Enable PTZ on a video encoder
To enable the use of PTZ cameras on a video encoder, do the following on the PTZ tab:
- In the list of devices connected to the video encoder, select the Enable PTZ box for the relevant cameras:

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

 - 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.
 - In the toolbar, click Save.

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