I'm experimenting with WiFi cameras and just got one. They are totally incredible - the Foscam Fl8918W is the one I'm playing with: - costs under $60 - has full tilt/swivel - allows any number of viewers (web server, iOS, Android) - works great to view with phones or tablets - apps are all free for viewing although there are some more advanced apps for a few dollars that I haven't tried too - allows remote viewing with an internet connection (you need to know how to do port forwarding and need a router) - has a built-in IR mode that can automatically turn on for low light conditions - consumes 3.4 watts - has modes to flip and invert so it can hang upside down or provide a backward view and flip the image so to not confuse someone looking at it foward ...and on and on. I'm going to get 3 more of them. They are great in for the engine room too. I just set it up with total darkness in the engine room and it gave a great IR-enhanced image, plenty good enough to read gauges, etc. It consumes 5.2 watts when it's totally dark and using the IR mode. I'm going to eventually write an article about the whole thing. If I get a moment tonight, I'll post some screen shots of what it all looks like. It's full screen on the iPad providing a very nice live video feed. We're about to jump offshore, overnight and I'm going to try it in the engine room with all lights while underway out to see how well it works in a real engine room environment. Anyway, Bluetooth isn't the way to do this. WiFi is...
