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)
