Hi, 
The camera's privacy zone is fixed relative to the camera lens, not to a specific physical location in space. 
If your TC70's motion tracking feature is disabled, you can manually pan & tilt the camera to the position you want. If the motion tracking feature is enabled, a set privacy zone may not be helpful in your situation, as it will move with the lens. 
You can try placing the camera in a different location that won't face the TV.
Best Regards
