• Interior Mounting: Attach the rear camera to the inside of your rear windshield using the provided adhesive.

3.4 Power Connection

Connect the Type-C car charger to the dash cam's power input port and plug the other end into your vehicle's cigarette lighter socket. The dash cam will automatically power on and begin recording when the vehicle's ignition is turned on.

4. Operating Instructions

4.1 Basic Operation

• Power On/Off: The dash cam powers on automatically with vehicle ignition. To manually power on/off, press and hold the power button.
• Recording: Once powered on, the dash cam automatically starts recording. A red dot indicator on the screen confirms recording is active.

4.2 Recording Modes and Features

4.2.1 Dual Channel Recording

The dash cam records simultaneously from both the front and rear cameras. The front camera captures 4K UHD video with a 170-degree wide angle, while the rear camera records 1080P FHD video with a 140-degree wide angle, covering multiple lanes and reducing blind spots.

4.2.2 Seamless Loop Recording

When the memory card reaches its storage limit, the loop recording function automatically overwrites the oldest unlocked video files to ensure continuous recording. Recording intervals can typically be set to 1, 2, or 3 minutes in the settings.

4.2.3 G-Sensor (Emergency Lock)

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

4.2.4 24/7 Parking Monitor

With the parking monitor feature enabled, the dash cam will automatically start recording if it detects motion or a collision while your vehicle is parked. For continuous 24/7 parking surveillance, a hardwire kit (not included) is required to provide constant power to the dash cam.

4.2.5 Super Night Vision with WDR

The dash cam is equipped with an F1.8 aperture lens and Wide Dynamic Range (WDR) technology, which optimizes video quality in low-light conditions. This ensures clearer recordings at night, making license plates and road signs more discernible by balancing exposure in both bright and dark areas.

4.2.6 Time-Lapse Recording

When time-lapse recording is selected (requires hardwire kit), the dash cam records at a low frame rate (e.g., 1/2/5fps). This mode is ideal for extended parking surveillance, preserving video quality while significantly saving memory card space.

4.2.7 Smart Voice Prompts

The dash cam provides smart voice prompts to inform you of its current status, such as "Start Recording," "Recording Stopped," "Formatted," or "Successfully take a photo." This ensures you are aware of the device's operation without needing to look at the screen.
