Note: Please note that if enabling the Pan/Tilt Limits function, the position of the Start Point
should be within the range of the Pan/Tilt Limits, or there will be a pop-up message showing
"Setting error: Start Point is not inside Pan/Tilt Limits".
Zoom control on tracking:

Keep current zoom ratio: the current zoom ratio will stay fixed during the tracking process.
Multi-step zoom function: the zoom ratio will change according to the distance of the
object against the camera. When the object is moving further away, the camera will keep
zooming in to track; on the other hand, when moving closer, the camera will zoom out to
check whether it should track the object or not.
Tracking Duration: User can set the tracking time duration of the camera (0~600 seconds).

When the Tracking Duration is up, the camera will return to the Start Point. The function is
used to prevent the camera from tracking an object which is intentionally set to lure the
camera away.
When the object is lost on the screen: User can select a tracking mode when the object is

lost on the screen. The options are:
Keep tracking: The camera will stop at the current position and wait for another moving
object in the camera's field of view. Then, the camera will track the new object without
changing zoom ratio.
Zoom out and look for a new object: The camera will zoom out at the current position
immediately for expanded the field of view and restart tracking a new moving object
appearing in the camera's field of view.
Stop tracking and zoom out: The camera will stop auto tracking and stay at the current
position. Then, the camera will zoom out for expanded the field of view.
In sec and Back to Start Point: Set up a period of time for the camera to stay at the current

position before returning to the Start Point (0 is returning to Start Point without any
waiting).
Resume from manual stop: The function is used to set up the Auto Tracking restart time

(0~600 seconds). If user manually operates the PTZ function during auto tracking process,
the auto tracking function will stop. When the manual operation ceases, the camera will
resume to "Auto Tracking Start Point" after a given period of time. Setting of value 0
indicates do not restart.
Note: In the on-going auto tracking process after object is identified, the PTZ function keeps
the moving object in the center of the screen. But the PTZ function may stop if the object
moves too slow and stays in center of the screen too long. In case like this the auto tracking
may incorrectly assume the object is lost and ends the tracking process.
