Let me give you some advice. I've tested several of these cameras and here is MY honest opinion.
First off if you are going to put a camera on a feeder and or a spot where the animal will stop, then any of the cameras will work fine. The problem is when you want to put them on walking trails. Now, I've pulled some cards and had no missed pics and I've pulled some cards and have missed a bunch. The problem is in the trigger. When not in use the cameras go into sleep mode. It takes something to trigger them out of sleep mode. If you have a deer walk faast through the zone, you may only get the butt end. It seems the colder it gets, the slower the triggers work. Lately I've been using the Cuddeback IR. It works pretty good but I still miss pics. I don't do feeders so trails is all I use it on. This is a $450.00 camera and is not perfect by any means. Appears to be the fastest trigger I've found but still not perfect. Lately I've been looking into "homebrews" cameras. (homemade cameras) They have by far the fastest trigger speeds because they have no sleep mode. Problem with them is battery life and if a flock of turkeys get in front of it, the camera will keep snapping pics until the memory card fills up. Doesn't miss any pics though. So if you were not confused before, I hope I really confused you now
No really, look at what application your looking to use it for and buy accordingly. If using it for trails, try to place it in a spot where the deer have to stop or at least slow down. Good Luck!
