- 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:
Make sure that for each camera different stream IDs are selected as High quality and Low quality streams.
- 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:
- Aspect ratio should be the same for Low and High quality streams*.
- 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:
Recommended type*: VBR.
Set maximum bitrate / bandwidth limitation.
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.
