I had person detection associated with my CMC camera which was labelled Parking Lot. that V2 camera had been working perfectly well for more than one year. Today I noticed it went offline and I was unable to reset it or reinstall it so I filed a ticket. I am pretty sure that camera is dead. I took a camera from a different location, and renamed it as Parking Lot LR3 and made it my CMC camera and it works fine.
what strikes me as odd is that now when I go to associate parking lot lr3 with person detection that camera is not listed.
