3. Configurare și instalare
Proper installation is crucial for the hard-wire kit's functionality. If you are unfamiliar with vehicle electrical systems, it is recommended to seek professional assistance.
Diagrama de cablare:
The hard-wire kit consists of three main wires:
- Fir negru (GND): Connect to a metal bolt or screw on the vehicle chassis for ground.
- Fir roșu (ACC): Connect to a fuse in the fuse box that is only powered when the ignition is on (Accessory power).
- Yellow Wire (BAT+): Connect to a fuse in the fuse box that has constant power, even when the ignition is off (Battery power).

Figure 4: Hard-wire kit control box showing input and output cables, and connections for GND, ACC, and BAT+.
Pașii de instalare:
- Localizați cutia de siguranțe: Refer to your vehicle's owner's manual to find the location of the fuse box. Common locations include under the dashboard, in the glove compartment, or under the hood.
- Identificați sloturile siguranțelor: Using a circuit tester, identify a fuse slot that provides ACC power (on with ignition) for the Red wire and a fuse slot that provides constant BAT+ power (always on) for the Yellow wire.
- Select Correct Fuse Type: Choose the appropriate fuse tap from the kit that matches the fuse type in your vehicle's fuse box.
- Connect Wires to Fuse Taps: Insert the Red and Yellow wires into their respective fuse taps. Insert the original fuse into the lower slot of the fuse tap and a new fuse (matching the original's amperage) into the upper slot for the hard-wire kit.
- Introduceți prizele de siguranță: Plug the fuse taps into the identified ACC and BAT+ fuse slots.
- Locate a Ground Point: Connect the Black (GND) wire to a secure metal bolt or screw on the vehicle's chassis that is free of paint or rust.
- Traseul cablurilor: Carefully route the Micro-USB output cable to your dash camera, ensuring it does not interfere with driving controls or airbags. Conceal the cable behind trim panels for a clean installation.
- Conectați-vă la Dash Cam: Plug the Micro-USB connector into your dash camera.
- Sistem de testare: Start your vehicle to ensure the dash cam powers on. Turn off the vehicle and remove the key to verify the parking monitor mode activates (if enabled on your dash cam).

4. Instrucțiuni de utilizare
Parking Monitor Mode:
Once correctly installed, the hard-wire kit enables your dash camera's parking monitor function. When your vehicle is turned off, the kit continues to supply power from the vehicle battery, allowing the dash cam to record in parking mode (e.g., time-lapse or motion detection, depending on your dash cam's features).
Vol. Scăzuttage Protecție:
The hard-wire kit features an integrated low voltage protection system to prevent excessive drain on your vehicle's battery. If the vehicle battery voltage drops below a preset threshold, the kit will automatically cut power to the dash camera.
- For 12V batteries, power is cut at 11.6V, 12.0V, 12.2V, or 12.4V (user adjustable).
- For 24V batteries, power is cut at 23.6V, 24.0V, 24.4V, or 24.8V (user adjustable).
To adjust the protection voltage, press and hold the '+' or '-' buttons on the hard-wire kit box for 3 seconds to display the current setting, then use the buttons to select the desired voltage. The digital display on the hard-wire kit box will show the current voltagsetarea.

5. Întreținere
- Verificări regulate: Periodically inspect the wiring for any signs of wear, damage, or loose connections.
- Fuse Integrity: Ensure the fuses in the fuse taps are correctly seated and not blown. Replace blown fuses with ones of the same ampepoca.
- Curăţenie: Keep the hard-wire kit box and connections free from dust and moisture.
- Conditii de mediu: Avoid exposing the kit to extreme temperatures or direct sunlight for prolonged periods, which could affect its lifespan.

| Problemă | Cauza posibila | Soluţie |
|---|---|---|
| Camera de bord nu pornește. | Loose connection, blown fuse, incorrect wiring, vehicle battery too low. | Check all connections. Inspect fuses in fuse taps and replace if blown. Verify wiring (GND, ACC, BAT+). Check vehicle battery voltage. |
| Parking monitor mode not activating. | Dash cam setting not enabled, incorrect BAT+ connection, low voltagProtecția e activată. | Ensure parking mode is enabled in your dash cam's settings. Verify the Yellow (BAT+) wire is connected to a constant power source. Check if low voltage protection has cut power. |
| Bateria vehiculului se descarcă repede. | Vol. Scăzuttage protection set too low, dash cam consuming too much power in parking mode. | Adjust the low voltage protection setting to a higher value. Consider using a dash cam with more efficient parking mode options (e.g., motion detection only). |
| Voltage display on kit box is off. | Problemă de alimentare, defecțiune internă. | Ensure the kit is receiving power. If the issue persists, contact customer support. |
| Micro-USB connector does not fit. | Incompatible dash cam port (e.g., USB-C, Mini-USB). | This kit is designed for Micro-USB ports only. Verify your dash cam's port type. |
