You can minimize the time it takes for a camera to open and display live video in the Security Desk Monitoring task by adjusting settings in Config Tool and Security Desk.

What you should know

Several factors affect the time it takes to display live video from a camera in Security Desk:
  • Video compression format: MJPEG video streams usually display quicker than H.264 video streams.
  • Image quality: a camera usually displays live video quicker with video image quality of 70% than with video image quality of 100% or below 60%.
  • Key frame interval: setting a low Key frame interval for the camera in Config Tool might produce better results.
