For the best possible experience in Security Center Web Client 5.11, plan for the maximum number of simultaneous user connections and approximate amount of traffic.
How many users can a Web Server serve?
As more streams are requested simultaneously, more load is placed on the server. If the server becomes overloaded, users can experience slow Web Client pages.
To plan how many Web Servers you need, determine the maximum expected amount of traffic during peak hours. The amount of traffic depends on the number of users that log on at the same time and the camera quality settings. Then choose the server hardware that best manages that load.
The following table shows examples of how many users can view a single video stream in Web Client at the same time. The results are based on tests performed in our lab on a server that meets the recommended hardware configuration.
| User activity | Number of concurrent user connections | Camera video quality setting |
|---|---|---|
| Monitoring one live MJPEG (640 x 480) video | 60 | H.264 (640 x 480), 15 fps @ 500 Kbps |
| Monitoring one live H.264 (640 x 480) video | 100 | |
| Generating reports and managing cardholders only. | 100 | No cameras in system. Access control only. |
What is a user connection?
A user connection is any user account that logs on to Web Client. Even if 50 users log on using the same user account, there are 50 user connections.
How can I increase the number of concurrent user connections?
- Deploy high-performance server hardware.
- Reduce the video quality of cameras.
- Add more Web Servers.
