1 of my cameras did because some weed grew up a few inches in front of it. I mount them about 1-3 off the ground don't have too many blank pics, unless there is storm. I've had a Moultrie DGSI40 that takes 6 D cells and has been in the woods for 5 years non-stop in a bear box. Batteries will last about 3 months when taking 3 stills at a time. Bugs got it in this last time and got bug gunk inside the lens that flips down for day shots and I have to take it apart to clean but it's been solid. The other setups are a Moultrie Game Spy M80xt, Moultrie digital game solar power panel, Master lock Python cable, and Moultrie Bear Security box. They say battery life is 1 year, it takes AA's, battery life is BS, maybe if it only takes 300 pictures. Which is why I got the solar panels with a built in battery. You can run the cams soley on the solar battery or put the aa's in it also and it will kick to the aa's if at night the cam goes nuts and runs out of the solar battery. The solar panels save a ton of money on batteries and I don't have to worry about the camera's dying and could leave them out for a year if I wanted to. Only draw back is it's kinda hard to thieve proof them, but you can mount them high in a tree since they have really long cable.
