same channel.

9.4 Intrusion Detection

Purpose

The intrusion detection function detects people, vehicles, or other objects that enter and

loiter in a pre-defined virtual region. Certain actions can be taken when the alarm is

triggered.

1. Go to Menu > Camera > VCA.

. Select the camera to configure the VCA.

3. Check the Save VCA Picture checkbox to save the captured VCA detection pictures.

4. Set the VCA detection type to Intrusion Detection.

5. Check the Enable checkbox to enable this function.

6. Click Set to configure the trigger channel, arming schedule, linkage action, and PTZ

linking for the intrusion detection alarm.

7. Click Rule Settings to set the intrusion detection rules. Set the following parameters.

• Threshold: Range [1s-10s], the threshold for the time the object loiters in the

region. When the duration of the object in the defined detection area is longer

than the set time, the alarm will be triggered.

• Sensitivity: R

ange [1-100]. The value of the sensitivity defines the size of the object

that will trigger the alarm. The higher the value, the more easily the detection

alarm is triggered.

• Percentage: Range [1-100]. Percentage defines the ratio of the in-region part of the

object that will trigger the alarm. For example, if the percentage is set to 50%,

when the object enters the region and occupies half of the whole region, the alarm

is triggered.
