...a bunch of us that went to the Ubiquiti conference in Chicago, IL got a free cam just for attending. Mounting in a ceiling tile is super easy with the large plastic nut. I have not tried any of their other cameras (yet). Realize that their POE is not the standard 802.3af/at but a proprietary POE midspan power supply which is included in the box.
They also announced there would be another outdoor/weatherproof model with IR LEDs coming soon.
They showed off their software, which runs on Windows and *nix, entirely a browser-based interface; it does motion detection, but not people detection like VDV, on an i7 they said it should support 10 cameras at around 25fps each - not sure what resolution, nor sure that I believe it. They said in future versions they will be offloading the motion detection part to the camera processor itself, so the stream to the server isn't constant, also support for recording to the memory card in the camera.
If you are after "Vandal Proof Housing Waterproof , Professional Outdoor Dome" you should be looking at Axis, all of their cams will work with VDV. See:
