To ensure optimal performance, do not exceed the maximum number of camera streams supported by a Media Gateway in Security Center 5.12.

Media Gateway agents provide video streams to the Genetec™ Web App, Genetec™ Mobile app, and external RTSP connections. In some cases, video transcoding might be required. Video stream transcoding is determined by the requesting application as follows:

Requesting application Transcoded?
External RTSP connections Never
Genetec Mobile Only when all the following conditions are met:
  • Media Gateway Allow transcoding setting is enabled for the Mobile Server role
  • Mobile role allows the use of MJPEG streams
  • Original stream is not H.264
Genetec™ Web App Only in the following situations:
  • Requesting user has video watermarking enabled
  • Requesting user is streaming a PTZ camera and moving it (PTZ widget)
  • Browser does not support H.264 decoding through Media Source Extensions
  • Original stream is not H.264
Security Center Web Client Only in the following situations:
  • Requesting user has video watermarking enabled
  • Requesting user is streaming a PTZ camera and moving it (PTZ widget)
  • Browser does not support H.264 decoding through Media Source Extensions
  • Original stream is not H.264

The maximum number of camera streams supported by a dedicated Media Gateway server in Security Center 5.12 is as follows:

NOTE: Bitrate is for input streams only. Output resolution is VGA.

Considerations

  • Video watermarking requires extra processing of transcoded video frames. If watermarking is applied to all streams, the maximum number of Media Gateway camera streams is reduced by 30%.
  • There is a hard limit of around 500 connections.
  • The values in the table are obtained with 30 fps.
  • If the frame rate is reduced and the throughput remains under the maximum values in the table, then the number of connections can be increased linearly.
  • When transcoding, output is resized to resolutions of 640 x 480 (VGA) or less, maintaining the aspect ratio.
CAUTION:
Do not host Media Gateway on the same server as an Archiver. The Media Gateway role can use significant processing power. High CPU usage on the Archiver server can result in Archiving queue full situations that might lead to data loss.
