Description
When motion detection is enabled, the PTZ IP camera monitors activity in regions
of the video that you specify. If activity at a defined level occurs in any of these
areas, the PTZ IP camera generates an alert and takes the actions that are configured
as described in the
"Event Notification Window" section on page
After motion detection has been enabled, you create specific regions that the PTZ IP
camera monitors for activity. To create a motion detection region, right-click on the
video image, choose Draw Region, and then click and drag across the motion
detection grid to draw a green square or rectangle comprised of one or more grid
squares. Up to eight of the following regions can be drawn:
Motion inclusion regions—Designate areas to examine for motion. You can
•
draw up to four motion inclusion regions.
Motion Exclusion Regions—Designate areas to ignore for motion. You can
•
draw up to four motion exclusion regions.
For each region listed under the Region Properties area, you can configure the
following properties:
IsActive—Specifies whether the region is active (enabled) or not active
•
(disabled). Chose true to enable a region; choose False to disable a region.
Location—Specifies the grid coordinate (X, Y) for the upper left corner of the
•
region.
Name—You can enter a name of up to 12 characters for a region.
•
Region Type—Specifies whether the region is an inclusion or an exclusion
•
region. Choose Inclusion to have the region examine for motion; choose
Exclusion to have the region ignore motion.
•
Sensitivity—Designates the relative amount of activity that the PTZ IP camera
must detect in the area before it generates an alert. A lower value means that
more, or faster, activity is required to trigger an alert. A higher value means that
less, or slower, activity is required. The default value is 80.
Threshold—Designates the percentage of pixels that the PTZ IP camera must
•
identify as changed in the area before it generates an alert. The camera detects
pixel changes at the defined sensitivity level. The default threshold value is 10.
To reset the sensitivity and threshold to their default values of 80 and 10
respectively, right-click on the region, and choose Restore Values.
To remove a region, right-click it, and choose Delete Region.
