National Geographic photographer Michael Nichols uses highly specialized remote-camera systems to obtain remarkable images of never-before-seen wildlife behavior. Triggered by heat and movement, both the 35-mm and digital models of these simplified all-weather cameras take multiple images to capture backyard wildlife. Equipped with a wide-angle lens with 60-degree field of view and two test modes, these cameras will run for 21 days of 24-hour operation before needing fresh batteries. Approximately 5 3/4''W x 7 1/2''H x 2 1/2''D.

35-mm model (green) features a 30-foot range flash, 1- to 60-minute pause time between activations, time or date stamp, and test mode. It requires eight AA batteries, not included.
