It differs from broadcast TV in that its elements are directly linked (i.e. closed circuit) by cables or different wireless technologies. CCTV systems are used mainly in large public areas like: banks, malls, train stations, sport stadiums and in almost every large store. This type of surveillance system is extremely efficient in monitoring large crowds in real-time.Basic Components of CCTV SystemsThe basic CCTV system can be divided into three components: A camera, a monitor and a time lapse recording mechanism (usually made in VCR or DVR formats). These are only the fundamental components. For larger areas or for real-time monitoring you will probably need to add cameras, monitors and other special devices. For a common size household, the most suitable system is a quad cam. This basic kit consists of four wireless surveillance cameras, a small monitor and a recording device. The camera kits vary depending on their use. Some camera kits can be used on a computer, taking advantage of its monitor and memory. Others have a monitor and a time lapse VCR in the same console.Home security cameras offer reassurance in the protection of your property and family.
