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.Other more for your reference:
