Summary: I am in charge of installing cameras in multiple buildings on my WAN. I used "better" cameras in the first building due to the need for high-quality video if anything were ever to happen there.
Pros: Easily blends in by looking like a smoke detector --- can take the place of 4 cameras --- easy to setup --- better low-light image than a similar, but more expensive camera I've used
Cons: No Power Over Ethernet --- Only records the video the way that it is configured as opposed to being able to Pan/Tilt/Zoom once it's been recorded --- no software in the box and the downloadable software is useless in a server/monitor situation --- IR lights for night vision?
Summary: I bought 2 of those cams for a client you wanted wireless security cameras. To be honest, they work better than I thought; normally I stay away from Dlink products because I had a couple of bad experience with them, but those cams seems to be the exception.
