3. Product Features

• 24/7 Parking Monitoring: Provides continuous power to your dash cam for recording incidents while the engine is off, covering vandalism or impacts when parked.
• Smart Low-Voltage Protection: Automatically cuts off power when the car battery voltage drops below 11.8V±0.2V (12V vehicles) or 23.8V±0.2V (24V vehicles) to prevent battery drain and ensure sufficient power for engine ignition.
• Stable Type-C Power Output: Designed with a USB Type-C output (5V/3A) for consistent power delivery to compatible dash cams during parking mode and daily driving.
• Built-In Safety Protection: Integrated safeguards against over-voltage, short circuits, and overheating ensure stable performance and enhanced safety.
• Wide Vehicle Compatibility & Clean Installation: Supports DC 12V–24V vehicles (cars, SUVs, trucks) and allows for a hidden installation without exposed cables.

5. Setup and Installation Guide

Proper installation is crucial for the hardwire kit to function correctly. We recommend professional installation if you are unsure about your vehicle's electrical system.

5.1 Wiring Overview

Image: Diagram showing the three main wires of the hardwire kit: Red (ACC), Yellow (B+), and Black (Ground), along with the hardwire box and USB-C output.

• Red Wire (ACC): Connect to an ACC fuse, which is powered only when the engine is on.
• Yellow Wire (B+): Connect to a constant power fuse, which is always powered (whether the engine is on or off).
• Black Wire (Ground): Connect to a metal screw or bolt on the vehicle for grounding.

5.2 Installation Steps

1. Choose the Best Location: Select a spot for your dash cam with a clear, unobstructed view that does not block your driving view.
2. Locate the Vehicle Fuse Box: Your vehicle's fuse box is typically located under the dashboard or in the engine bay. Refer to your vehicle's manual for its exact location. Use the included trim tool to carefully open the fuse box cover.
3. Identify Correct Fuse Slots:
   • Constant Power Fuse (Yellow Wire): Use a multimeter to find a fuse that provides continuous power even when the ignition is off.
   • ACC Fuse (Red Wire): Use a multimeter to find a fuse that provides power only when the ignition is in the ACC position (engine on).

   Note: Do not insert fuses into slots that serve other critical functions.

4. Install Add-A-Fuse Taps: Remove the original fuse from the identified slots. Insert the original fuse into the lower slot of the add-a-fuse tap. Insert the provided dash cam fuse (usually 5A) into the upper slot of the add-a-fuse tap. Connect the red wire to the ACC tap and the yellow wire to the constant power (B+) tap.
5. Connect Ground Wire: Loosen a metal bolt or screw on the vehicle's chassis. Slip the black ground wire's ring terminal under the bolt/screw and tighten it securely. Ensure a good metal-to-metal connection for stable grounding.
6. Connect to Dash Cam: Plug the USB Type-C connector of the hardwire kit into your dash cam's power input port.
7. Test the Dash Cam: Turn on your vehicle's ignition to ensure the dash cam powers on. Turn off the ignition and check if the dash cam enters parking monitoring mode (if enabled in dash cam settings).
8. Route Cables: Use the wiring trim tool to neatly tuck the cables along the vehicle's A-pillar and headliner to conceal them. Use adhesive cable organizers to secure any loose wires.

6. Operating Instructions

6.1 24/7 Parking Monitoring

Once the hardwire kit is correctly installed and your dash cam's parking mode feature is enabled, the dash cam will automatically switch to parking monitoring when your vehicle's ignition is turned off. This allows for continuous surveillance, recording events like collisions (G-sensor detection) or time-lapse footage.

6.2 Low Voltage Protection

The hardwire kit continuously monitors your car battery's voltage. If the voltage drops below the preset threshold (e.g., 11.8V for 12V systems), the kit will automatically cut off power to the dash cam. This prevents excessive battery drain, ensuring your vehicle has enough power to start the engine.

7. Maintenance

• Regularly check all connections to ensure they are secure and free from corrosion.
• Ensure the hardwire kit and dash cam are free from dust and debris.
• If you notice any issues with power supply or parking mode functionality, re-check the fuse connections and wire integrity.

8. Troubleshooting

8.1 Dash Cam Does Not Power On

• Check all wire connections: Ensure the Red (ACC), Yellow (B+), and Black (Ground) wires are properly connected to their respective points in the fuse box and chassis.
• Verify fuse integrity: Check both the original fuse and the dash cam fuse within the add-a-fuse tap. Replace if blown.
• Confirm correct fuse slots: Ensure the ACC wire is connected to a fuse that powers on with the ignition, and the B+ wire is connected to a constant power fuse.
• Dash Cam Compatibility: Ensure your dash cam is compatible with a Type-C power input.

8.2 Parking Mode Not Activating

• Dash Cam Settings: Confirm that parking monitoring is enabled in your dash cam's settings and configured for G-sensor or time-lapse mode.
• ACC Wire Connection: The ACC (Red) wire must be correctly connected to a fuse that loses power when the ignition is off. If only the B+ (Yellow) wire is connected, the dash cam may boot directly but parking monitoring will not activate as it won't detect the ignition status change.
• Low Voltage Cut-off: If the car battery voltage is already below the set cut-off threshold, the hardwire kit will not supply power, preventing parking mode activation.
