A backup camera (also called a reversing camera or rear-view 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, and to alleviate the rear blind spot. It is specifically designed to avoid a backup collision. The area directly behind vehicles has been described as a “killing zone” due to the associated carnage.Backup cameras are usually connected to the vehicle head unit display.
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. 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.
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 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.
360-Degree Surround View Parking Assistance System
The 360-degree full-view parking assistant system also called “Around View Monitor” or “bird view” of the vehicle,it collects the images around the vehicle through four ultra-wide-angle cameras installed around the front and rear of the vehicle body. After rectification and splicing by the image processing unit, a 360-degree panoramic view around the vehicle is formed and transmitted to the display device of the central console in real time. Through 360 full-view system, the driver can directly see the position of the vehicle and the obstacles around the vehicle while sitting in the vehicle. The driver can control the vehicle parking or passing through the complex road surface with ease, effectively reducing the occurrence of scratch, collision, subsidence and other accidents.
Wireless Backup Camera
This is an advanced type of reversing camera that does not require the use of cables between the camera itself and the display. It functions remotely. Wireless rear-view cameras usually have separate sources of power from the display. The cameras are usually powered by the same power source as the brake and thus switches on automatically when one engages the reverse gear. Majority of these backup cameras usually come with a transmitter (near the camera) and a receiver (near the display) for relaying the signals and live images. Some models such as the Pearl RearVision backup camera, which is made by Pearl Automation, use solar energy for power.The display for these types of backup camera can be powered from the cigarette socket on the car’s dashboard. Some of the displays are also integrated on the rear-view mirror thereby giving it a multipurpose function. Some models also sync directly with one’s phone using an app which then acts as the display. The main advantage of this type of backup camera is that it is extremely easy to install and rarely requires the help of professional when doing it. The installation of these cameras also do not interfere with a car’s look as minimal to no drilling or laying of wires is required. However, this comes at a cost as some of these wireless cameras are quite expensive.
Blind spot monitors
Blind spot monitors are an option that may include more than monitoring the sides of the vehicle. It can include “Cross Traffic Alert”, “which alerts drivers backing out of a parking space when traffic is approaching from the sides.
