- Connecter l'alimentation : Plug the mini USB car charger into your vehicle's 12V power outlet (cigarette lighter socket). Connect the other end of the charger cable to the 'TYPE-C' USB-C port on the GPS module. Use the provided crowbar tool and cable clips to neatly tuck away the cables along the vehicle's trim.

5.3 Commande vocale
For hands-free operation, the dash cam supports voice commands. Ensure the voice control feature is enabled in the settings. Common commands include:

6. Fonctionnalités avancées
6.1 Modes d'enregistrement vidéo
- Enregistrement en boucle : La caméra embarquée enregistre en continu des vidéos par courtes séquences (par exemple, 1, 3 ou 5 minutes). Lorsque la carte mémoire est pleine, la plus ancienne séquence déverrouillée est supprimée. fileLes enregistrements sont automatiquement écrasés pour faire de la place aux nouveaux enregistrements.
- Enregistrement d'urgence (capteur G) : The built-in G-sensor detects sudden impacts or collisions. When triggered, it automatically locks the current video segment, protecting it from being overwritten by loop recording.
- Surveillance du stationnement: Provides 24-hour surveillance for your parked vehicle. This mode requires an optional hardwire kit (ASIN B0BG5DM5CL) for continuous power. It offers two sub-modes:
- Collision-Detection Mode: Records a short video clip if an impact is detected while parked.
- Mode accéléré : Enregistre des vidéos en continu à faible fréquence d'images, compressant des heures de nourrituretage en quelques minutes pour un stockage et un ré- stockage efficacesview.

Vision nocturne améliorée 6.2
Equipped with STARVIS 2 HDR technology and a large aperture lens, the D4 Duo delivers superior low-light clarity, capturing clear footage even in challenging nighttime conditions. This technology significantly reduces image noise and enhances detail compared to standard dash cams.
