Types of Car Rear Cameras

Also known as backup cameras or reversing cameras, car rear cameras have become essential safety features in modern vehicles. They allow drivers to see what is behind their vehicles when reversing, helping to prevent accidents and injuries. This technology uses a small wide-angle lens camera mounted on the rear of the car to display a video feed on a screen in the car. These cameras come in different types depending on design and functionality.

• CCD (Charge-Coupled Device) Rear Cameras: These car rear cameras have a higher price point but offer better image quality than their CMOS counterparts. They are considered the standard for most luxury and high-end vehicles. CCD rear cameras capture more light, making them ideal for low-light conditions. They also have a greater dynamic range, allowing them to display clearer images even when the background and foreground have different light levels.
• CMOS (Complementary Metal-Oxide-Semiconductor) Rear Cameras: As mentioned earlier, these are cheaper than CCD rear cameras, but they do not compromise much on image quality. They may have slightly poorer image quality and lower sensitivity to light. Because of their lower image quality, they are mainly used in entry-level or budget cars. Besides being used in cars, these cameras are also used in mobile phones and tablets for video calls and selfies.
• Wide-Angle Rear Cameras: Most car rear cameras use wide-angle lenses to offer a broader view of the area behind the car. However, this comes at the expense of image detail because objects in the distance appear smaller on the display screen. This is not a big deal for nearby objects, but it can be problematic for rear pedestrians who are not visible through the wider view. To counter this problem, some manufacturers produce ultra-wide-angle lenses. These lenses provide an even wider view, ensuring all objects, including those in the distance, are visible on the screen.
• Wireless Rear Cameras: Traditionally, the connection between the rear camera and the display screen in the car was done using cables. This posed installation challenges, especially in older cars without built-in rear cameras. Wireless rear cameras eliminate this problem by using radio frequencies to transmit the video signal. Not only are these cameras easy to install, but they also improve the overall look of the car by reducing visible wiring. However, wireless rear cameras are more expensive than their wired counterparts.
