Abstract
A camera includes a housing, a light source positioned within the housing, and a light-refracting apparatus. The light-refracting apparatus comprises a collimator shaped to collimate light emitted by the light source, and a lens comprising an at least partially concave light-emitting surface positioned to receive light collimated by the collimator and shaped to disperse the collimated light. The light-refracting apparatus is arranged to cause the dispersed light to be transmitted from within the housing into a field of view region of the camera.
