Backup Camera - Variations

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.
• Backup or Reversing Cameras can be added as aftermarket additions to vehicles that do not come with factory-fitted systems. They are available in both wired and wireless versions.
• Backup or Rear-Camera Displays in the Rearview mirror can be used in vehicles to detect activity behind the car to "avoid the tooling, software, hardware, and testing costs associated with integrating the display/feature in other areas of the vehicle."
