Yes,
It is possible to take pan tilt zoom controls of your PTZOptics camera from the far end with Zoom Video Conferencing. You must be the host of the video conference to take camera control and the far end must approve far end camera control. You also must have far end camera control enabled on your account which can only be done by the owner or adminstrator of your account. Once you are in the video call and you are the host you can right click the video you want to take control of. If the camera is a PTZOptics camera (or a UVC controllable camera) you can request far end camera control. Once you have requested control the far end will be prompted to accept or deny that control. Once accepted pan tilt and zoom controls will show up in the right hand corner of the Zoom video panel.
