The number of video streams and amount of traffic that Security Center 5.9 can deliver vary depending on the camera stream settings, the Media Gateway role settings, the dimensions of the requested video, and the performance of the server that hosts the Media Gateway and Web Server roles.

The Media Gateway role is used by Genetec™ Mobile and Web Client to get transcoded video from Security Center. The Media Gateway role supports the Real Time Streaming Protocol (RTSP), which external applications can use to request raw video streams from Security Center.
The stream settings are configured in Config Tool. For more information, see the followings topics:

The following tests were conducted on a server with an Intel Xeon E5-2620 v4 Quad-Core Processor at 2.10 GHz with 16 GB RAM, running Windows 10 64 bit, the Web Server role, and the Media Gateway role.

NOTE:
  • In our tests, the Web Client streams MJPEG at 8 fps.
  • The calculation for the transcoded outbound network traffic bit rate includes an additional 15% overhead, but also depends greatly on the content of the video (the encoder targets 80% quality factor). For example, if the table indicates a transcoded outbound network traffic bit rate of 65 Mbps, the calculation is as follows:

    New bit rate (325 Kbps) x 180 streams = 58500 Kbps or 57 Mbps + 15% overhead = approximately 65 Mbps

  • To save system resources, you can cap the transcoded resolution by limiting Media Gateway connections.

1 The Web Server automatically transcodes the video stream when required, which can result in a different bit rate than the original stream.
