All basic detection tools have a number of common settings.

  1. 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.

  2. The default setting for all detection tools is Decode only 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.

    Important

    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.

  3. Select a processing resource for decoding video streams (3). When you select a GPU, a stand-alone graphics card takes priority (when decoding with NVidia NVDEC chips). If there's no appropriate GPU, the decoding will use the Intel Quick Sync Video technology. Otherwise, CPU resources will be used for decoding.

  4. Event duration to trigger detection (sec.) is the maximum time for detection (4). If the bad image is not detected within the specified time, change the sensitivity settings (6).
  5. Set the frame rate value for each detection tool to process (5). This value should be in the range [0.016, 100]. 
  6. Sensitivity in standard units from 0 to 100 (6).
