For those of you who don't know, David has been building Wildlife/wild game camera cases which he then takes and modifies a regular digital camera by hooking up things like infrared and heat sensors and the like to make the camera take pictures and short movies whenever something steps in front of it. He also camouflages them so they don't stick out either. For a quick example of how these mods look, go to SnapShotSniper.com and take a gander.
Here's what the finishing results end up looking somewhat like.
Basically, he then straps one to a tree in the woods (preferably near a drinking hole or game trail) and let's it go for a couple of weeks. After a time, he then retrieves the camera from the woods and collects the images it has taken by hooking it to his computer.
Here are a collection of images he and Madyson (father and daughter) found when they went retrieved the most recent two!
