PTZ Camera

PTZ Camera

PTZ camera (Pan Tilt Zoom) is a camera that automatically turns towards the speaker, following preset positions with the help of a rotary device. PTZ cameras can rotate, tilt, and zoom picture thanks to the special mechanical/electronic drives. PTZ cameras are equipped with a variable focal length lens. PTZ cameras have a wide range of view provided by a built-in rotation mechanism.

Controlled PTZ camera is an integral part of the surveillance system. It is used both for outdoor and indoor surveillance. During a video conference, PTZ camera plays the most important role as an inevitable attribute of the conference room or meeting room.

The key features of a PTZ-camera:

  1. The image quality is provided by CCD sensor. Color reproduction depends on the size and the quality of that sensor. Some PTZ-cameras provide high-quality recording even in low-light conditions. This property is particularly important for video conferencing as most conference rooms are under-equipped in terms of illumination.
  2. Preset positions. PTZ cameras have a different number of presets - from five to a hundred. The more preset positions a PTZ-camera includes, the better.
  3. Range of rotation and tilt. PTZ camera should have a wide range of tilt/rotation angles at a maximum speed.
  4. CleverMic PTZ CameraCeiling/desktop/wall installation. PTZ-cameras can be mounted anywhere in the room with special brackets.
  5. PTZ mechanism. It determines the range of pan, tilt and zoom.
  6. Control. You can control PTZ the tilting, zooming and panning features of the camera using various interfaces (like IR remotes and controllers).
  7. Alarming function. This feature is supported by most PTZ cameras. "The alarm" is activated when the illumination changes in a particular area.

PTZ camera can be aimed at a particular speaker during a video conference or at the entire conference room with an optical zoom and servo unit. TrueConf Terminal hardware video conferencing system supports PTZ camera control from a touch-panel since version 1.3.0.
