For large vehicles such as motorhomes, camera systems with built-in servomechanisms allow the driver to remotely pan and tilt the camera.They are available in both wired and wireless versions. Backup or Reversing Cameras can be added as aftermarket additions to vehicles that do not come with factory-fitted systems.
The display will typically show the map (or other standard content) on the screen in all other gear modes in most cars.īackup cameras are produced in different varieties depending on the application. Inside the vehicle, the display is typically wired to automatically sense when the transmission is set in reverse, showing the backup view while in reverse and or providing grid guidelines by detecting the parking lot markings to aid the driver. Recently, with the rise in popularity of in-dash DVD players and GPS navigation systems which aid in justifying the expense of adding a color LCD to the driver's seat, they have become much more common, often available as optional factory accessories on standard passenger trucks and sport utility vehicles, as well as aftermarket accessories. The camera is typically pointed on a downward angle, to view potential obstacles on the ground as well as the position of approaching walls and docks, rather than straight back.īackup cameras are common on vehicles that tow difficult-to-see trailers, such as motorhomes. While such a lens spoils the camera's ability to see faraway objects, it allows the camera to see an uninterrupted horizontal path from one rear corner to the other.
A backup camera typically sports a wide-angle or fisheye lens. A mirrored image makes the orientation of the display consistent with the physical mirrors installed on the vehicle. This is necessary because the camera and the driver face opposite directions, and without it, the camera's right would be on the driver's left and vice versa. The design of a backup camera is distinct from other cameras in that the image is horizontally flipped so that the output is a mirror image.
