Hi all. I inherited responsibility for maintaining old ZoneMinder servers and deploying new ZoneMinder servers.
- Our old RHEL 7 servers run ZoneMinder 1.30.4-1
- Our new RHEL 8 servers run ZoneMinder 1.34.26-1
- One of our new RHEL 8 servers was updated to ZoneMinder 1.36.5-1
Several cameras have a red circle icon and red IP address in the console view when connected to 1.36.5-1. These cameras, and cameras of the same make, model and configuration, work properly when connected to 1.30.4-1 and 1.34.26-1. I deployed a new server also running ZoneMinder 1.36.5-1, but it has the same problem with the same cameras. There are messages like this in /var/log/zoneminder/zmwatch.log:
Code: Select all
11/29/2021 03:46:48.610403 zmwatch[2221].INF [main:143] [Restarting capture daemon for BAD-CAMERA, shared data not valid]
11/29/2021 03:46:58.820930 zmwatch[2221].ERR [main:167] [Last analyse time for 4 BAD-CAMERA was zero.]
I am not very familiar with ZoneMinder or surveillance infrastructure in general, but our SME is stumped. How can I troubleshoot this to better understand the problem?
