A: The camera connected to the channel being viewed may not actually be a PTZ camera
(not all surveillance cameras are PTZ cameras), in which case, the PTZ controls will not be
effective. Or the camera itself may have hardware problems (i.e. it may not be able to pan, tilt,
or zoom properly, even when operated locally). To solve this problem, first check that the
camera recording the video that is currently being viewed is actually a PTZ camera; next, check
to make sure that it is properly set up and does not have any damaged or dysfunctional parts.
B: The remote PTZ control function might take more time to load than expected depending
on the Internet connection; be patient – wait and then try using the controls again.
