A CCTV system (closed circuit television) is a group of video cameras that are placed around a certain object for security purposes. This is usually expensive to operate and the start-up costs are often costly. This method of security is highly regarded and can be very effective if used properly. CCTV security systems can also be wired to a motion sensor device and also an alarm system.
A CCTV camera system is often placed around a house or building and even in some cases around a very important object. This is a form of surveillance. This Is because of the fact that these CCTV cameras are being watched. They are all connecting back to main area. This unusually involves a security guard watching all the cameras and he/she can then alert people to a problem. In some cases and in particular in the case of a home, they can connected back to a computer that will record everything and only if an incidence has occurred can the video be retrieved. This is cheaper than hiring a guard. In some cases these are wireless cameras.
There is often a wide range in CCTV camera prices. This is because there are several different companies making these cameras. There are also several different functions that come with these cameras, in so some of the very basic modules they only come with being able to record in the day. In some of the very advanced modules they come with being able to record in the night, come with motion sensor and in some cases even come with infra-red technology.
DIY CCTV systems are marketed towards the middle class home owner. They are often very easy to install and can be relatively cheap considering the advanced technology. These systems can be found at some electronic stores but mostly at a specialised security store. In some instances if the person struggling on their own they can call out a person to help with the installation. These DIY kits are very comprehensive and often come with everything that a person might need for the installation. It also comes with a detailed instruction manual.
