Tips to Enhance Live View Performance
Live view for multiple channels requires sufficient computing power to run the performance.
In certain extreme cases, like when viewing several megapixel H.264 video streams at the
same time, client computer will be overloaded and hence affect browse r’s performance. This
is a common limitation imposed upon all Windows based video management programs and
web browser.
To enhance live view performance, below are several tips you may try:
1. Use another browser client to share these high-resolution channels. Given that there are
32 megapixel channels to be monitored, you may have Layout 1 to display channel
1~16, set Layout 2 to display channel 17~32, then open one browser client to show
Layout 1 and the second browser on an extended monitor to show Layout 2.
2. Have CMS automatically lower the frame rate of live streams when system loading is
high. Go to Setup page  System tab Settings  Display Performance Setting
and enable this function. Basically, this setting will lower frame rate when the CPU usage
is above certain percentage. You may also enable “Lower the frame rate when current
layout is above _”, in this way, when the layout is displaying over certain number of
channels, the frame rate of all live streams will be declined. By default, this setting will be
applied to the live display of all connected web clients and Workstation clients.
A Workstation client computer can have its own specific display configuration without
being affected by CMS universal setting. Log in as CMS2 Workstation client, go to Setup
page  System tab Workstation and configure the Display Performance Setting.
