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

Name of a Detection Tool object | Detection description | ||||
Quality degradation | A detection tool which is triggered 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 analysis | The detection triggers when video noise appears on the image For example, the detection tool may trigger upon low bit rate or ripples in the image (snow) | ||||
Scene change analysis | A detection tool triggered by a change in The detection triggers when the background of the video image | background changes, indicating a change in the position of the video camera | 's position 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 analysis | 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 | Detects compression artifacts

Starting with DetectorPack 3.7.0, the compression artifacts detection, quality degradation, image noise detection, scene change, and blurred image detection are marked as obsolete. If they were in the configuration, then after you update to DetectorPack 3.7.0 and later, they will remain in the configuration, but once you delete them it will not be possible to re-create them. Starting with DetectorPack 3.7.0, a camera tampering detection is added, which now performs all the functions of legacy detection tools. |
