I can't believe nobody has replied
A fella about a mile from me installed a couple in the trees around his new house in the middle of nowhere. Sure enough, somebody got wind of the new house and took a katy bar to his door one day. The cameras did their job nicely. Said owner printed out the pix and posted them predominately around the neighborhood. Literally 8x11 (B/W) glossy photos with circles and... Cops couldn't really do anything as the photos didn't 'catch anyone in the act'.
That said, get inexpensive ones, make sure they're camo of some sort. As if anybody sees them, they'll probably get damaged.
Color pix are nice bling, but 'color photos' do not work well at night... even w/ infrared LED's. Set one up to take pix of approaching/departing license plates. And do notify your homies you may have hidden cameras around your perimeter.
