Vehicle Reversing Cameras
Why Use Vehicle Reversing Cameras?
Reversing cameras, also known as rearview cameras, make it much safer for cars to go in reverse as they provide a clear view of what is behind the vehicle, eliminating a blind spot. Their application became a necessity going as far back as the 1970s but, back then, they were mostly used for large machinery such as dump trucks and bulldozers where the driver had little to no visibility behind his vehicle. Since then, it took a few decades, but the technology has made its way to commercial cars, as well.
How Do They Work?
Rearview cameras are pretty easy to install and to operate and they are even available as aftermarket components which drivers can mount themselves. There are three major components to a rearview camera: there is the camera itself which is mounted at the rear end of the car, usually above the bumper, there is a transmitter which receives the signal from the camera and sends it to the third component, a rearview mirror with an integrated screen. This allows the driver to see everything that is happening behind him. These cameras are often paired with other technologies such as backup sensors which use proximity alarms to alert the driver when there is some obstacle in his immediate vicinity.
Benefits of a Rearview Camera
The presence of a rearview camera significantly increases the awareness of the driver. The biggest danger eliminated by the camera is running something over. Usually it is something which is low to the ground which the driver cannot normally see, even if he turns around.
The rearview camera is also designed to not cause any distractions when it is not needed. Since the integrated screen takes up about half the rearview mirror, it would be distressing to see it while driving normally and that is why these cameras are only activated when the car shifts into reverse.
Future of Reversing Cameras
A significant improvement over the traditional reversing camera already exists and that is the 360-degree camera system. This system uses a multitude of cameras – usually four, one for each side – in order to provide the driver with a complete 360-degree view of everything that is happening around him. Since such a system requires a bigger image, it is normally used with an LCD screen mounted in the center console, not an integrated screen incorporated into the rearview mirror. Even so, the principle is still the same and this new system will be adopted by more and more new models.
