The core component behind all CCTV surveillance cameras is a CCD, or charge coupled device, sensor. This sensor converts the light that comes through the cameras lens into an electrical signal.

How the video signal is created and transmitted varies depending on whether the video camera is analog or digital. We will explore the difference between the two in further detail below.
