Dash cams are becoming a must-have for drivers who want security, accident evidence, and peace of mind on the road. While many dash cams plug directly into the cigarette lighter socket, a hardwire dash cam kit offers a cleaner, more reliable, and feature-packed solution.

What Is a Hardwire Dash Cam Kit?
A hardwire dash cam kit is an installation accessory that connects your dash camera directly to your vehicle’s fuse box instead of relying on the cigarette lighter socket. This provides continuous power to the dash cam, even when the car is turned off—unlocking features like parking mode.
Most kits come with:
- A power cable (often micro-USB, mini-USB, or USB-C depending on the dash cam)
- Fuse tap adapters (to safely connect to the fuse box)
- A voltage cut-off system (to protect your battery from draining)
Why Use a Hardwire Dash Cam Kit?
1. Enable Parking Mode
With a hardwire kit, your dash cam can record while the car is parked, capturing hit-and-runs, vandalism, or theft attempts.
2. Cleaner Installation
No dangling wires in the cabin. The kit hides cables behind panels for a factory-finish look.
3. Always-On Power
The dash cam powers up automatically when you start the car and can stay active when parked.
4. Battery Protection
Quality hardwire kits include low-voltage cut-off features to prevent your car’s battery from draining.
How Does a Hardwire Dash Cam Kit Work?
The kit taps into your vehicle’s fuse box using fuse taps or add-a-circuit adapters. It typically connects to:
- Constant fuse (always has power): For parking mode.
- Switched fuse (only on with ignition): For regular driving use.
- Ground wire: Attached to the vehicle chassis for stability.
Once installed, the dash cam will automatically switch between driving and parking modes, depending on whether the ignition is on or off.
How to Install a Hardwire Dash Cam Kit (Step by Step)
⚠️ If you’re not comfortable working with your vehicle’s fuse box, it’s best to hire a professional installer.
- Locate the fuse box (often under the dashboard or glove compartment).
- Choose fuse slots—one constant power fuse and one ignition-switched fuse.
- Insert fuse taps provided in the kit.
- Connect the ground wire to an unpainted metal bolt or chassis ground point.
- Route the cable neatly around the windshield trim to the dash cam.
- Test the dash cam by turning the ignition on/off to ensure proper switching between modes.
Things to Consider Before Buying a Hardwire Dash Cam Kit
- Compatibility: Check if the kit matches your dash cam’s power connector (mini-USB, micro-USB, or USB-C).
- Voltage cut-off: Ensure it includes adjustable battery protection.
- Fuse type: Kits usually come with multiple fuse tap sizes (ATO, Micro2, Mini, etc.)—make sure yours fits your car.
- DIY vs. professional install: A DIY install is possible, but professional wiring guarantees safety.
