3) contact sensors- people complain they are too large-this is true if you plan to use on windows and most your openings, but thats true for any system that is not hard wired, including Nest ‘s contact sensors which are much more $ and only slightly smaller . And the hard wired ones are set into window/door frame- you can do that yourself and hire at least Hal;f the senior (i have chosen to embed with a little chiseling the large part fo the contact and lead the mangnet small part episode on the door; if you want it save yourself soem work and can tolerate a little more obvious appearances, embed the magnet. If this is a big issue for anyoen, just embed one half fo the contact into the doorframe it yield a very unobtrusive appearance.
Biggest problem though is the ‘wake up’ time. You reported on it, but I didn’t really take the time to really consider, “Hey, if I want to catch the kids driving by banging mailboxes, by the time they drive by and the camera wakes up, they’re gone!’ Well, that’s just what I learned as I set everything up, had the ap working and started getting notifications when people drove by. I thought AWESOME! it works! Well, not so much. Unfortunately, the car is never seen on the video, so the purpose is pretty much defeated.
The door/window sensors (also called contact sensors) work pretty well, but the same cannot be said about the motion sensors; they will detect motion after there’s been plenty of movement (if I walk the hallway and enter a room it will not detect, but if I sit for a few seconds moving in the hallway it will detect it then). This is still not a show stopper for me, as I have a dog and don’t plan on buying any more motion sensors, it will be all contact sensors.
It was 20*F outside when I installed the cam. I didn't want to be running up and down a ladder if I had problems connecting to the network. I wired the cam up with a plug (from an old, grounded extension cord) and ran the wifi setup routine at my kitchen table. I verified everything was working (including the app, motion detection, etc.) before I installed it outside.
