I have a newer Moultrie 100 and while I do have a lot of pictures of pigs, they have to step right in front of it to get the camera to go off. If something walks say 6-7 feet out in front of it then no picture. I have it sitting in front of a feeder right now and you can look at the ground and see that there has been a lot of activity at the feeder, but no pictures. Now to be fair, the pictures that it has taken have been pretty good and I easily get 2-3 weeks out of the rechargeable Moultrie 6v battery. I will have to see how that life stacks up once the cool weather hits here in Texas as I have only had it about three months.
