All basic detection tools have a number of common settings.

If a camera supports multistreaming, select the stream for which detection is needed (1). Selecting a low-quality video stream allows reducing the load on the Server.

In the Period field (4) enter the time in milliseconds. This the time before  the next video frame is processed. This value should be in the range [0, 65535]. If the value is 0, each frame is processed.

The default setting for all detection tools (except Motion Detection) is Decode key frames (2). In this case, the frames are processed every 500 milliseconds or less often. To disable Decode key frames, select No in the appropriate field.


This setting applies to all codecs. If a codec has keyframes and p-frames, the keyframe is decoded no more often than every 500 miliseconds. For the MJPEG codec, each frame is considered to be I frame.

This feature reduces the Server load but, as can be expected, negatively impacts the quality of detection.

This setting should be activated on "blind" Servers (Servers that do not display video) on which it is necessary to perform detection.

 To configure detection of noise, blurred image and compression artifacts, do as follows:

  1. Max Processing Time is the maximum time for detection (3). If the bad image is not detected within the specified time, change the sensitivity settings.
  2. Sensitivity in standard units from 0 to 100 (5).

To save settings, click the Apply button.
