Blue Iris

Ive been running BI5 for a couple years now, with 2 cameras attached via poe switch issue free. Out of the blue yesterday, my front camera will no longer trigger in BlueIris. Its recording, video is working just wont trigger on motion. I didnt touch a thing for settings, thats what has me puzzled. I compared all my settings against my back yard camera (triggers still working) and everything is still identical as it should be I didnt change anything. Ive rebooted the Pc running BI, rebooted cameras and the poe switch. Im at a lost as to where to go now.Any help very much appreciated, thanks.

Delete the camera and install it again. Use the same name, etc. to maintain the storage association.

Another experiment/test would be to just clone the camera to see if triggers work with the clone.

So I went on the PC to try cloning the camera. And I went through all my settings again, and noticed the problem. In my zones where you highlight the trigger area, for some reason nothing was highlighted. Everything is working good again. I dont understand why though, I wasnt on that pc at all yesterday when It stopped triggering. I came off night shift and was sleeping all day. super strange. Thank you so much for the reply, much appreciated
