A protective photographic system includng a low cost still camera mounted in a concealing enclosure and having a mechanism driven by an electric motor unit for automatically advancing a film winding lever of the camera and depressing an exposure button of the camera at a predetermined rate in response to a control unit electrically connected to the electric motor unit. The mechanism is mounted on an exposure button collar rigidly attached to a surface of the camera. The mechanism includes a reciprocating plate having a perpendicularly extending member for engaging the film winding lever. The reciprocating member rotates counterclockwise through an angle sufficient to advance the film winding lever to a predetermined position and then rotates counterclockwise to allow the film winding lever to return to an initial position. The rotation of the reciprocating member in the counterclockwise and clockwise directions occurs in response to a rotating crank member coupled to a rotating shaft of the electric motor unit. A button depressing member depresses the exposure button during predetermined portion of the counterclockwise rotation.
