Have a good look at the Grandstream domes; think there are three models. Two are around $100 and one is more. The nicer one is IP66 rated.
The GXV3611_HD and the GXV3611_LL have the smoke detectors. They were priced the same.
1 - To reset you have to hold the reset button for 10 seconds
2 - Download the Discovery Tool utilities software
http://www.ubnt.com/downloads/discovery/ubnt-discovery_v2.2.1.zip
and run it:
You will see all of your Ubiquiti devices with it. The MAC address of your camera is on the camera and will match what the tool sees.
When I tried the utilities tool it worked fine. I was able to configure the camera just fine. When I rebooted though it would get messed up.
Takes five minutes to check.
