Yah my bike GPS alarm arms when I walk 15 feet away and disarm when I’m next to the bike really helps keep it safe, having same with the camera system would make it really easy then I wouldn’t have to arm disarm everything I’m home. Finicking with phone or if phone is dead there is the pin pad but every day I’d rather it just auto switch .

The lack of fob is the only reason everything in my house isn’t Wyze. sad
It’s probably possible with Home Assistant and a third party device. I have some YoLink fobs that work with HA. I use them for a routine that turns off several Wyze bulbs at bedtime. I don’t have Home Monitoring so I can’t test.
