What are the different types of surveillance systems?
There are simple or elaborate surveillance systems to meet your needs. Basic camera systems include a single camera connected directly to a VCR for recording. If more than one camera is installed then a quad or multiplexer switcher, which allows you to switch between cameras, will be necessary. Only one camera can be seen at a time. A quad will display four cameras simultaneously on a monitor in a split screen view. Multiplexers will allow you to use several cameras and are available in an assortment of styles.
