1. A trail camera comprising: a lens; a passive infrared motion sensor; a flash; a controller; and a hardware storage device configured to store pictures or video, wherein the controller is configured to: detect conditions at the trail camera, including at least a remaining storage capacity of the hardware storage device; when the remaining storage capacity of the hardware storage device exceeds a specified capacity threshold, configure the passive infrared motion sensor in a first sensitivity setting where the passive infrared motion sensor triggers the controller to cause the trail camera to perform image capture; and when the remaining storage capacity of the hardware storage device falls below the specified capacity threshold, configure the passive infrared motion sensor in a second sensitivity setting that is relatively less sensitive than the first sensitivity setting, wherein the passive infrared motion sensor continues to trigger the controller to cause the trail camera to perform image capture in the second sensitivity setting.
