The camera tampering detection analyzes the video image to determine the nature of its change.

Detection descriptionA detection tool triggered by a change in background 's position Detects compression artifacts 

Name of tampering detection

Analysis result

Compression artifacts detection

The detection triggers when compression artifacts appear on the image

Name of a Detection Tool object

Quality degradation

A detection tool which is triggered The detection triggers when the video image received from a video camera loses quality.

For example, the detection tool may trigger upon excessive light, loss of focus, lens blocking, or sudden drop in scene illumination.

Image noise detection

The detection triggers when video noise appears on the image

For example, the detection tool may trigger upon low bitrate or ripples in the image (snow)

Scene change

The detection triggers when the background of the video image

changes, indicating a change in the position of the video camera

in space

Image Noise Detection

A tool that triggers in the presence of video noise.

For instance, triggering may occur upon low bit rate, or ripples on video.

Blurred image detection

The detection triggers when the blurred contours appear on the image.

Blurred Image Detection

A tool that detects blurred contours. 

For example, the detection tool may trigger when the image becomes blurry because of is blurry due to a dirty lens.

Compression Artifacts Detection


Note
titleAttention!

Starting with DetectorPack 3.7.0 and later versions, the compression artifacts, quality degradation, image noise, scene change, and blurred image detection tools are marked as obsolete. If they were present in the system configuration, then after updating to DetectorPack 3.7.0 and later versions they will be saved in the configuration, but it will not be possible to create them after deletion.

Starting with DetectorPack 3.7.0, the camera tampering detection has been added, which has taken over all the functions of outdated detection tools.
