This past year was the first for me with digital game cams. I used cams before back when they were regular film.
I got into it in a BIG way - have 10 cams now and I put them up everywhere, from the lease to security at my coast house.
My experience has been varied. I have Moultrie, Bushnell, and WGI. I have come to the conclusion that there each and every camera is different, regardless of model/manufactorer.
Within the same model/manufactor, I have some that work great and have had zero issues. Others that never did work right. And some that were cr-p, then suddenly started working great. Others that worked great then suddenly starting having issues.
Some work better in winter, and have real problems in our 110 deg heat this past summer. Others that worked fine in the summer and take miss pictures when it got cooler.
It just seems to be hit and miss.
One interesting thing about running a lot of cams that I discovered. I put two on one feeder on opposite side. VERY often one cam would catch an animal and the other wouldn't take a single picture during the same time period. If I was using just one cam, I would have never seen the deer!
I have cams at the feeders, at the stand, and spread out over travel areas. Having a lot of cams has really shown me how the animals approach and move through the area. Also shows who is coming to my stand when I am not there.
I'll move the cams around from time to time. You'd be surprised (or maybe not) to find that some of the biggest deer may approach and hang around your area, but never actually come to your feeder.
I love cams now. To me, it's hunting without pulling the trigger. I get a lot of enjoyment of running the cams and seeing and getting to know what critters live around the lease. I get excited and a rush traveling to the lease just to pull the cards and see what I can see.
And still with all the cams, I've had animals show up while sitting that I NEVER saw before or since on cam.
