This camera has a very nice picture, only drawback is it has a small field of view.
I replaced a cheap plastic model that had a very wide field of my front porch. When I put this in the same location, it barely showed anything, so I had to move it 15 feet away to see the area I wanted.
However, that far away made identifying people difficult unless you knew them. Not sure if an ID could be made from a screen capture from that distance.
To get a good face shot, you'd have to mount it so low it could easily be stolen.
I bought 4 of these, one has a halo around the frame when the IR is on. Annoying but acceptable.
The IR works great, one on my driveway can see over 50 feet to my neighbors steps. The one in my backyard shows almost the entire 40 X 60 lot.
Not sure about the weatherability, it says it is NOT waterproof and not to mount it where it can get rained on. Finding a place out of direct rain may be hard and might not suit your apps.
All in all, this is a very good bargain...BUT,
If you need multiple cams, buy one to see if the view is what you want.
