To ensure optimal performance, do not exceed the maximum number of camera streams supported by a Media Gateway in Security Center 5.11.
Media Gateway agents provide video streams to the Security Center Web Client, Genetecâ„¢ 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:
|
Genetecâ„¢ Web App | Only in the following situations:
|
Web Client | Only in the following situations:
|
The maximum number of camera streams supported by a dedicated Media Gateway server in Security Center 5.11 is as follows:

Considerations
There is a hard limit around 500 connections, the values in the table are obtained with 30 fps, if the framerate 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 640x480 (VGA) or less, maintaining the aspect ratio.
