I'm running the blink XT for the ease of setup/use.
Two issues with them. One in real busy areas, you want to figure out how to run micro usb to it to save on batteries. My kid and wife like standing on the porch talking to people, so I get about 2 months out of those batteries.
Two, if you mount the camera higher, I have mine just under the porch light, it will white out people's faces. If you mount it closer to doorbell level, the faces are really clear at night. (Daytime the height doesn't matter)
The other issue is sometimes where you mount them you find out you get birds etc. I have one on the back of a little free library to get the side of my jeep and my trailer, every morning at ~6:30 am I have a bird that flips it's tail feathers in front of it, and poops across the camera. it's my alarm clock basically.
