Camera still thinks it's linked

I configured three of my cameras to modect and low res and then linked the high res version of the camera as nodect.
I have since changed the config and removed the low res version of the cameras and removed the high res camera link to them.
The log file now gives regular warning messages saying the linked cameras cannot be found so it seems something has been left behind.
Any clues anyone please?

Logon to mysql with mysql -u root -p then run the following commands:
Code: Select all
show databases;
use zm;
show tables;
select * from Monitors\G
Do any monitors have entries for the LinkedMonitors field? Have you restarted ZM?

Yes, the three cameras that used to be linked have a value in the LinkedMonitors field.
I have restarted ZM several times since I deleted the linked cameras.

Are you sure the entry from LinkedMonitors is deleted on the settings page for the cameras? Sounds like it didn't delete correctly.
Delete the entries for the linkedmonitors field. Either using phpmyadmin, or a mysql query from the DB and you should stop receiving those errors.
The db field for LinkedMonitors will be blank if it is not enabled.

Thanks. I've updated the offending fields with NULL
