Abstract
In general, one aspect of the subject matter described in this specification can be embodied in an anti-fogging apparatus for a camera assembly. The anti-fogging apparatus includes a camera affixed to a substrate, and a thermally conductive plate, the thermally conductive plate positioned in front of the substrate and defining a first aperture aligned with a lens of the camera. The anti-fogging apparatus includes a transparent plate positioned in front of the thermally conductive plate such that the transparent plate covers said first aperture. The anti-fogging apparatus includes an insulating element positioned in front of the transparent plate and defining a second aperture aligned with the first aperture. The anti-fogging apparatus includes a heating element affixed to the thermally conductive plate. The anti-fogging apparatus includes a case enclosing the camera, the thermally conductive plate, the transparent plate, the insulating element, and the heating element.
