Enable PTZ on a video encoder

To enable the use of PTZ cameras on a video encoder, do the following on the PTZ tab:

1. In the list of devices connected to the video encoder, select the Enable PTZ box for the relevant cameras:

   

2. In the PTZ Device ID column, verify the ID of each camera.
3. In the COM Port column, select which video encoder's COM (serial communications) ports to use for control of the PTZ functionality:

   

4. In the PTZ Protocol column, select which positioning scheme you want to use:

   

   • Absolute: When operators use PTZ controls for the camera, the camera is adjusted relative to a fixed position, often referred to as the camera's home position
   • Relative: When operators use PTZ controls for the camera, the camera is adjusted relative to its current position

   The content of the PTZ protocol column varies a lot depending on the hardware. Some have 5 to 8 different protocols. See also the camera documentation.

5. In the toolbar, click Save.

   You are ready to configure preset positions and patrolling for each PTZ camera:

   • Add a preset position (type 1)
   • Add a patrolling profile
