If the video you’re monitoring is jittery or is dropping frames, use the rendering rate video statistic to determine whether the workstation is the cause.

What you should know

Rendering rate is the comparison of how fast the workstation renders a video with the speed the workstation receives that video from the network. The rendering rate video statistic is made up of:
  • The speed at which the workstation processes video. This indicates how much load is on the workstation's CPU and memory.
  • The speed at which the network is sending video to the workstation.

Procedure

  1. Select the tile that’s playing video.
  2. Press Ctrl+Shift+A.
    Video stream statistics are displayed in the tile.
    Video stream statistics are displayed in a Security Desk tile

Example

If your rendering rate is "12 rendered fps on 19 fps", your workstation is processing 12 fps. However, it’s receiving video at 19 fps. The workstation can’t process all the frames it’s receiving. Your workstation is the cause of the degraded quality of the video that you’re monitoring. In this case, lighten the load and check the hardware and its drivers.
  • Reduce the number of cameras that you’re monitoring to reduce the load on the workstation.
  • Check the hardware requirements to make sure that the workstation can handle the load.
  • Check that the graphics card and video card drivers are up to date.
  • Check that the network card is up to date.
  • Ensure that all drivers are up to date.
If your rendering rate is "12 rendered fps on 12 fps", your workstation is processing every frame that it’s receiving from the network. In this case, compare the second value to the camera's configured fps rate. This determines if the network is sending all the frames it’s receiving from the camera. If there’s a difference in these two rates, either the camera or the network is the cause of the video degradation.
  • Check the camera's firmware.
  • Check the health of the network.
