Surveillance cameras with PTZ capability will often also support user defined preset positions which will allow the user to specify a number of positions that they can easily monitor. Preset positions can also be used with alarm triggers, so for example when a camera detects motion it can be directed to move to a specified preset covering an entry/exit point or a valuable object in the room. Some cameras also support guard patrolling and auto panning features which will allow the camera to move automatically between user-defined preset positions providing remote surveillance of a wide area with no user input. In conjunction with motion detection some cameras can even use their pan-tilt functions to follow moving targets.
