Top Dash Cam Hardwire Kit Options in the UK

A dash cam is an invaluable tool for recording incidents on the road, but its protection shouldn't stop when you park. For many UK drivers, the peace of mind that comes from 24/7 vehicle surveillance is essential. However, your car's standard 12V power socket typically switches off with the ignition, leaving your dash cam powerless.

This is where a dash cam hardwire kit becomes a crucial accessory. It connects your camera directly to the car's battery via the fuse box or OBD port, providing a constant power source. This enables features like parking mode, which can automatically record bumps, motion or acts of vandalism when you're away from your vehicle.

This guide will walk you through the key considerations when choosing a kit and present our top recommendations to help you find a reliable 24/7 dash cam power supply for your needs.

How to Choose the Right Dash Cam Hardwire Kit

Selecting the correct kit involves more than just matching the plug. Here are a few practical points to consider to ensure safety, compatibility and performance.

1. Installation Method: Fuse Box vs. OBD Port

Your two main options for drawing power are the fuse box and the On-Board Diagnostics (OBD) port.

• Dash Cam Fuse Box Kit: This is the traditional method. It involves routing a cable from your dash cam to the vehicle's fuse box and tapping into specific circuits—one for constant power and one that is only active when the ignition is on. This allows the kit to intelligently switch between driving and parking modes. While it provides a very tidy, hidden installation, it does require a bit more effort and comfort working with your car's electrical system.
• OBD Dash Cam Power Cable: This is a simpler, plug-and-play alternative. The cable plugs directly into your car's OBD-II port, which is usually located under the dashboard. It's a quick and easy DIY solution that requires no wire tapping. The main consideration is ensuring the port's location allows for neat cable management and that it doesn't interfere with garage servicing.

2. Low Voltage Protection is Non-Negotiable

The most critical safety feature of any hardwire kit is dash cam low voltage protection. A continuous recording power cable draws a small amount of power from your car's battery to keep the dash cam in standby. Without protection, this could eventually drain the battery, leaving you unable to start your vehicle.

A quality kit constantly monitors the battery's voltage. If it drops below a preset threshold (e.g., 11.8V or 12.0V), the kit will automatically cut power to the dash cam, preserving enough charge to start the engine. Some advanced kits even allow you to adjust this cut-off voltage.

3. Check Your Connections and Compatibility

As dash cam technology has evolved, so have the power connections. Many modern cameras now use a USB Type-C port for power and data. It is vital to ensure you purchase a type-c hardwire kit if your dash cam requires it. Always check the product specifications for both the hardwire kit and your dash cam to confirm compatibility, not just with the connector type but also with the specific camera model.

Recommended Dash Cam Hardwire Kits

Here are a few standout options that offer reliable performance and essential safety features for UK drivers.

Botslab Dash Camera Smart Hardware Kit Type-C

• Why It Stands Out: This kit is the official accessory for the Botslab G980H series, ensuring seamless integration and performance. It enables an intelligent dash cam parking mode kit that can be configured for either 24-hour time-lapse recording or to start recording only upon collision detection, offering flexible protection. The generous 9-foot cable length provides ample flexibility for routing wires discreetly in most vehicle types.
• Pros:
  • Designed specifically for Botslab G980H, G980HPro, 3-Channel and 4-Channel models.
  • Features reliable under-voltage protection to prevent car battery drain.
  • Provides a stable 5V/2.4A output for consistent camera operation.
  • Simple three-wire installation process (ACC, VCC and GND) with clear instructions.
• Who is it for: Owners of a compatible Botslab dash cam who want a manufacturer-approved solution for a clean, professional and reliable 24/7 power setup.

70mai 4G Hardwire Kit UP04, Type-C

• Why It Stands Out: The UP04 does more than just power your dash cam; it brings it online. By adding a 4G SIM card (not included), this kit unlocks a suite of smart features. It enables remote live viewing via the 70mai app, sends instant notifications to your phone if a collision is detected and provides real-time GPS tracking of your vehicle's location.
• Pros:
  • Enables 4G connectivity for remote monitoring and alerts.
  • Built-in G-sensor detection triggers automatic recording and app notifications.
  • Smart dash cam low voltage protection safeguards your car battery.
  • GPS functionality allows for real-time vehicle tracking.
• Who is it for: 70mai dash cam users (compatible with A810, A510, Omni, etc.) who want the ultimate in vehicle security, including remote access and real-time alerts, transforming their dash cam into a fully connected security system.

KAWA Dash Cam OBD Power Cable

• Why It Stands Out: This kit's main advantage is its simplicity. As an OBD dash cam power cable, it offers a true plug-and-play experience. There is no need to identify fuses or tap into wires; simply plug the adapter into your vehicle's OBD port. It still provides the core functions needed for parking mode, including ACC detection to switch modes automatically and multi-level low voltage protection.
• Pros:
  • Extremely simple plug-and-play installation via the OBD-II port.
  • Features 3-level adjustable low voltage protection for added control.
  • Automatically detects ignition status to enable parking surveillance.
  • Equipped with a Type-C connector for modern dash cams.
• Who is it for: Car owners who prioritise a quick, easy and reversible DIY installation without the need to interact with the vehicle's fuse box.

Frequently Asked Questions

Do I need a hardwire kit for parking mode?

Yes, in almost all cases. Standard parking mode features require a constant power supply to monitor for incidents when the car is off. A 24/7 dash cam power supply, such as a hardwire kit, is designed to provide this, as the car's 12V accessory socket typically loses power when the ignition is turned off.

Will a dash cam hardwire kit drain my car battery?

A quality kit is specifically designed to prevent this. All reputable hardwire kits include a feature called dash cam low voltage protection. This system monitors your car battery's charge and will automatically shut down the power supply to the dash cam if the voltage drops to a pre-set safe level, ensuring you always have enough power to start your engine.

Can I install a dash cam fuse box kit myself?

Many vehicle owners with some confidence in DIY tasks can successfully install a dash cam fuse box kit. The products generally come with instructions, and there are many online tutorials available. However, it does involve working with your vehicle's electrical system. If you are not comfortable or familiar with this, we recommend seeking professional installation from a qualified auto electrician for safety and peace of mind.
