Below is a brief description of some of the components that make up a CCTV System.

Cameras
 Camera - DomeEach camera unit consists of a high resolution colour or black and white (monochrome) camera fitted with a suitable auto iris lens. If the camera is to be installed externally then it would be protected within an IP65 rated weather proof heated housing.
The camera can have telemetry controls allowing the camera to be controlled e.g. pan, tilt and zoom functions by programmed pre sets or via a controller at a separate location.

Duplex Multiplexer
KeyboardThe multiplexer is responsible for the rapid transferance of each camera's image to the time lapse VCR or Digital Recorder. The images can be viewed in either single screen format or as a multi view, either live from each camera or recorded and played back from a VCR or Digital Recorder. The duplex multiplexer splits the image from each camera so an operator can view any camera in any format without affecting the recording of the overall system.

Time Lapse VCR (Gradually being phased out)
Remote ControlLocated close to the multiplexer, the standard VCR can be programmed in either 24 hour or 96 hour (to cover weekends) mode on a single 4 hour tape. VCRs are also available so as to record up to 960 hours. So the recordings can be used for Police evidence, the time and date is shown on the recording.

Digital Recorder

Digital RecorderThis is the latest way to record picture images, digitally onto a hard drive. This gives you all the controls of a VCR but with no tapes or moving parts and gives faster retrieval of data with greater clarity. It can also be viewed remotely on a password protected PC.

9 Way Digital Recorder

Monitor
These come in a variety of sizes, and are used to view colour or black and white images either live or recorded/played back via a VCR or Digital Recorder.
