I am a retired sys admin and I more time then money. I have always wanted to set up monitors/cameras in and around my house. Is it possible to construct devices that using Arduino boards with various sensors send numeric/video data back to a central point via wireless transmission (Xbee)? My main concern is power; most of the places I want to monitor would have to be either battery or solar powered. Some units would have to be weather proof also, being outside many yards from the base.
I would reassurance before I start down this trail, that the technology using Arduino gear will work.
