4. Setup
Follow these steps for proper installation of your Avylet Dash Cam A4:
- Clean the Windshield: Before installing, thoroughly clean the area on your windshield where the dash cam will be mounted. Ensure it is free of dust and grease for optimal adhesion.
- Apply Electrostatic Film: Apply the provided electrostatic film to the front windshield. This helps protect your windshield and allows for easier removal of the dash cam later.
- Prepare the Dash Cam: Remove the red protective film from the adhesive bracket on the main dash cam unit.
- Install Front Camera: Carefully install the front camera onto the prepared area of the windshield. The front camera offers a 270° rotation angle for flexible adjustment.
- Install Rear Camera: Install the rear camera on the rear windshield. The rear camera features a 360° rotatable lens for comprehensive coverage. Ensure the cable is routed neatly.
- Route Cables: Use the trim removal tool and cable clips to route the power cable and rear camera cable along the edges of your car's interior, hiding any excess cables in the gaps. This ensures a clean and unobtrusive installation.
- Connect Power: Connect the car charger to your vehicle's cigarette lighter outlet. Then, connect the power cable from the charger to the main dash cam unit. This links both the front and rear cameras for power.
- Adjust Angle: Once powered on, adjust the dash cam's angle to ensure it captures the desired view of the road. Use the 1.5-inch IPS screen for real-time monitoring to achieve the perfect angle.

5. Operating the Dash Cam
5.1. Power On/Off
The dash cam automatically powers on when connected to the car charger and the vehicle's ignition is turned on. It powers off automatically when the ignition is turned off.
5.2. Wi-Fi & App Control
The Avylet Dash Cam A4 features built-in Wi-Fi for seamless control via the "AUTOSOCT" mobile app (available for Android and iOS). This allows you to:
- Stream live video from the dash cam.
- Download recorded videos directly to your phone.
- Adjust camera settings (e.g., resolution, G-sensor sensitivity).
- Perform OTA (Over-The-Air) firmware updates.
- Edit and share your footage.

5.3. Loop Recording & G-Sensor
The dash cam continuously records video in segments (1, 3, or 5 minutes). When the memory card is full, the oldest unlocked video files are automatically overwritten to ensure uninterrupted recording. The built-in G-sensor detects sudden movements or collisions. In such events, it automatically locks the current video footage to prevent it from being overwritten, preserving critical evidence.

5.4. Parking Monitoring
The dash cam offers 24-hour parking monitoring features:
- Parking Mode: In the event of a collision or emergency braking while parked, the dash cam automatically saves the recorded video clip.
- Time-Lapse: When the vehicle is parked, the dash cam continues to record at a reduced frame rate, saving storage space while providing continuous surveillance.
Note: An ACC hardwire kit is required for 24-hour parking monitoring (not included). Using other brands may cause compatibility issues.

5.5. External GPS Module (Optional)
The dash cam supports an optional external GPS module (not included). When connected, it records your location (longitude and latitude), route, speed, and time directly into the video files. This data can be accessed on both personal computers and mobile phones, providing crucial evidence for insurance claims or accident investigations.
To obtain the GPS module or download the necessary player, please reach out to Avylet customer support.

6. Maintenance
To ensure the longevity and optimal performance of your Avylet Dash Cam A4, follow these maintenance guidelines:
- Regular Cleaning: Periodically clean the camera lenses and the screen with a soft, lint-free cloth. Avoid using abrasive cleaners that could scratch the surfaces.
- Memory Card Management: Regularly format your memory card (at least once a month) to prevent data corruption and ensure smooth recording. Back up any important footage before formatting.
- Firmware Updates: Check for and install any available firmware updates via the "AUTOSOCT" app. Updates often include bug fixes, performance improvements, and new features.
- Temperature Considerations: While the super capacitor allows for operation in extreme temperatures (-4°F to 158°F), prolonged exposure to direct sunlight or extreme heat when parked can still affect the device's lifespan. If possible, park in shaded areas.
- Cable Management: Ensure all cables are securely tucked away and not interfering with vehicle operation or visibility. Regularly check for any signs of wear or damage to the cables.
