A lightbar for an emergency vehicle is provided. The lightbar includes lights and a camera within the same unit. An opaque and hollow cylindrical tube runs from the lens of the camera to an inside surface of the lightbar. The tube prevents IR light that reflects from the inside surface of the lightbar from entering the lens. The tube also prevents IR light and light from LED lights within the lightbar from entering the lens directly. Settings on the camera are set so that image capture is filtered at a frequency of 50 Hz and 60 Hz. By providing such a tube and by filtering out image capture at 50 Hz and 60 Hz, images captured by the camera are greatly improved in quality.
