I have three different game camera's
Wildgame model N6C 6.0 megapixels. Runs on four C batteries and has a active day or night setting. (Not the best on battery life)
Bushnell 5.0 megapixels. Runs on four AAA batteries, no day/night setting. Better battery life then the one above.
My third camera is another Bushnell 5.0 megapixels that runs on eight AAA batteries, no day/night. This camera has the best battery life. I don't think I've replaced them in 9 months.
All the cameras have a decent quality pic, the deciding factor when purchasing one of these cameras seems to be the more batteries the better. All the camera's can be connected to a battery pack for longer life.
