backup camera (also called the reversing camera or rear view camera ) is a special type of video camera manufactured specifically for the purpose attached to the rear of the vehicle for help reserve, and to reduce the blind rear point. It's specially designed to avoid back-up collisions. The area behind the vehicle has been described as a "homicide zone" due to the associated massacre. The backup camera is usually connected to the vehicle head unit display.
The backup camera design is different from other cameras because the image is horizontally turned so that the output is a mirror image. This is necessary because the camera and driver are facing the opposite direction, and without it, the camera will be on the left of the driver and vice versa. Mirror images make the screen orientation consistent with the physical mirror mounted on the vehicle. Backup cameras typically use wide-angle or fisheye lenses. While such lenses undermine the camera's ability to view distant objects, it allows the camera to view horizontal roads uninterrupted from one back corner to the other. Cameras usually pointed at a downward angle, to see potential obstacles on the ground as well as positioning close to walls and docks, rather than straight back.
Backup cameras are commonly used on vehicles that pull trailers that are hard to see, such as a motorhome. Recently, with the increasing popularity of in-dash DVD players and GPS navigation systems that help in justifying the cost of adding color LCDs to the driver's seat, they are becoming much more common, often available as optional factory accessories on standard passenger trucks and sports vehicles, as well as aftermarket accessories. Inside the vehicle, the screen is usually transferred automatically when the transmission is set up in reverse, showing the backup view temporarily in reverse, and displaying the map (or other content) at other times.

Variations
Backup cameras are produced in various types depending on the application.
- For large vehicles such as motors, camera systems with internal servomechanisms allow the driver to shift and tilt the camera remotely.
- Integrated audio connections (one-way or two-way) are used in addition to camera systems to communicate with non-vehicle-wide reconnaissance when supporting large trailers or launching boats.
- Night vision cameras use a series of infrared lights to support in the dark, when positioning or the intensity of the vehicle's white backlight is insufficient for this purpose.
- Portable or semi-permanent all-in-one camera systems (also known as dashboard cameras or dashcams) are sold exclusively for small vehicles that are not permanently installed on the dashboard. Such a system consists of a small portable screen that hangs from the sun's shield above, and the length of the wire to reach the camera.
- The plat-frame versions allow permanent installation without permanent vehicle modification.
- Custom cameras are manufactured to fit certain brands and models of vehicles. For example, for Hummer H2, there is a special camera that replaces the tail light of the factory and in accordance with the style of the original vehicle. Another special camera replaces the brake lights with a combination device that contains the camera while it is still on as a brake light.
- Backup or Reversing Cameras can be added as an aftermarket addition to vehicles that are not equipped with factory-installed systems. They are available in both wired and wireless versions.
- Rearview Camera Backlight or View on the Rearview mirror can be used in the vehicle to detect activity behind the car to "avoid the tools, software, hardware, and testing costs associated with display integration/features in other areas of the vehicle."

Introduction
The first backup camera was used in the 1956 Buick Centurion concept car, which was presented in January 1956 at General Motors Motorama. The vehicle has a television camera mounted on the back that sends images to a TV screen on the dashboard instead of the rearview mirror.
The first production car that incorporates a spare camera is the Toyota Soarer Limited 1991 (UZZ31 and UZZ32), which is available only in Japan and not in the US, Lexus SC. The Toyota system uses a color EMV display, with a rear-spoiler-mounted CCD camera. The system was discontinued in 1997. In April 2000, Infiniti's luxury division of Nissan introduced the RearView Monitor in the 2002 Q45 flagship sedan at the 2000 New York International Exhibition. Introducing the guidelines on the colored screens as parking distance parameters, the RearView Monitor operated from a camera mounted on a plate in the trunk that transmits a mirror image to an in-dash (7-inch) LCD screen. It was available as an optional equipment at the North American market launch in March 2001. Nissan Primera 2002 introduced the RearView Monitor backup camera system to regions outside of Japan and North America. Isuzu Vehicross also debuted this option in late 2001.
Aftermarket options for cars have been available for some time. The electronics manufacturer has made several car updates available that can be installed by professionals without changing the center console of the car.

Another type of camera system can provide a more comprehensive view.
Approximately Display Monitor
In 2007 Nissan introduced their "Around View Monitor" on the Infiniti EX35 2008, which uses four cameras to provide a bird's eye view of the vehicle. Other car manufacturers have since offered a similar system. BMW introduced their competitor system called Surround View in 2009 in the F10 5 Series.
Wireless Backup Camera
It is a sophisticated retrograde camera type that does not require the use of cables between the camera itself and the screen. This works remotely. The wireless rear-view camera usually has a separate power source from the screen. The camera is usually powered by the same power source as the brakes and thus activates automatically when one of the gears is backed up. Most of these backup cameras usually come with a transmitter (near the camera) and receiver (near the screen) to deliver live signals and images. Some models like the Pearl RearVision spare camera, made by Pearl Automation, use solar energy for power. The screen for this type of backup camera can be switched on from the cigarette socket on the car dashboard. Some displays are also integrated on the rearview mirror so as to give it a multipurpose function. Some models also sync directly with a person's phone using an app that then acts as a display. The main advantage of this type of backup camera is that it is very easy to install and seldom requires professional help when doing so. Installation of this camera also does not interfere with the appearance of the car because it does not require drilling or laying the cable. However, this comes at a cost because some of these wireless cameras are quite expensive.
Blind spot monitors and other technologies
Blind spot monitors are options that may include more than side-by-side vehicle monitoring. This can include "Cross Traffic Alert", "which reminds the driver to back out of the parking lot as traffic approaches from the side."
Mandate
In the United States, the Cameron Gulbransen Children's Transport Safety Act of 2007 requires the US Department of Transportation to issue crash safety regulations within three years and requires full compliance within four years of the final decision making.
The law sets a mandatory deadline in February 2011 to issue the final rule. However, under the Obama administration, the USDOT is repeatedly given its own renewal by the deadline, claiming it requires more time analyzing the costs and benefits of the terms. In September 2013, Greg Gulbransen, the father of the law-enforced child, along with a group of consumers and advocates petitioning the Second Circuit Court of Appeals, demanded that the USDOT apply the regulation on backup cameras within 90 days. About half of 2012 model cars are equipped with backup cameras.
On March 31, 2014, four years past the deadline, the National Highway Traffic Safety Agency announced that it would require all cars sold in the United States built in early May 2018 to include a backup camera. On October 31, 2016, Transport Canada issued a similar mandate that began at the same time.
