Let’s get started.

Installation Steps

Step1: Preparing for Installation

Installing a dash cam is a straightforward process, but it requires some basic preparation to ensure everything goes smoothly. Before you begin, please prepare the following accessories:

Check Your Dash Cam Kit:

  • Front Camera: Captures the view in front of your vehicle, typically mounted on the front windshield.
  • Rear Camera (if included): Records what’s behind your vehicle; some kits may include this.
  • Power Cables: Provide power to the cameras.
  • Mounting Accessories: Including mounts, suction cups, or adhesive tapes for securing the cameras.

Clean the Windshield:

  • Gently clean the area of the windshield where the camera will be installed using a damp cloth.
  • Wipe down with a clean towel or cloth to ensure the area is completely dry, allowing the mounting accessories to adhere firmly.

For the SD card, if your kit does not include one, you may need to purchase it separately.

An SD card is an essential storage medium for recording video, and choosing the right one is crucial for ensuring the quality and longevity of your recordings.

We have a concise guide that can help you select the right SD card; click here to read the SD Card Buying Guide.

Once you have all the items ready and the installation area is clean, you can move on to the actual installation steps.

We will use the DDPAI N5 Dual as an example to guide you through the installation but keep in mind that these steps are generally applicable.

Step2: Installation of front camera

Now that your windshield is clean and clear, you’re ready to install the front camera. Follow these steps to ensure the camera is correctly placed and securely attached:

Use the power cable that came with your dash cam to establish a connection to your vehicle’s power supply.

This cable is usually equipped with a plug that fits into your car’s cigarette lighter socket, ensuring a stable power source for the dash cam while driving.

Identify the ideal spot on the windshield, typically recommended to be near the center top behind the rearview mirror to avoid obstructing the driver’s view and to capture a wide angle of the road ahead.

After positioning the dash cam, connect the cables to the appropriate ports on the camera. Make sure each plug is securely inserted to ensure stable operation.

This ensures that your dash cam has a reliable power source and is ready to record your drives.

After completing the installation, make sure the power cable a neatly routed to avoid interference with the line of sight or operation while driving.

It is advisable to conceal the wires along the edges of the car’s interior trim to maintain a clean look within the cabin and minimize the risk of exposed wiring.

Note: The cigarette lighter receptacle might be positioned differently in your car. The picture is provided for reference only.

Below is the video guide for routing the cables for the front camera:

Now, your front camera should be securely mounted on the windshield and connected to the power supply.

Before moving on to the next step, try powering on the dash cam to check the recording angle and video quality of the camera.

Step 3: Installation of rear camera

The rear camera provides a view of the area behind your vehicle, which helps record situations that occur while driving.

Here are the steps for installing the rear camera:

Typically, the power cable for the rear camera is longer than the front camera’s cable, facilitating its stretch from the front of the vehicle to the rear.

As shown in the following image, you will see a longer cable used to connect the rear camera.

Remove the rear camera, peel off the protective film from the adhesive tape, and then secure it to the cleaned area.

Press down for a few seconds to ensure the tape adheres firmly to the surface.

Once the rear camera is in place, connect it to the front camera or directly to the dash cam main unit using the long power cable, following the specific guide for your product.

You can then arrange the cables, making sure they are hidden along the interior of the car, not affecting the comfort of the passengers or the aesthetic of the vehicle’s interior.

Now, your rear camera should be installed and connected.

Before moving on to the next step, test to ensure the rear camera is functioning properly and adjust it to provide the best possible view.

Step 4: Testing the Dash Cam

The final step is to test the dash cam to ensure everything is functioning properly. Here are the general steps for testing your dash cam:

  1. Power On the Dash Cam: Start your vehicle, and the dash cam will typically start automatically. If it doesn’t, manually turn on the device.
  2. Connect to a Smartphone: Ensure your smartphone’s WiFi is on and connect to the dash cam’s WiFi signal. Go to your phone’s WiFi settings, select the network emitted by the dash cam, and connect.
  3. Launch the Control App: Open the dedicated dash cam app, such as the DDPAI app. The first time you use it, you may need to follow the on-screen instructions for pairing and setting up.
  4. Check Functions: View the live video stream in the app to check the angles and video clarity of both the front and rear cameras. Make sure you can control the camera’s recording and photo-taking functions through the app.
  5. Adjust Settings: Within the app, tweak the dash cam’s settings, such as resolution, parking mode, and other features.
  6. Record and Playback: Try controlling the dash cam through the app to record a short video, then playback to confirm the video and audio quality.
  7. Check Storage: Ensure that the video files have been correctly saved to the SD card or internal storage.
  8. Learn the Emergency Recording Feature: Familiarize yourself with how to start an emergency recording in the app, which can instantly save the current recording during an unexpected event.


  • In-home Testing your dash cam: Before mounting it in your car, test the dash cam by connecting it to your computer or a power strip with a Type-C cable to ensure the device is working properly.
  • SD Card Formatting: Format new microSD cards in your dash cam before use to ensure compatibility and efficient space utilization.
  • Emergency SD Card Handling: In the event of an accident or a significant event, promptly remove the SD card from the dash cam to prevent the footage from being overwritten. Alternatively, connect to the dash cam as soon as possible to download the video directly to your smartphone or another device. This ensures that important recordings are secured and preserved immediately.
  • Proper Handling: When disconnecting or connecting the power cable to your dash cam, always grip the plug firmly to avoid damaging the cable or port.

By following the installation steps outlined in this guide, you’re set to capture everything from the ordinary to the extraordinary.
