Solar powered camera

I'm looking into solar powered cameras (video camera or just camera-- just a camera would be preferable since I'm assuming video would be MUCH more expensive) that can connect to any type of wireless network and send me a picture. It doesn't have to be a good camera, all I need to beable to tell is if it's a human or not. List anything you can find/know of preferably starting in the cheaper range. What are the setbacks to a system like this? Thanks.

n0b0dy? I've found some video ones online for about 4,000-6,000. Too spendy for me at the moment, anyone know of any cheaper ones or is it just not happenin

how about one of those cams hunters leave in the woods?
