4. Opsætning og installation
Proper installation is crucial for optimal performance. The system is designed for wired connection to ensure stable signal transmission.
4.1 Strømtilslutning
The system is powered directly by your vehicle's electrical system. Ensure your vehicle's FUSE BOX is rated at 20A eller højere for the power supply. The power cord includes three main wires for connection:
- Sort ledning: Tilslut til negativ (-) terminal of the battery or a reliable ground point on the vehicle chassis.
- Gul ledning: Tilslut til en constant positive (+) power source (e.g., directly to the battery positive terminal or a fuse that is always live). This ensures continuous power for DVR recording even when the ignition is off.
- Rød ledning (ACC): Tilslut til en ignition-controlled positive (+) power source (e.g., a fuse that is only live when the ignition is on). This allows the system to power on/off with your vehicle's ignition.
If you prefer constant power for the monitor (always on), connect both the Red (ACC) and Yellow wires to the constant positive (+) power source.
