Freexar AC3X USB-C Dash Cam Hardwire Kit

Keep Your Dash Cam Protected Even While Parked

The Freexar USB-C Dash Cam Hardwire Kit connects your compatible dash cam directly to the vehicle’s fuse box, providing a clean and reliable power solution without occupying the cigarette lighter socket.

With smart ACC detection, parking mode support and built-in low-voltage protection, it helps your dash cam continue protecting your vehicle while parked without placing unnecessary strain on the car battery.

24/7 Parking Mode Support

Keep your vehicle under watch after the engine is turned off. The hardwire kit supplies continuous power to compatible dash cams that support parking recording, helping capture impacts, movement and unexpected events while you are away.

Actual parking recording functions depend on the connected dash cam model and its parking mode settings.

Smart ACC Detection

The three-wire ACC design allows a compatible dash cam to recognize the vehicle’s ignition status automatically.

• Engine off: The dash cam switches to Parking Mode.

• Engine started: The dash cam returns to normal driving recording.

There is no need to connect or disconnect the power cable each time you drive.

Low-Voltage Battery Protection

Built-in voltage detection helps protect your vehicle battery from excessive discharge.

The hardwire kit automatically cuts power when the battery voltage falls below:

• 11.6V for 12V vehicle systems

• 23.2V for 24V vehicle systems

This helps reduce the risk of battery drain during extended parking periods.

Compatible with 12V and 24V Vehicles

The kit supports common 12V and 24V electrical systems, making it suitable for many cars, SUVs, pickup trucks, vans and commercial vehicles.

It converts the vehicle’s 12V–24V power supply to a stable 5V output for compatible USB-C dash cameras.

Clean, Hidden Installation

Connect the dash cam directly to the vehicle fuse box and route the cable behind the headliner and interior panels for a clean, factory-style installation.

The 3.5-meter cable provides flexible routing options for different vehicle sizes and dash cam mounting positions while keeping the cigarette lighter socket available for other devices.
