The CCTV Guide
What is CCTV? How does it work? Where can I buy Security Equipment from? Well before we answer that for you, lets have a look at a few things here.
1) CCTV stands for Closed Circuit Television. A CCTV system would primarily consist of CCTV cameras and in most cases connected to a recording device. CCTV security systems are used to monitor events or areas where there is a concern for security and safety and records images of those scenes. Of course CCTV has come a long way now and a range of additional features are used in conjunction with the systems which we will explore in a future blog.
2) So how does it work? The cctv cameras collects images and sends the signal to a recorder. The recorder, or now commonly known as a DVR [ Digital Video Recorder ] would digitally store the images. The images are viewed on a TV Monitor. The quality of the camera, usually measured in TVL [ Television Lines ] and the focal length of the lens on the camera would determine what the user sees on the monitor.
3) Where can I buy CCTV Equipment From? There are many vendors of CCTV equipment, and with ever growing interest in Surveillance, many manufacturers, distributors and installers are popping up. Our best advice is to do your homework. Exploring the Internet isa good start, look for sellers who can offer a range of equipment right up to brand names as they can offer you the best choice of equipment. In addition they would have more experience with different equipment and can best advise you for your needs.
