Abstract
A camera assembly includes an image sensor having a field of view corresponding to a scene, an infrared (IR) illuminator configured to selectively illuminate the scene, and a single-piece cover element positioned in front of the image sensor and the IR illuminator such that light from the IR illuminator is directed through the cover element along a first light path and light from the scene passes through the cover element along a second light path prior to entering the image sensor, the cover element including a first portion between the first light path and the second light path, the first portion being substantially opaque to IR and/or visible light.

A camera assembly, comprising:
- an image sensor having a field of view corresponding to a scene;
- an infrared (IR) illuminator configured to selectively illuminate the scene;
- and
- a single-piece cover element positioned in front of the image sensor and the IR illuminator such that light from the IR illuminator is directed through the cover element along a first light path and light from the scene passes through the cover element along a second light path prior to entering the image sensor, the cover element having multiple portions including:
- a first portion corresponding to the first light path and having a first light transmission property;
- a second portion corresponding to the second light path and having a second light transmission property that is different from the first light transmission property;
- and
- a third portion separating the first portion from the second portion, the third portion being between the first light path and the second light path and being substantially opaque to at least one of IR light or visible light.
