I think some have terminals inside and you can actually use with contacts. Go Control (Linear) PIR was one where I saw that before I think. Been a long time since I had one of those.
I've just installed a Wyze cam, but tonight found that snow is problem for false motion events, so I may convert a motion sensor to run off the same supply power to the camera. Not sure that will work as well though, since Wyze seems to always record and then just save the clip on motion detection so they can give you a few seconds before motion was detected so you don't miss anything.
I have a doorbell button on order and I'm going to use that for notifications. Kind of a budget Ring doorbell, but in the style I want, instead of a box that wouldn't fit right anyway. If I had a spare motion sensor with connection points inside, that's what I would use it for. Since I don't, I ordered a contact sensor for the job, which is a sure thing even if it doesn't have terminals inside. You just solder to the reed switch. Should be able to do whatever I want without too many restrictions.
