6. On the Auto tracking pane, you can create a region of interest and congure the triggering

conditions for Auto tracking.

• By default, the region of interest is the full view. Any objects entering the sheye's

eld of view will trigger the tracking.

• To congure a region of interest of your choice, click Remove and then click Add to

create a new one.

• You can then click on the screen, each click produces a red square (as a corner mark)

to mark the area. Up to 20 red squares can be applied to mark an area of a complicated

shape. Double-click on the screen to end the conguration process. Click and drag to

change the corner marks' positions.

• The green square in the middle of the screen indicates the minimum object size. Auto

tracking will be activated only if the objects entering the region are larger than the

minimum size. The smallest object size is 1.56% x1.56% of the sheye's eld of view.

You can click and drag to resize, or drag the mini. size square to a place on the screen to

compare and estimate the size of objects that might enter a region of interest.

• You can also manually enter numbers in the percentage boxes to change the size of the

minimum object size.

7. Click Save to preserve your conguration. Note that you can only congure one region of

interest, and the speed dome can track one moving object at a time.

Since only one region of interest is allowed, as long as there is an existing region, the Add

button will be unavailable.

• You can change the Sensitivity value using a pull-down menu. If you select a customized

value, a slide bar will appear allowing you to change to a value between 0 and 100. The

default is 30.
