Page History
The camera tampering detection analyzes the video image to determine the nature of its change.
Name of tampering detection tool analysis | Analysis result |
| Compression artifacts detectionanalysis | The detection triggers when compression artifacts appear on the image |
Quality degradation analysis | 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 detectionanalysis | The detection triggers when video noise appears on the image For example, the detection tool may trigger upon low bitrate bit rate or ripples in the image (snow) |
Scene change analysis | 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 detectionanalysis | 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. |
