2. Características do produto

• Aplicación ampla: Compatible with most Mini USB powered devices such as dashcams, GPS navigators, and radar detectors.
• Altos estándares de seguridade: Converts 12V-24V vehicle voltage to 5V, supporting extended parking surveillance. Integrated protection prevents overcurrent and overheating.
• Baixo Voltage Protección: Automatically detects battery voltage corta a corrente se o volumetage drops below 11.6V (for 12V systems) or 23.6V (for 24V systems) to ensure the vehicle can start.
• ACC Voltage Reduction Line: Features a three-wire connection (BAT+, GND-, ACC) for intelligent power management. The dashcam automatically switches to parking mode when the engine is off and to normal recording when the engine is on.
• Vixilancia as 24 horas: Provides continuous power to the dashcam from the fuse box, enabling 24-hour parking monitoring.

4. Configuración e instalación

Proper installation is essential for the correct functioning of the hardwired kit and your dashcam. If you are unfamiliar with vehicle electrical systems, it is recommended to seek professional installation.

4.1 Identifying Wires

• Yellow Wire (BAT+): Connects to a constant fuse in your vehicle's fuse box. This provides continuous power even when the ignition is off.
• Black Wire (GND-): Connects to a metal bolt or screw on the vehicle's chassis for grounding. Ensure a secure connection to bare metal.
• Cable vermello (ACC): Connects to an ACC (Accessory) fuse in your vehicle's fuse box. This fuse is only powered when the ignition is on.

4.2 Pasos da instalación

1. Montar a cámara do salpicadero: Fix your dashcam in the desired position on the windshield, ensuring it does not obstruct your view.
2. Ruta do cable: Carefully route the Mini USB power cable from the dashcam along the windshield trim, down the A-pillar, and towards the vehicle's fuse box. Ensure the cable is tucked away neatly and securely.
3. Conecte o cable de terra: Attach the black wire (GND-) to a suitable metal grounding point on the vehicle's chassis, typically a bolt or screw.
4. Connect Constant Power (BAT+): Using the provided fuse tap, connect the yellow wire (BAT+) to a constant power fuse in your vehicle's fuse box. This fuse should provide power even when the ignition is off.
5. Connect Accessory Power (ACC): Using another fuse tap, connect the red wire (ACC) to an accessory power fuse in your vehicle's fuse box. This fuse should only provide power when the ignition is on.
6. Connect to Dashcam: Plug the Mini USB connector into your dashcam's power input.
7. Funcionalidade de proba: Start your vehicle to ensure the dashcam powers on and begins recording. Turn off the vehicle to verify that the dashcam switches to parking mode (if supported) or powers off correctly based on your dashcam's settings.

Note: If you are unfamiliar with vehicle electrical systems, please consult a professional installer for assistance.

5. Instrucións de funcionamento

Once installed, the MEIRIYFA Hardwired Kit operates automatically to manage power to your dashcam.

• Funcionamento normal: When the vehicle's engine is running, the red ACC wire detects ignition power, and the kit provides continuous 5V power to the dashcam for normal recording.
• Parking Surveillance: When the vehicle's engine is turned off, the ACC power is cut. The kit continues to draw power from the constant BAT+ line, allowing the dashcam to enter its parking surveillance mode (if supported by your dashcam). This enables 24-hour monitoring.
• Baixo Voltage Protección: The built-in low voltage protection circuit monitors your vehicle's battery voltage. Se a batería voltage drops below 11.6V (for 12V systems) or 23.6V (for 24V systems), the kit will automatically cut off power to the dashcam to prevent excessive battery drain and ensure the vehicle can start.

6. Mantemento

The MEIRIYFA Hardwired Kit is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure optimal performance:

• Comproba as conexións: Periodically inspect all wire connections (ground, BAT+, ACC) to ensure they remain secure and free from corrosion.
• Fuse Integrity: The kit includes fuse taps. Ensure the fuses are correctly seated and not blown. If a fuse blows, replace it with one of the same ampclasificación erage.
• Enrutamento de cables: Verify that the cables are still securely routed and not pinched or exposed to excessive wear.
• Limpeza: Keep the step-down converter box free from excessive dust or debris.
