Choose the exact hardwire kit for your camera
Confirm voltage compatibility, connector type, parking-mode support, and the maker's recommended cutoff options. Read both the camera instructions and the vehicle manual before opening the fuse panel.

How Do You Hardwire a Dash Cam Safely?
Use the camera maker's compatible hardwire kit, an appropriate fused circuit, a secure chassis ground, and a conservative low-voltage cutoff. If the fuse layout or airbag-safe routing is unclear, use a qualified installer.
Plan the camera position and cable route
Place the camera where it has a clear view and complies with state rules. Map a route that stays clear of curtain airbags, pedals, steering components, sharp edges, and moving trim.
Identify switched and constant circuits
With the ignition in the required states, use an appropriate circuit tester or multimeter to identify an accessory circuit and, if parking mode needs it, a constant-power circuit. Do not rely only on a fuse label or wire color.
Install correctly sized fuse taps
Use the fuse-tap type that matches the vehicle. Keep the vehicle's original fuse in its protected position and fit the hardwire-kit fuse as directed; tap orientation matters because the supply side must be identified.
Make a secure ground connection
Attach the ground lead to a manufacturer-approved chassis grounding point or suitable unpainted metal point. A loose or painted connection can cause intermittent operation.
Set battery protection and test every mode
Choose the low-voltage cutoff and timer according to the kit, vehicle, and expected parking duration. Test normal startup, shutdown, parking entry, saved clips, and any warning lights before replacing trim.
Common questions
Questions before you buy
How do you hardwire a dash cam?
Connect a compatible fused hardwire kit to the correct switched and, when required, constant circuits, secure its ground, route the cable safely, set battery protection, and test each recording mode.
Can I hardwire a dash cam myself?
Only if you can identify the circuits and safe cable route with the proper tools and vehicle documentation. Otherwise, professional fitting is the safer choice.
Which fuse should I use for a dash cam?
Use an eligible circuit approved for accessory tapping in your vehicle and avoid safety-critical systems. The correct choice is vehicle-specific and must be confirmed by testing and documentation.
Will hardwiring a dash cam drain the battery?
Parking mode uses battery power. A working low-voltage cutoff and timer reduce the risk, but an aging battery, long parking periods, cold weather, or an unsuitable setting can still cause problems.
Does a hardwired dash cam record when the car is off?
It can if the camera, kit, wiring, and settings support parking mode. Some systems record continuously; others wake for impact, motion, or time-lapse events.
