I keep replacing trail cams that don't work and getting ones that promise cellular communication and all sorts of things and they all work for about a week (...ok...maybe three months...

When somebody shot several rounds through the front door of our house (coincidentally right after I had terminated a patient for narcotics abuse), the police brought out cameras the size of a Mini Mag flashlight that they could half bury in the ground or tape to a tree, and similar sized motion detectors they could bury that would activate them. The batteries lasted almost a month, and the cameras took reliable pictures.
But everything they sell at Cabela's and Bass Pro and Midway USA pretty much seems to suck. Does anybody have any experience with trail cameras that actually work more than a few days and are reliable?
I know humans can be flawed but I expect machines to function perfectly 100% of the time or they get the bullet treatment. And yes, that means over the years I've shot quite a few lawn mowers, computers, cell phones, and other things that proved disappointing; I almost shot my 1968 Ford, but it was in the middle of a busy intersection and I thought I would get in trouble.. However on the upside it helps my marksmanship skills and it's quite emotionally satisfying.
