How to Connect a Dash Cam to Your Car Video Screen

What connecting to a car screen means

A dash cam and a car display are separate devices. To view the camera feed on a screen that is not built into the dash cam, the camera needs a video output and the screen needs a video input. The common ways to see video are the unit's own dash cam screen, a phone through dash cam Wi-Fi apps, or a wired output to a separate display.

This article focuses on the wired path: AV output, HDMI, and RCA. If your car has a large factory infotainment screen, a wired connection often requires an aftermarket monitor. Many factory screens do not expose a video input. If that sounds complicated, a mirror dash cam gives you a built-in display without a separate screen.

AV output and RCA connections

AV output means the dash cam sends an analog composite video signal to another screen. This connection often uses a small audio/video jack on the camera and RCA connectors on the monitor. The yellow RCA connector carries video, and the white or red connectors carry audio if the model supports it.

To connect, plug the dash cam into a monitor with a matching video input. This is the same type of connection used by many aftermarket backup cameras, so it can be useful for a front and rear dash cam when you want a larger rear view.

HDMI connections

Some dash cams have an HDMI port for video output. HDMI carries a digital signal, which can preserve a clean picture. If both the dash cam and the display support HDMI, the setup can be a simple cable connection.

The catch is that HDMI inputs are uncommon on car screens. A dash cam with HDMI output still needs a display that accepts HDMI, and the camera may require a menu setting to turn the output on. For most drivers, HDMI is more practical for playing back footage on a television through dash cam video playback than for daily use in the car.

What to check before you buy

Before buying a dash cam for a car screen connection, check the connectors. Look for terms such as AV out, video out, RCA out, or HDMI out on the specification page. Then check the display for a matching input and confirm that the cable can reach.

Think about placement and power. A separate monitor needs power, and the cable route should not block the driver's view or interfere with the controls. If you want backup-camera behavior, look for a reverse trigger wire on the monitor or the dash cam.

• Video output type: AV, RCA, or HDMI
• Cable length and routing
• Power source for the monitor
• Reverse trigger support for automatic rear view
• Whether the display accepts the video format from the dash cam

Keep your eyes on the road

An extra screen can help, but it can also become a distraction. IIHS notes that manipulating a cellphone while driving increases crash risk, and the CDC covers distracted driving as one of its transportation safety topics. Some vehicles have crash avoidance technologies that can warn the driver, but those systems do not replace attention. Connect and adjust the setup while parked, place the screen where you can glance at it without turning your head, and keep your attention on the road.

If your goal is to use the dash cam as a backup camera, wire the reverse trigger and test it in a parking lot. For detailed steps, see how to use dash cam as backup camera.

Alternatives when your car has no video input

If your car's screen has no video input, the easiest way to view footage is on the dash cam itself or through a phone app. Many dash cams create a local Wi-Fi network, and Wi-Fi dash cams let you view the feed without extra cables.

A rearview mirror dash cam is another alternative. It uses the space where the factory mirror sits and shows front and rear camera views on a built-in display. That is why mirror dash cam models appeal to drivers who want a larger image without modifying the dashboard.

What to pick for your setup

For a simple wired connection to an external monitor, choose a dash cam with a clear video output and a cable that matches your display. A high-definition dash cam is enough for most small car screens. If your display can show more detail and you want the sharpest files later, consider a higher-resolution dash cam.

If you want a built-in screen with no separate monitor, a mirror dash cam avoids the video input problem entirely. If you mostly review clips on your phone, a Wi-Fi model is usually simpler. Match the connection type to the screen you already have, and confirm that the cable can be routed safely before you install.

Questions

Can any dash cam connect to my car's existing screen?

No. The dash cam must have a video output and the car screen must have a matching input. Many factory infotainment screens have no AV or HDMI input, so check both sides before buying.

What is the difference between AV output and HDMI output?

AV output sends analog video over a small AV jack or RCA connectors. HDMI sends digital video over an HDMI cable. Both can show the live feed, but the dash cam and display must support the same type.

Do I need a special cable for RCA connections?

Dash cams with AV output usually include a cable that ends in RCA connectors or fits the camera's AV jack. If your monitor uses a different input, you may need an adapter.

Will connecting to a car screen stop the dash cam from recording?

In most cases, video output runs alongside normal recording. Some models let you choose between the built-in screen and external output, so check the menu. Recording continues unless you pause it manually.

Is it safe to watch the dash cam feed while driving?

Keep your attention on the road. IIHS research links manipulating devices while driving to higher crash risk, so set up the view when parked and glance at the screen only when necessary.

What if I mainly want a backup camera view?

If the dash cam has a video output and the monitor supports a reverse trigger, the image can appear automatically when you shift into reverse. See how to use dash cam as backup camera for the setup steps.
