How to Install a Dual Dash Cam: Mounting, Wiring & Storage

A dual dash cam can only record useful footage when both views are positioned correctly, the power supply is reliable and the storage settings are right. Before installation, read the camera's manual and confirm which configuration you bought: some second cameras face the rear road, while others are intended for the cabin. This guide covers the checks that apply to most dual-camera systems.

1. Confirm the exact camera configuration

Check whether the package includes a front camera, rear camera or cabin-facing camera, which cables are supplied, and whether a memory card is included. Variants can differ. Do not assume a dual-lens product includes every cable or accessory shown in a marketing image; use the selected option's package list.

The AZDOME GS63H dash cam listing offers single- and dual-lens choices, as well as different memory-card options. Select the lens/card configuration you actually need and review the included items before ordering.

2. Choose a suitable front-camera position

Position the camera where it has a clear view of the road and does not obstruct the driver's view. A location near the rear-view mirror is often considered, but the exact position depends on the windshield, mirror, tint, sensor housings and the camera's mounting instructions. Make sure the lens can see the road properly through the area swept by the wipers.

Check the view from the driver's seat before permanently attaching the mount. Avoid areas where dashboard reflections, stickers, tint bands or the vehicle's sensor housing block the lens. Clean and dry the mounting surface and follow the adhesive or bracket instructions supplied by the manufacturer.

3. Position the second camera for its intended view

For a rear-facing camera, choose a position that gives a clear view through the rear glass and does not interfere with defrosting lines or the rear wiper. If the second camera is cabin-facing, aim it according to the device's intended use. Route the cable with enough slack for safe movement but not so much that it hangs into the cabin.

Check the image on the dash cam or companion app after mounting. A small change in angle can make a meaningful difference to framing.

4. Route power cables safely

Use the power cable and method recommended for the camera. A plug-in accessory socket and a hardwire installation are not the same. Hardwiring may require an appropriate kit, correct fuse connection and vehicle-specific knowledge; parking recording may be available only when the camera and power setup support it.

Keep cables away from pedals, steering parts, gear selectors and airbags. Some vehicles have side-curtain airbags behind the A-pillar trim, so do not route a cable across an airbag deployment path. If you are not sure how to route the cable safely or connect a fuse, use a qualified installer rather than removing trim by guesswork.

5. Choose the correct memory card

Use the capacity and card type recommended by the camera manufacturer. Continuous video recording places sustained demands on storage, so a card intended for repeated recording is often a better fit than a card chosen only by its advertised capacity. Check whether a card is included with your selected package and whether the camera supports the capacity you plan to use.

For a new card, format it using the camera's own menu when the manual recommends that process. Follow the manufacturer's replacement guidance if recording errors, missing files or repeated card warnings occur.

6. Configure the main settings

• Date and time: Set the correct time zone and clock; inaccurate timestamps make footage harder to interpret.
• Resolution and frame rate: Select a supported setting that balances detail, storage use and the camera's available options.
• GPS: If your model supports GPS, confirm that it is enabled and that the device obtains a signal as described in the manual.
• Loop recording: Understand how older clips are overwritten and how event clips are protected.
• G-sensor sensitivity: Set event sensitivity according to the manual and real driving conditions; an overly sensitive setting may lock too many files.
• Wi-Fi/app connection: If supported, pair the phone as instructed and test playback or file transfer before relying on the setup.

7. Test both views before every day-to-day use

Record a short clip and review it. Check that the front view is level, the second view points in the intended direction, both recordings are saved and the sound or time settings behave as expected. Test in daylight and again in low light; reflections and glare may be more noticeable at night.

Do not assume parking mode works just because the camera records while driving. If your particular camera supports parking recording, verify the required power method, battery-protection instructions and the behaviour of the selected mode in the product manual.

Common installation mistakes

• Placing the camera where it blocks the driver's view or sits outside the useful wiper area.
• Routing wires near pedals or across an airbag deployment path.
• Assuming a memory card, hardwire kit or rear-camera cable is included in every variant.
• Never testing the second view or confirming recordings after the first setup.
• Expecting parking recording without confirming camera support and compatible power.

Before you buy

Compare single- vs dual-camera coverage, GPS and Wi-Fi support, night recording, memory-card options, included cables and the power method. The AZDOME GS63H 4K dash cam is one option to review, but confirm the exact features of the configuration selected on the product page.
