subject: Cctv Installation: Different Types Of Cctv Cameras [print this page] Different Types of CCTV Cameras: Different Types of CCTV Cameras:
There are various different types of cameras on the market, from your infra-red cameras to PTZ cameras (which are pan, tilt and zoom cameras).
Your infra-red cameras are cameras that do not need any external lighting. The cameras are able to operate in complete darkness and the infra red is de-activated when there is enough light in the environment.
Your PTZ cameras (which are the pan, tilt and zoom) are remotely operated.
Then you have your CS mount cameras. These are cameras which are installed inside a house.
They are normally indoor cameras and they are not waterproof because their purpose is not to be used out of doors unless they are in a completely waterproof housing.
What sort of technology is used in CCTV systems?
Modern CCTV systems involve a linked system of cameras with full PTZ (or pan, tilt, and zoom) features able to be remotely operated from a control room.
These systems may involve sophisticated technology. Features may include night vision (or infra-red), computer assisted operation and motion detection facilities, which allows the operator to instruct the system to go on red alert when anything moves in view of the cameras.
Camera systems increasingly employ bullet-proof casings, and automated self defense mechanisms which - as with the Liverpool system - ensure that cameras under attack are covered by neighboring cameras. These can be legitimately described as military style systems.
The clarity of CCTV footage is often excellent, and has grown past the point of being able to recognize a packet of cigarettes from a hundred metres to a kilometre. The systems often work in pitch blackness, bringing images up to daylight level.
