I was lucky enough to get a new toy for Christmas. It's a 2.4Ghz wireless camera and 2.5" LCD monitor system designed to see behind you in a car. You can see it here:

Here's the Monitor:
And the Camera:
I'm not going to put in in the car. Actually there's a number of things I want to try. Number 1 is a dog-cam for Dinky's collar (our blue heeler mix). :-)
In any case, I was thinking: The camera is reasonably weatherproof. It's designed to be mounted on a license plate frame after all. It draws about 70ma and can be run on 9vdc as well as the 12v it's designed for. I've tested it to over 100 feet and it works well.
This would be really cool to have attached to a windmill head facing the stator and/or furling joint. It seems like it could be powered from the mill itself or even a small solar panel. The camera module itself is about 1.5 X 2 inches. The little wings on the side can be cut off. This would seem a good way to look for icing or even view a thermometer embedded in the stator. For that matter it would provide a neat fish eye view of the world.
Inside the monitor itself is a clearly marked test point labeled "VIDEO". I've already verified that this is a standard video line signal that can be connected directly to a VCR, TV, etc. if you want to record or have a larger monitor.
I'm still hacking on mine if you have any questions.
