For the pan:
(Motion tracking with motion detection zone ) Ability to control how long the camera remains in its position after detecting motion before going back to home. Often it will follow the motion source, but the motion will stop for a few seconds and continue, but by then the camera has already returned home and cannot see the object anymore.
Ability to control the amount of travel that the pan uses when detecting motion- that is if it sees motion moving left on the screen it usually jumps way further left than needed and bounces back and forth. - in the same idea, the ability to control how ‘hard’ the camera tries to center the motion, often the motion will move around the viewing area but moving the camera is not necessary- but the camera tries to center the motion so much that it is constantly moving.
