A backup camera is a special type of video camera that is produced specifically for the purpose of being attached to the rear of a vehicle to aid in backing up.

Backup Cameras are alternatively known as 'Reversing Cameras' or 'Rear View Cameras'.

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. 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. A mirrored image makes the orientation of the display consistent with the physical mirrors installed on the vehicle.

Backup cameras are common on vehicles that tow difficult-to-see trailers, such as motorhomes. 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 display 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. 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 showing the map (or other content) at all other times.

A backup camera typically sports a wide-angle or fisheye lens. 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. 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. Wide Angle (1999) is the debut studio album by British breakbeat trance producers Hybrid, and was re-released in 2000 as a double-CD edition entitled Wider Angle. ...

Variations

Backup cameras are produced in different varieties depending on the application.

• For large vehicles such as motorhomes, camera systems with built-in servomechanisms allow the driver to remotely pan and tilt the camera.
• Built-in audio intercoms (one-way or two-way) are used in addition to the camera system for communicating with a spotter outside the vehicle - common when backing large trailers or launching boats.
• Night vision cameras use a series of infrared lights for backing in the dark, when the positioning or the intensity of the vehicle's white reverse lights are insufficient for this purpose.
• Portable or semi-permanent all-in-one camera systems are sold typically for small vehicles that don't have displays permanently installed in the dash. Such systems consist of a small portable screen that hangs from the sun visor above, and a length of wire to reach the cameras.
• License-plate-frame versions permit permanent installation without any permanent vehicle modifications.
• Custom cameras are produced to fit specific makes and models of vehicles. For example, for the Hummer H2, a specialized camera exists that replaces a factory tail light and matches the original vehicle style. Other custom cameras replace a brake light with a combination device that contains a camera while still illuminating as a brake light.
