With a new camera and/or a new location, I often will give it only a couple days, or one week at the most. I like to be sure the camera is working properly and that I have it aimed in the best way possible.
You need to have some method of viewing your pictures, you don't want to wait until you get home. So I usually bring either my laptop or an iPad. You may find that the sun isn't right for part of the day. Or that the wind comes up every afternoon, blowing grass, brush, or tree limbs, and causing your camera to take hundreds of pictures of nothing. Or it could just be that most of the animals that come by aren't centered in the pictures.
Lots of things can go wrong so the first time you check it, you may end up moving it, adjusting some of the settings, clearing obstructions out of the way, etc. that's why I don't wait long the first time. But once I become more comfortable with the setup, I will give them a minimum of two weeks. Three weeks is better, and sometimes I'll go four, but I usually don't have the patience for that.
