Those are very good pictures for a economy trail cam, the biggest problem I have with my Moultrie is it taking a bazzillion pictures of nothing and needing far too much time to reset the shutter for the next shot. Battery life is good as is the range especially on night shots but I've missed good shots of following deer because of that reset thingy.
Ed as you can see from your pictures the deer and surrounding area is lit up from the glow of the IR, those LEDs glow like the end of a cigarette. I have my camera 300 yds, behind and aimed toward my house, I can see the red glow every time the Moultrie fires which is often, cause it just likes to take pictures.
I have some good shots of deer nostrils because the IR grabs their attention and they will walk right up to the camera for a better look see.
As for the rotten SOBs stealing, a second camera placed high in a tree aimed at the first camera or ladder stand will get some good pictures too.
My biggest issue with field cams, when your huntin' a strange area is, ya gotta watch were ya pee or..... sumpthin' else.
Good luck with that deer Ed, I hope he stays in the area for ya.
