I run close to 20 cameras for my bear and hog hunting and also for deer. With those numbers I have to get a camera that will provide decent battery life and not break the bank. I really don't care about picture quality in that I just need to see what is happening and not have a photo to frame. I have had great success with the Moultrie model A-5.
It is a solid performer and I have been running them for two years. In my experience many game cameras die at the 12-16 month period of service.
I don't have time for complicated set-up and I can fully program the A-5 in under a minute. I keep them in video mode and the A-5 does something that is critically important while in the video mode. It snaps a photo at the start of the video. This is HUGE when reviewing camera footage on bear and hog baits where there are several hundred video clips per camera. I can do a rapid scan of the photos and decide which videos I need to review. This saves me a tremendous amount of time vs reviewing hundreds of videos.
I buy them in bulk of the big auction site for around $55 each and that includes a 2mp card. If you can find a place called vminnovations, buy from them as they double the manufacturers warranty.
A quick word about normal I.R. cameras vs. white flash cameras. I have conducted extensive research on animal reactions to these two types of cameras and I can say without a moments hesitation that white flash cameras are far superior to normal I.R. cameras when it comes to NOT spooking game.
We run two cameras in many set ups and have this documents more times than I can remember. The white flash cameras have no impact whatsoever but the normal I.R. can cause explosive reactions from the animals. This is especially true on mature whitetails.
Blackout I.R. would be the first choice in a camera but they are costly
Here is a little video that helps to illustrate the point of white flash impact.
Hope this helped some.
