Operating Instructions
Automatic Recording
The dash cam automatically starts recording when connected to power (e.g., when you start your car) and stops when power is disconnected. A red light flashing on the screen indicates active recording.
Loop Recording
The device supports seamless loop recording, overwriting the oldest footage when the memory card is full. Video segments are typically recorded in 1, 2, or 3-minute intervals. This ensures continuous recording without manual intervention.

G-Sensor (Accident Lock)
The built-in G-sensor detects sudden shocks or collisions. When activated, it automatically locks the current video footage to prevent it from being overwritten during loop recording. This protects critical evidence in case of an accident.

Parking Monitoring (Requires Hardwire Kit)
For 24-hour surveillance, the parking monitor function will activate and record if a collision or impact is detected while your vehicle is parked. This feature requires a separate hardwire kit for continuous power supply.

Voice Prompts
The dash cam provides intelligent voice prompts to notify you of its current status, such as "Recording Stopped," "Formatted," "Start Recording," or "Successfully take a photo." This helps you stay informed without diverting your attention from driving.
