The PTZ-camera or Speed Dome Camera (SHORT PAN-TILT-ZOOM, pens Speed Dome Camera.) - A robotic-controlled video camera with built-in electronic-mechanical drive.
Built-in optical power zoom with variable focal length allows you to remotely change the angle of vision of the camera (optical magnification or reduction of the observed object), and an electro-mechanical actuator enables to control the rotation or tilt of a PTZ camera. Control the camera remotely using a special remote control, or specialized software (CMS, Web-server) if the connection to the camera occurs on the network protocol.
In our time of PTZ camera is widespread in security systems and occupy a special place among the cameras. The use of cameras of this type, allows to solve the problem of video monitoring forlarge open space by the Office of regulation review zone. PTZ cameras can be used both indoors and outdoors. Built-in heating components and sealed enclosure (The housing), allows to operate PTZ-camera in the northern areas and the southern to the very hot climate. Some versions of the cameras can be used in extreme conditions, where it is impossible to find a person (nuclear and chemical industry).
