4. Setup

Proper setup is crucial for the optimal performance of your dash cam. Follow these steps carefully:

4.1. Install Memory Card

1. Insert a new TF card (microSD card) into the card slot.
2. Power on the recorder.
3. Access the Menu Interface.
4. Select the 'Format Card' option and confirm.
5. Wait for the formatting process to complete. The dash cam will automatically start recording once formatted.

4.2. Install Cam onto Car Windshield

The host (main unit) is best installed on the car glass behind the rearview mirror. The rear camera should be installed in the middle of the rear windshield.

1. Choose the desired location on your windshield.
2. Clean the area thoroughly with a screen cleaning paper.
3. Peel off the protective film from the electrostatic sticker and stick it on the car windshield.
4. Attach the dash cam to the electrostatic sticker using the adhesive.

4.3. Install Power Cord (Hardwire Kit)

The dash cam requires a hardwire connection for continuous power and parking monitoring. Two connection methods are provided:

• OBD Connecting Cable: Plug the OBD connector into your car's OBD socket, typically located under the dashboard near the steering wheel.
• Fuse Box Connection: Connect the fuse connecting cable to an appropriate fuse in your car's fuse box. Refer to your vehicle's manual for fuse box diagrams.

Always ensure the dash cam is connected to power when in use.

5. Operating Instructions

This section details the various operating modes and functions of your TIESFONG A7WB dash cam.

5.1. Recording Modes

The dash camera supports multiple recording configurations:

• 3-Channel Mode: Records simultaneously from front (1440P), interior (1080P), and rear (1080P) cameras.
• 2-Channel Mode: Records from front (4K) and either interior or rear camera (1080P).
• 1-Channel Mode: Records from the front camera only (4K).

Note: Due to the small screen size, it is recommended to view and download HD footage via the mobile app for optimal clarity.

5.2. Night Vision

The dash cam is designed for superior low-light performance:

• The interior camera is equipped with 4 infrared LED lights to capture clear images of the driver and passengers in dark conditions.
• Front and rear cameras utilize WDR (Wide Dynamic Range) and HDR (High Dynamic Range) technology to automatically balance light and dark areas, ensuring clear video even in challenging lighting.

5.3. G-Sensor (Emergency Lockout)

The built-in G-sensor detects sudden impacts or collisions. When triggered, it automatically locks the current video segment, preventing it from being overwritten by loop recording. This ensures critical evidence is preserved in case of an accident.

5.4. 24-Hour Radar Parking Monitor & Low Voltage Protection

When your vehicle is parked and the engine is off, the intelligent radar monitoring system activates. If a moving object approaches within 1-3 meters of your car, the dash cam will automatically start recording. This feature helps protect your vehicle from potential incidents while unattended.

The system also includes low voltage protection with three adjustable settings (11.8V/12.0V/12.2V). If your car battery voltage drops below the set threshold, the dash cam will automatically power off to prevent draining your vehicle's battery.

5.5. Loop Recording

The dash cam supports seamless loop recording. When the 128GB SD card (included) reaches its full capacity, the oldest unlocked video files will be automatically overwritten by new recordings. This ensures continuous recording without the need for manual card replacement. Emergency locked videos are protected from overwriting.

5.6. CPL Filter Usage

The included CPL (Circular Polarizing Lens) filter for the front camera helps reduce glare and reflections from the car windshield, improving video clarity and contrast, especially in bright conditions or when facing reflective surfaces.

5.7. Built-in Wi-Fi & App Connectivity

The dash cam features built-in Wi-Fi for easy connection to your smartphone via the “TSCAM” app. Through the app, you can:

• View live footage from the cameras.
• Playback recorded videos.
• Download video files to your phone.
• Edit and share your recordings.

Note: The app does not support remote live viewing when you are away from the vehicle. You must be within Wi-Fi range of the dash cam.

5.8. Built-in GPS Tracking

The integrated GPS module records your driving route, speed, and precise location in real-time. This data is embedded in the video files and can be viewed using the “TSCAM” app or a compatible GPS player software (like GXPlayer) on your computer. This provides valuable information for accident reconstruction or route analysis.

6. Maintenance

To ensure the longevity and reliable performance of your dash cam, consider the following maintenance tips:

• SD Card Formatting: Regularly format the microSD card (e.g., once a month) through the dash cam's menu. This helps maintain optimal recording performance and prevents data corruption.
• Cleaning: Gently clean the camera lenses with a soft, lint-free cloth. Avoid abrasive materials or harsh chemicals.
• Temperature Resistance: The dash cam is designed to operate in a wide temperature range (-20°C to 65°C / -4°F to 149°F). However, prolonged exposure to extreme temperatures outside this range may affect performance.

7. Troubleshooting

If you encounter issues with your TIESFONG A7WB dash cam, please refer to the following common troubleshooting tips:

• Camera Not Recording: Ensure the SD card is properly inserted and formatted. Check if loop recording is enabled. Verify power connection.
• Poor Video Quality: Clean the camera lenses. Ensure the CPL filter is correctly installed if used. Check recording resolution settings.
• Wi-Fi Connection Issues: Ensure the dash cam's Wi-Fi is enabled. Restart both the dash cam and your smartphone. Ensure you are within close proximity to the dash cam.
• Parking Monitor Not Activating: Verify the radar switch is set to ON (0, 1, or 2). Ensure the hardwire kit is correctly installed and providing continuous power.
• Dash Cam Shuts Off Unexpectedly: Check the low voltage protection settings. Ensure your car battery is not low. Verify stable power connection.
