100 - User's Manual

NOTE:

The conditions for using this function are listed below:

1. The speed dome can track one object at a time.

2. If multiple objects are present in the FOV, the camera tracks the object that is farthest from the

camera.

3. If a tracked object stays motionless for 10 seconds, camera will abandon it and start tracking another

object that is farthest away from the center.

4. The zoom-in ratio while tracking is determined by the zoom ratio of the camera lens when the tracking

is triggered.

5. Manual control always has a higher priority than Auto tracking, such as using a joystick to pan or tilt or

using a click on VAST view cell.

6. Objects can easily move away from an FOV when the zoom-in ratio is high. Therefore, it is

recommended not to zoom in too much on where the Auto tracking is expected to take place.

Auto tracking is congured by designating the minimum object size. Moving objects larger than the min.

size that entered the current region of view will trigger the tracking action.

Auto tracking, if applied, is designed to track an intruder in a place where human trafc is not heavy, such

as a warehouse or a load area. Heavy trafc can result in a constant shift of tracked objects, and reduce

the effectiveness of the feature.
