Setup
1. Insert Micro SD Card

2. Mount the Front Dashcam
Clean the area on your windshield where you intend to mount the dashcam. Attach the mounting bracket to the dashcam. Remove the protective film from the adhesive pad on the bracket and firmly press the dashcam onto the chosen location on your front windshield, ideally near the rearview mirror for an unobstructed view. Ensure the camera lens has a clear view of the road ahead.

3. Install the Rear Camera
Connect the rear camera to the main dashcam unit using the provided cable. Route the cable neatly along the vehicle's headliner and pillars to the rear of the vehicle. Mount the rear camera on the rear windshield, ensuring it has a clear view of the road behind. Secure the cable to prevent interference with driving.
4. Power Connection
Connect the dashcam to your vehicle's power outlet (e.g., cigarette lighter socket) using the provided power cable. Route the cable discreetly to avoid obstructing your view or interfering with vehicle controls. The dashcam will typically power on automatically when the vehicle starts and power off when the engine is turned off.
Operating Instructions
1. Automatic Recording
Once powered on, the dashcam will automatically begin recording video from both the front (4K) and rear (1080P) cameras. Recording is continuous, utilizing loop recording to overwrite the oldest files when the memory card is full.

2. Wi-Fi and App Control
Download the companion app (e.g., "FinalCamX" as shown in product images) from your smartphone's app store (App Store for iOS, Google Play for Android). Enable Wi-Fi on your dashcam and connect your smartphone to the dashcam's Wi-Fi network. Through the app, you can:
- View live footage from both cameras.
- Review recorded videos and photos.
- Download footage directly to your phone.
- Adjust dashcam settings.
- Share videos to social media platforms.

3. GPS Tracking
The integrated GPS module automatically records your vehicle's speed, driving route, and location data. This information is embedded with your video footage and can be viewed via the companion app or dedicated PC software (if available) to provide comprehensive evidence in case of an incident.
4. Parking Monitor
When your vehicle is parked and the dashcam is connected to a continuous power source (e.g., hardwired kit, sold separately), the 24-hour parking monitor activates. It uses motion detection to automatically start recording if an impact or movement is detected around your vehicle. The dashcam features an automatic low-voltage shutdown to prevent draining your car's battery.
5. Wide Angle View and Night Vision
The 120° wide-angle lenses on both front and rear cameras capture a broad view of the road, reducing blind spots. The enhanced night vision, supported by an F1.8 large aperture and 6-glass lens, ensures clear and detailed recordings even in low-light or nighttime conditions.

6. WDR (Wide Dynamic Range)
The dashcam utilizes WDR technology to balance exposure in scenes with high contrast, such as entering or exiting tunnels, or driving against bright sunlight. This ensures that both bright and dark areas of the image are clearly visible.

Maintenance
1. Cleaning the Device
Use a soft, dry cloth to clean the dashcam's lens and body. Do not use abrasive cleaners or solvents, as they may damage the device. Ensure the lens is free from dust and smudges for optimal recording quality.
2. Micro SD Card Management
- Formatting: It is recommended to format the Micro SD card regularly (e.g., once a month) to maintain optimal performance and prevent data corruption. This can usually be done through the dashcam's settings menu or the companion app. Formatting will erase all data on the card, so back up any important files first.
- Card Lifespan: Micro SD cards have a limited number of write cycles. If you experience recording errors, consider replacing the card with a new, high-quality endurance Micro SD card.
3. Firmware Updates
Check the manufacturer's website or the companion app periodically for firmware updates. Keeping your dashcam's firmware up-to-date can improve performance, add new features, and fix bugs.
Troubleshooting
- Dashcam does not power on:
- Ensure the power cable is securely connected to both the dashcam and the vehicle's power outlet.
- Check if the vehicle's power outlet is functioning (e.g., by plugging in another device).
- Verify the vehicle's fuse for the power outlet is not blown.
- Recording stops or footage is corrupted:
- Format the Micro SD card.
- Ensure you are using a high-quality, high-endurance Micro SD card (Class 10 or U3 recommended).
- The card may be full; loop recording should prevent this, but check if emergency recordings are filling the card.
- The Micro SD card may have reached its lifespan; try replacing it.
- Wi-Fi connection issues:
- Ensure Wi-Fi is enabled on the dashcam and your smartphone.
- Restart both the dashcam and your smartphone.
- Make sure you are within close proximity to the dashcam.
- Reinstall the companion app.
- Poor video quality:
- Clean the camera lenses.
- Ensure the protective film has been removed from the lenses.
- Check dashcam settings for resolution and exposure.
- Verify the mounting position is stable and not vibrating.
- Parking monitor not working:
- Ensure the dashcam is connected to a continuous power supply (e.g., hardwired kit) that provides power when the vehicle is off.
- Check parking monitor settings in the dashcam menu or app.
