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 that 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.
Procedure
-
From the Config Tool homepage, open the Video task and click the
Roles and units view.
-
Select the camera to configure and click the Video tab.
-
In the Stream usage section, turn on Live
and Recording for the selected stream.
-
Configure the Network settings based on the network configuration
and setup:
- Select Multicast for the Connection type if the network
equipment is configured for multicast streams.
- Select Unicast, UDP, or RTSP stream over TCP if the network equipment is not
configured for multicast. Ensure that the connection type selected provides the
fastest connection time.

Click Apply.
In the Network settings section, select Multicast as the Connection type but only if

connection types (for example Unicast UDP or RTSP stream over TCP) until you find the
connection type that provides the fastest connection time.
