Time Mask: Check the box to enable the following Time Mask functions.

 Zoom Control on Tracking: The camera has two zoom control modes while 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 three 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 FOV 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 FOV.

 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.

 Object Frame: You can set the frame of the object being tracked visible or invisible.

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.
