The camera tampering detection analyzes the video image to determine the nature of its change.
Name of tampering detection | Analysis result |
| Compression artifacts detection | The detection triggers when compression artifacts appear on the image |
Quality degradation | 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 |
| Blurred image detection | The detection triggers when the blurred contours appear on the image. For example, the detection tool may trigger when the image is blurry due to a dirty lens. |
Attention!
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with DetectorPack 3.7.0, the camera tampering detection has been added, which has taken over all the functions of outdated detection tools.
