We bought 2 Wildgame cameras right after Christmas. Love the pics and the videos they take. We weren't trying to watch for critters getting to the chickens as they are well protected by their enclosure. As someone mentioned before, it's the 2 legged critters we are looking for. Put one camera where it takes videos of who comes and goes on our driveway. It's infrared so there's now bright flash to alert someone that it's there.
Also have a Cuddyback cam at the other end of our property. It takes good night pics as well, but isn't infrared so there is a bright flash. Doesn't seem to bother the animals though. At least the 12 point buck didn't mind. LOL
