5. Operating Instructions
5.1. Powering On/Off
- The dash camera will automatically power on and begin recording when your vehicle's ignition is turned on (if connected to the car charger).
- It will automatically power off when the ignition is turned off.
5.2. Basic Recording
Once powered on, the dash camera will automatically start loop recording. Video segments are saved to the Micro SD card. When the card is full, the oldest unlocked files will be overwritten.
5.3. Wi-Fi Connection and App Usage
The dash camera features built-in 2.4G Wi-Fi for seamless connection to your smartphone via the Viidure app.
- Download the Viidure App from your smartphone's app store or by scanning the QR code below.

5.5. G-Sensor (Gravity Sensor)
The built-in G-Sensor detects sudden movements or collisions. In the event of an impact, the current video segment will be automatically locked and saved to prevent it from being overwritten by loop recording. This ensures critical footage is protected.
