A lot of people have been able to set them up. It is a little bit of trial and error to get the best out of them,
you already have been doing that. With the right camera, it is a lot easier.
I have a pole barn with hay, straw, and grain that likes to attract mice and rats. I never had a problem in 20+ years,
until last year. I had a batch of pack rats come in and tear everything up. With my cameras up at 8 foot, you could see
dozens of pairs of eyes bouncing around at night. I ended up putting 2 types of traps, and 2 types of poison out.
After about 3 months of removing carcasses, the problem finally came to an end. The rats were half the size of my cats!
Good luck with your problem.
