A slider window assembly for a vehicle includes a frame portion having an upper rail and a lower rail fixedly attached to at least one fixed window panel, with the at least one fixed window panel defining an opening. A movable window panel is movable along the upper rail and the lower rail between a closed position, where the movable window panel is disposed at the opening, and an opened position, where the movable window panel is disposed at least partially along the at least one fixed window panel. A camera is mounted at an inner surface of the at least one fixed window panel and captures image data representative of the scene rearward of the slider window assembly.
