Choosing a
Camera
The camera is the ‘eye’ of a CCTV
system and at its core lies CCD
(charge coupled device) technology.
The CCD is comprised of about 500,000 light sensitive cells called picture elements
(pixels) which convert the light falling onto its surface into an electrical signal. The
performance of the camera, and ultimately the surveillance system, is more
dependent upon the quality of the CCD than any of the other camera components.
Currently, the popular formats are:
Half-inch High performance for high sensitivity and low noise
Third-inch Most popular and ideal for a wide range of applications
Quarter-inch A more recent development
Benefits of CCD Technology
Long Life Produced with a design life of up to 10 years
Shock Resistant Much more rugged than older tube technology
Size and Weight Have enabled the miniaturisation of cameras
Spectral Response Responsive in the near infra red area
