I'd like some advice in that area also. Maybe we should start a new thread on trail cams. I just have Stealth Cams and they seem to miss a lot of shots. I should probably play around with the delay a bit, but I've actually seen deer walk by one of the cameras, and didn't get any pix.
I have a mixed bag of cameras because I usually go for the highest rated version that happens to be on sale. I bought a Browning a couple months ago and I've been very happy with it. Easy to run and takes nice, sharp pictures. I know it picks up movement at least some of the time from a pretty good distance (30 yards) because it got me heading to my tree.
I own two Moultrie cameras I've had for probably ten years. They were originally the same model, but one leaked water, so I called the number on the box and spoke with the nicest lady with an incredible southern accent. It took just a few minutes and I had a brand new replacement heading my way. I was really happy when the replacement turned out to be a far better model than what I originally bought. They worked great for years, but they don't seem to be working as well anymore. The display on one is difficult to read and I don't think it picks up the deer as well as it used to. The picture quality on the other is fading. But, I have no complaints about the Moultries - I definitely feel like I've gotten my money's worth. My favorite camera was also a Moultrie, but a battery leaked, causing the end of the that one.
I have one Stealth camera that works well enough. It's sitting in a spot where deer walk within 10 yards because I think it was missing a lot of pictures. I had it in a tree line trying to get shots of some coyotes and it came up empty a lot while other cameras were catching them. Maybe it's just not as sensitive as some others.
I also own a Bushnell that I've had for about a dozen years. It's really basic and the picture quality isn't what the other cameras are, but it still works and it doesn't eat up a lot of battery.
