A CCTV security camera is device that is used in capturing video or images in monitoring or surveillance systems. The camera works hand-in-hand with other components in the system, namely, video monitors and recorders to provide security for homes and businesses.

The Main Components of CCTV Security Camera Systems


1.    Surveillance Cameras

CCTV cameras are the devices that are used for capturing video and images. Security cameras come in different types, designs, styles, and configuration, depending on the following factors:

2.    Wiring/Cabling

The wiring in a CCTV security camera system is the infrastructure that is usedWhat is a CCTV Security Camera for transmission of either, analog or digital signals, from the surveillance cameras to the video recording and viewing devices.
  • In analog CCTV Systems, the surveillance cameras capture raw video footage and transmit the video in the traditional baseband format - video conversion is not necessary. Analog video can be transmitted over either, coax or the more popular Siamese wiring, which combines the video and power wiring.
  • IP CCTV Systems on the other hand, use UTP cables for transmission. The IP Cameras have powerful video encoding software, which converts the captured analog video into digital video formats. The video is then transmitted as a digital stream via the UTP5 or UTP6 cabling.
3.    Video Monitoring/Recording System

The surveillance footage from CCTV cameras is handled in two ways:
  • In analog CCTV Systems, the raw video is sent to either, a special CCTV video monitor for live viewing, or a DVR, where it is converted into digital format and stored on a hard drive.
  • IP CCTV Systems are more advanced - each of the IP Cameras is an independent device on the network. It is possible to access each IP CCTV security camera using any computer on the network or remotely via the internet, in order to view video in real time. In addition, a network video recorder enables the system to store the surveillance video on hard drives.
