Advanced Scene Change Detection
Compared to Scene Change Detection that can only be applied in the indoor, the advanced version of
Scene Change Detection can be applied in the outdoor scenes with sudden light changes, thus
avoiding false alarms. The Advanced Scene Change Detection detects and prevents any changes of
scene, viewing angle or focus clearness made by malice.
Note:
1. This function is only available when an AVP dongle is used. Up to 16 cameras can be configured
for this application.
2. It is highly recommended not to use Advanced Scene Change Detection and Scene Change
Detection together.
1. On the main screen, click the Configure button, click Advanced Video Analysis, and select
Advanced Scene Change Detection Setting.
2. Select the desired camera(s) to be configured, and click Configure. This dialog box appears.
