other end of a CCTV surveillance system is the monitor, which is used solely for viewing the video footage from the cameras. Many systems also have a recorder to store the video for later use. In the past, a small television would have been used as the monitor, but modern systems typically use a LCD lat panel. Older systems used VHS tape recorders but these have been replaced with personal video recorders (PVR). A PVR stores the video as digital data on a hard drive, just like a computer does with a document or photo. Some of these systems can even send the video through a computer network and be operated from a computer anywhere in the world.

A home owner who wants to install a CCTV surveillance system should first consider buying one of the many home kits available. The kits contain everything required to setup a basic system in a home or small business. There is no need to spend a lot of time looking for the right components, and the kits generally cost less than it does to buy everything separately. A wireless kit can be installed in less than one hour but a wired kit may take considerably longer. Most importantly, the kits do not require any technical skill or special tools, although a drill and screwdriver will almost certainly be needed to attach the camera brackets.
