  •  Connect the cameras to the Servers.
  •  Synchronize the time of all Servers and cameras with a single NTP server.
  •  Add the cameras to the system (see Adding and removing IP devices, Bulk creation of IP devices). Preferred protocol: ONVIF generic.
  •  

    Multistreaming:

    1. Make sure that for each camera different stream IDs are selected as High quality and Low quality streams.

    2. Low quality stream settings should be lower than the High quality stream.
  •  Codec type*: H.265 or H.264 is recommended. If you plan to use the Web Client, then H.264 is recommended since using H.265 leads to the stream recompression on the Server side.
  •  FPS: the Low quality stream frame rate should be at least 6 to ensure the correct operation of the detection tools.
  •  Resolution:
    1. Aspect ratio should be the same for Low and High quality streams*.
    2. The Low quality stream resolution should be no less than 640x360 and no more than 1280x720 to ensure the correct operation of the detection tools.
  •  Bitrate: 

    1. Recommended type*: VBR.

    2. Set maximum bitrate / bandwidth limitation.

    3. Recommended bitrate: 1 mbps per 1 MP.

  •  GOV (also known as GOP, I Frame, etc.): it is recommended to have at least one keyframe per second. 

    *May differ for different camera models.

  •  The motion detection tool should operate on a low quality stream (see Configuring VMD).
  •  Configure masking (exclude areas) of the frame areas which constantly trigger motion detection (for example, on-screen display (OSD) or TV).
  •  Create automatic rules for recording to the archive (see Automatic Rules).
  •  Use a NVIDIA GPU for the detection tools operation if there is one.
