The GKU ACC Hardwire Kit keeps your compatible dash cam powered after the engine is turned off, allowing parking monitoring to continue while your vehicle is unattended.

Built-in ACC detection automatically recognizes the vehicle's ignition status:

Engine On → Driving Recording
Engine Off → Parking Monitoring

Compatible with 12V–24V vehicle electrical systems, including cars, SUVs, EVs, trucks, vans and buses.

Depending on your dash cam model, parking monitoring may include:

G-Sensor Collision Detection
Automatically starts recording when an impact or sudden vibration is detected.

Time-Lapse Recording
Records continuously at a lower frame rate to capture longer parking periods while reducing storage and power consumption.

Designed for compatible USB-C dash cams, the GKU ACC Hardwire Kit delivers stable 5V/3A power for reliable recording and parking monitoring.

The GKU ACC Hardwire Kit includes multiple built-in safety protections to help provide stable power while reducing the risk of excessive battery drain.

• Low-Voltage Protection
  
• Over-Current Protection
  
• Short-Circuit Protection
  
• Reverse Connection Protection
  
• Overheat Protection
  

When battery voltage drops to approximately 11.6V for 12V vehicles or 23.5V for 24V vehicles, the hardwire kit automatically cuts power to help preserve enough battery power to start your vehicle.

Note: This kit is not compatible with Mini USB or Micro USB dash cameras and is not recommended for vehicle electrical systems above 24V.
