:Scene Change

Description

Video scene change function is used to detect if the camera is covered or moved and other abnormalities of monitoring scene change, such as a camera being blocked, moved, intense light change, etc.

The intelligence base will compare the images before and after being covered or turned to judge if there is any similarity; if not it will generate an alarm.

Prerequisites

• Dahua product with Scene Change IVS feature

Installation Suggestions

• Avoid using a scene with a big image brightness difference after the light is turned on and off

• The camera needs some reference area with a fixed texture that is not being blocked by moving objects in the scene

• False alarms can be generated if a moving object covers most of the image, such as the crowd in the image in the lower left picture. There is no fixed area for reference which conflicts with the scene change detection. The scene in the lower right picture would be recommended, as there is a ceiling and wall used as a reference areas besides the moving crowd, which is suitable for analysis.
