Cabin monitoring system for a vehicle
A cabin monitoring system for a vehicle includes a video display screen disposed in a cabin of the vehicle so as to be viewable by a driver of the vehicle. A camera assembly is disposed at a ceiling of the cabin of the vehicle and includes a camera having an imager and a lens, with the camera having a field of view that encompasses a rear seat area of the vehicle. An illumination device is operable to illuminate the rear seat area encompassed by the field of view of the camera. The illumination device, when operated, illuminates the rear seat area and the camera captures image data representative of the illuminated rear seat area. The image data captured by the camera is provided to the video display screen for displaying video images for viewing by the driver of the vehicle.
