Everyone has a rearview mirror in their car because it allows the driver to see the traffic behind them clearly and so make better decisions while driving.

However, traditional rearview mirrors, on the other hand, are limited in usefulness and have some primary problems. That’s where digital electronic rearview mirrors come in.

In this post. We’ll discuss everything you’d like to know when picking up your digital electronic rearview mirrors.

So if you want to:

  • Purchase a brand new electronic rearview mirror

  • Learn about what does an electronic rearview mirror do

  • Find out the Pros and Cons of such a system

So, let’s dive right in now.

What is Digital Electronic Rearview Mirror?

The digital display rearview mirror allows you to see through the back of your vehicle via a connected wireless or wired backup camera, keeping you secure even if your cargo space is completely full.

It functions similarly to a traditional mirror when it is not displaying a backup camera images, but by merely flicking a switch, the mirror gains an enhanced field of vision and clarity via a digital display.

Digital Rearview Mirror: What Does It Do For You?

  • The standard rearview mirror simply reflects items at the rear of the vehicle. When the cargo area is crowded with luggage or a tall passenger is in the backseat, the driver’s line of sight might easily be hindered due to the limited view.

    On the contrary, because it reflects the image from outside the car, the digital rearview mirror can handle these scenarios with ease. With the rear or side camera fitted, the digital rearview mirror will have nothing to restrict its image to the outside world, providing the driver with a wider and sharper view of the traffic conditions behind.

  • The traditional rearview mirror has a larger region of blindspots.

    Fortunately, an aftermarket digital rearview mirror may significantly reduce the number of blind spots when driving. Because camera is located above the license plate, digital rearview mirrors offer at least a 100° field of vision and have the added benefit of capturing the lower region behind the car.

    The camera vision is far lower than a standard rearview mirror, allowing the driver to see exactly where the car is backing into.

    Not to add, with a simple flick of the screen, the digital rearview mirror may be adjusted to view higher or lower, left or right. Having a better and more comprehensive perspective of what’s going on behind the car.

  • During the nighttime, the standard rearview mirror reflects the blinding beams from the headlights of vehicles behind the driver into your eyes.

    When the vehicles behind you have their high beam lights or headlights constantly shining and reflecting back at you through the rearview mirror, it is exceedingly unsafe.

    Not only may they be incredibly distracting, but they can also impact your vision.

    In this scenario, the normal rearview mirror lacks an auto-dimming feature to protect the driver’s eyes.

    The image sensor of the digital rearview mirror, on the other hand, will automatically filter out the bright light and ensure the best vision of the traffic behind.

    The digital rearview mirror simply eliminates the need to manually adjust the mirror when driving at night.

  • Traditional rearview mirrors rely significantly on clean windows to provide an optimally clear back image of the vehicle.

    That being said, if the weather outside the car turns severe, there is nothing the driver can do to improve the clarity of their vision behind the wheel.

    Rain or snow can readily accumulate on the back glass, obstructing visibility in the rearview mirror.

    Fortunately, because the camera is located outside the car rather than inside, the digital rearview mirror works in all weather conditions.

    The camera can even see through the fog with high-end heated functions. In any weather, the digital rearview mirror displays clear real-time footage of oncoming vehicles.

Disadvantages of Electronic Rearview Mirrors

Any electronic device is susceptible to malfunction, which can occur at inconvenient times. This also applies to the aftermarket digital rearview mirror.

Furthermore, auto-dimming rearview mirrors are more difficult to repair than standard rearview mirrors. Electronic rearview mirrors also take some getting used to since you will most likely want to adjust them manually at first out of habit.


The expense of cameras is one of the primary reasons why they have not yet replaced side or rear view mirrors.

Mirrors are very affordable to install, replace, and repair, but camera systems are not. Cameras raise the initial cost of a vehicle and will cost more to maintain and repair.


The digital display rearview mirror is a nice device to have in your car to improve safety and vision while driving.

This will be useful if you frequently carry a lot of items in your cargo compartment, or drive a bus at night time. Then you should select a digital rear view mirror!
