A friend of mine has them. The one on his front porch is inside the house and you can see it pointing at you when you walk up to the front door as it has a red light on it. Plus he has a sign next to the door that says something about you being on camera. His first problem with it was the red light. At night the light shining on the glass screwed up the picute with glare. Now he has changed the setting so when it goes into night mode the light goes off. You can still see it but the sign helps. Its tied into his computer system and with motion detector too. The picture is beautiful. And for wireless they really didnt cost as much as i thought.
