Game cameras, also called trail or scouting cameras are a relatively new item in the outdoors retail market. It's a simple concept. Put a camera on a tree and take pictures of things that walk by, whether it's game, or poachers, or whatever it might be. It's a form of outdoor photography that's fairly new and fairly basic.
Some folks say that the flash of the camera disturbs the game and old Mossy-horn won't get caught by that trick twice. Other folks say that the flash doesn't bother game. Some cameras use infrared light to take nighttime photos. The claim is made that the infrared flash doesn't disturb the game.
Everything that I've read suggests to me that game can't see infrared light any better than we can, so the camera shouldn't spook anything moving about at night.
Today I was walking through Academy Sports and Outdoors and saw a camera that caught my eye. The Wildview TGL3IR Game Camera. It's an entry-level game camera that has an IR emitter for nighttime use.
I bought the thing and I've played with it enough in the backyard that I'm comfortable with the way it works. I think I'm going to put it at Momma's place overlooking a feeder and see if I can catch any pics of animals using the feeder. It ought to be an interesting experiment.
