WilCam47 is correct the biggest thing will be concealing the camera. The Covert Red40 really lights the night well also, but is a red flash. However I have noticed that unless you are looking directly at the camera you don't see it, so in a well concealed set you probably would be ok. Also the Covert Black 60 does a good job and beyond 18 inches I can't tell if the "flash" fires or not. Battery life is outstanding on both of these cameras, I get 20,000+ pics on a set of batteries.
The Moultrie does have a good flash as well and takes good quality pics.
