Abstract
A camera system includes a body defining a cavity therein, and a camera attached to the body within the cavity and including a lens. The camera system also includes a shape memory alloy transitionable between a first state and a second state in response to a thermal activation signal, and a wiper configured for wiping debris from the lens. The wiper is attached to the camera and is actuatable by the shape memory alloy. The shape memory alloy transitions between the first state and the second state to actuate the wiper so that the wiper contacts and translates across the lens and thereby wipes debris from the lens.
