A motion detector camera includes a camera mechanism mounted inside a housing, a motion detector exposed on a surface of the housing, and a controller for controlling the camera mechanism in response to signals received from the motion detector. The camera can include an activity counter mounted to the housing. The controller activates the camera mechanism when the controller receives a triggering signal from the motion detector, or the controller activates the activity counter and does not activate the camera mechanism when a triggering activity occurs. The camera can include digital camera electronics. A camera support can be used to removably mount the camera to an object such as a tree.
