The dash cam market is booming in popularity and for a good reason. With the ability to have video evidence in the event of an accident, who wouldn’t want one?

Little do most people know that dash cams offer even more advantages. For example, they are giving you assistance while parking and keeping an eye on other people driving your vehicle.

However, when it comes to deciding between a single vs dual dash cam, there are plenty of things to consider. Hence, in this guide, we’ll discuss the pros and cons of each to help you make the right choice.

The Advantages of Single Dash Cams

The most notable benefits of a single dash cam include:


Single dash cams are typically less expensive than their dual counterparts. This is because instead of requiring two cameras, they only require one.

If you’re on a budget, opting for a single model is ideal. Also, even if you’re a beginner, you may find that starting with a single camera is preferable.

Easy Installation

The majority of single dash cams give you an even easier time while installing. This is because you don’t have to worry about running wires from one camera to another. Most models require you to simply plug the camera in and mount it on your dash or your windshield.

Higher Quality Video

With a single dash cam, you will have access to a higher quality video. This is because manufacturers only need to worry about one camera lens and components.

All of the wires will be dedicated to a single camera, so you’ll have a higher resolution video or photo. This is ideal for people who want to capture important events and license plates.

The Disadvantages of Single Dash Cams

When discussing whether to choose a single vs dual dash cam, consider these disadvantages:

Only Frontal Recordings

The main disadvantage to a single dash cam is that you’ll only be able to record movement in front of your vehicle. This is convenient in the event that you rear-end someone, or someone backs up into you.

However, it doesn’t do you much good if you’re the person rear-ended. In some cases, drivers find that frontal recordings are ideal, but it’s recommended that you protect the entirety of your vehicle.

Poor Parking Coverage

One of the most substantial selling points of dash cameras is to keep an eye on your vehicle while it’s parked. Unfortunately, with a front-facing camera, you won’t be able to see a lot of activity. That is unless it occurs right in front of your vehicle.

These cameras try to offer as wide of a field of view as possible, but they still fall short when compared to dual models.

The Advantages of Dual Dash Cams

The most impressive benefits of dual dash cams include:

Superior Vehicle Coverage

With the ability to record activities around the front and back of your vehicle, you’ll be fully protected. In fact, the majority of dual dash cams work together to give you a 360-degree field of view around your entire car or truck.

You won’t have to worry about someone slashing your tires and not being caught. You’ll also be able to capture any evidence of someone rear-ending you while on the road.

Discreet Installation

It’s tough to hide a single front-facing dash cam, but hiding a rear-facing one is more straightforward. Some models can be attached to your rear bumper directly and hidden perfectly.

That gives you the ability to capture criminal acts more secretly. It’s likely they’ll see your front dash cam, but they certainly won’t know that you have one in the back as well.

Parking Assistance

Another huge advantage to dual dash cams is that they offer help when it comes to parking. Similar to any other backup camera, your dash cam can act as a guide when backing into a parking spot.

The majority of these cameras will automatically turn on when you put your vehicle in reverse. You’ll then be able to use an internal screen to monitor how you park to make the task far simpler.

The Disadvantages of Dual Dash Cams

Similar to single models, there are disadvantages to dual dash cams as well, and they are:

Back Windshield Tinting

The vast majority of modern vehicles offer some type of tinting on the back windshield. Depending on the type of rear-facing camera you choose, this could prove to be an issue, especially in poor light.

If your rear camera is installed inside of your vehicle, it will have to work against the tinting to capture clear images. Unfortunately, this can lead to many issues when recording important information.

Poor Video Quality

To help keep the cost of dual dashcams at a high yet reasonable level, the rear camera will have poorer quality. In fact, the majority of dual cameras feature a 1080p resolution in the front and a 720p resolution in the back. This means, you’ll surely have coverage in the rear of your vehicle, but it won’t be as crisp and clear as the front-facing camera.

That may lead you down the path of installing two separate cameras and networking them together. However, this is going to cost you substantially more if you were to simply buy a two-in-one package.

A More In-Depth Installation

As you’ll be responsible for installing two cameras together, it’s going to take longer than with a single camera. In fact, unless you know how to hardwire things to your car (for hardwired cameras), you’ll need to hire a professional. This leaves you in a position to where you’re not only paying more for the cameras but paying more for the labor as well.

Final Thoughts

Choosing between a single vs dual dash cam is simple when you think about your needs. Most people find that using a single front-facing camera is ideal. However, it’s surely not going to give you the level of coverage that you need.

The final recommendation is to find two high-resolution cameras and network them together. This way, you have complete protection for your entire vehicle at an impressive quality.

Although it might cost substantially more than a single camera, it’s far less expensive than paying for damages that you weren’t responsible for. Just remember, if you’ve never installed a dash cam before, you might want to ask a professional for help.
