Configuration Guide

9.1 Configuring the Intrusion Detection Function

The intrusion detection function checks whether an object enters a sensitive area (a key
surveillance area for which behavior analysis rules have been configured). The system
generates an alarm when an object enters a sensitive area.
Prerequisites
Predefined sensitive areas for behavior analysis can be displayed on live video images only
when Video stream type is set to Hybrid stream. To set Video stream type, choose Settings
> System Configuration > Local Parameters.

Ensure that the camera lens is not blocked by objects, for example, leaves and columns,
to effectively and continuously track the object. Do not directly place the camera lens
opposite to a light source, water surface, or reflection plane, to prevent interference or
false alarms.
Before configuring the intelligent analysis function, ensure that the camera lens is
focused accurately, video images are clear, and light conditions are proper. If the
illuminance is lower than 20 lux, or video images are not clear with much noise, set
artificial light sources for light compensation to ensure even and proper light.
During the intelligent analysis test, the angle between the horizontal view angle of the
camera (that is, the optic normal of the camera lens) and the level ground or plane of the
monitoring object (for example, wall), must be greater than 15 degrees (reference: 30
degrees to 45 degrees) to ensure that the top of the monitoring object is covered.
The camera installation height must be determined based on the site requirements
(reference: 5 m to 6 m for tilted installation and 3 m to 5 m for vertical installation). A
proper installation height can ensure that the object size displayed in video images is
greater than the minimum object size and less than the maximum object size. It is
recommended that the object size be 1/8 to 1/3 of the image size.
It is recommended that Frame rate be set to 10 or higher on Settings > Channel
Configuration > Video&Stream Parameters to prevent impact on the behavior
analysis effect, for example, the object box is lost, the object box does not match the
object size, or all object boxes are displayed with delay.
