of camera are designed for difference applications, e.g. indoor, outdoor,environmental
and lighting. Dome type is the most common and it is mostly used indoor. For outdoor
type, auto-iris and variable focal length lens should be used.. For dark place, camera
with Infrared Red light is required. However, manufacturers are now incorporating
IR features in all their camera. Powerful Speed Dome camera with pan, tilt and zoom

power/utilities and military installations.
Digital Video Recorder (DVR) provides live viewing, multiplexing - the displaying
of multi cameras into single monitor, recording, playback and network/Internet functions.

CCTV an abbreviation for Closed Circuit TeleVision. However due to it is no longer
‘closed circuit’ as opposed to ‘Television’ which is broadcast -open, during earlier
day, it is not an appropriate term anymore. But it is still commonly used for convenience.
Video Surveillance Systems are very affordable now due to it very low price caused
by stiff competitions among manufacturers, suppliers/importers and installer/security
integrator. So it is helping many homes, businesses and organizations in maintaining
security in their premises.
Another type of system which use IP or Network Cameras and Network Video Recorder
is gaining popularity. IP cameras is increasingly using Megapixel technology to provide
