Abstract
The various implementations described herein include methods, devices, and systems for illuminating and capturing scenes. In one aspect, a video camera assembly includes: (1) an image sensor having a field of view corresponding to a scene; (2) infrared illuminators to selectively illuminate the scene; and (3) a single-piece cover positioned in front of the image sensor and the illuminators such that light from the illuminators is directed through the cover and light from the scene passes through the cover prior to entering the image sensor, including: (a) a first portion corresponding to the image sensor and substantially transparent to visible light and IR light; (b) a second portion corresponding to the one or more IR illuminators and coated to be substantially transparent to IR light; and (c) a third portion between the first portion and the second portion and coated to be substantially opaque to IR and visible light.
