Functions of the Video clarity detector

Attention!

Starting with Detector Pack 3.14, the Tampering detector has been renamed to the Video clarity detector.

Description

The Video clarity detector analyzes video image to determine the nature of its change

Type of analysis	Description
Blurred image analysis	The detector generates an event when image borders aren't clear. For example, the detector can generate an event when the image is blurred because of a dirty lens
Compression artifacts analysis	The detector generates an event when compression artifacts appear in the image
Image noise analysis	The detector generates an event when noise appears in the image. For example, the detector can generate an event when the bitrate is low or the image is rippled (snow)
Quality degradation analysis	The detector generates an event when there is a degradation in the quality of the image received from the camera. For example, the detector can generate an event when there is lens flare, severe defocusing, when camera lens closes, or when there is an abrupt decrease in image lighting
Scene change analysis	The detector generates an event when the background of the image changes, indicating a change in the position of the camera in space
