The critter cam is a device made by Trail Master which includes an infrared detector and a film camera trigger. The detector is strapped to the base of the tree. As animals walk by the device, it triggers the camera to take a picture. We have shortened the collection to some of the better shots. A few of the newer ones are taken by a digital unit called the Yeti-cam. This custom unit was put together by the Snow Leopard Conservancy for tracking leopards in the Himalayas.
