I am holding off on updating until the first of the New Year. I want to be sure Monterey has all of the major bugs eliminated before I take the plunge. That does look promising, though. Right now, I am using Chrome to view the camera web page.
Day to day I use Synology Surveillance Station to monitor the camera, but the web interface on the camera is pretty promiscuous and will work on most browsers. ha
I haven't played with creating rules too much yet, but I should add a few more. I figured I could click away and design a zone which didn't include going through bushes and trees so I wouldn't get false alarms with winds blowing foliage but it seems I can only define a shape with 4 sides. I didn't realize that was a 4-gon conclusion
Or is because I am not using the old IE browser for my definitions. I have yet to try any of this on the old iMAC which has a Parallels Windows partition.
And unfortunately, I should update, that after my initial easy breezy success at defining that intrusion rule above, my next attempt required the repeated mouse clicks (Right) to release the green line, before I could save it. To me it's an incredibly small price to pay imho, but still.
EDIT: It's like my camera is haunted. I was able to use the newest Safari to define a new intrusion rule, and this time around I was allowed approx 20 sides to my defined area which worked great. Once it reaches that magic number of segments allowed it just joins up with the initial point I began at. It took a few attempts to nail it, but I'll test it tonight to see how it does. I'm sure there will be a few night visitors.
Here is how it looks at this point:
