The mechanism which allows the lens cover to be secured to and removed from the camera includes a set of wires embedded into the lens cover and a set of wedges protruding from the lens wall of the camera. To secure the lens cover to the camera, the lens cover is placed onto the front of the camera and rotated until the wires align with corresponding wedges, securing the wires underneath the tapered surface of the wedges. To remove the lens cover from the camera, a force is applied outward and normal to the lens cover, causing the wires to flex outward and enabling the rotation and removal of the lens cover from the camera.
