Video units offline in Security Center - Security Center 5.7 - 5.11

When a camera is red in the area view, it means that the video unit is offline or has lost communication with the Archiver. To troubleshoot the issue, learn about the possible causes and their respective solutions.

1. Verify that you can ping the unit:
   1. In the Config Tool Video task, select the red video unit.
   2. At the bottom of the Video task, click Unit > Ping ().
