Uniden HWK-3 Adjustable Voltage Hard Wire Kit for USB-C Dash Cams 12V and 24V 3-Wire ACC Design with Battery Drain Protection
The Uniden HWK-3 is an adjustable voltage hard wire kit for dash cams with a USB-C connector, featuring an L-shaped USB-C plug and a 3-wire design including an ACC wire. Compatible with 12V and 24V vehicle electrical systems, it provides constant power to the dash cam even when the vehicle is turned off, while automatically cutting power when the battery voltage drops to a set threshold to prevent battery drain. Suited to Uniden smart dash cams with USB-C power input.
Product overview
A hard wire kit connects a dash cam directly to the vehicle's fuse box rather than relying on a cigarette lighter socket, allowing the dash cam to operate in parking mode without the ignition on. The 3-wire design connects to three circuits: constant 12V (always live), ACC (live only with ignition on) and earth. The ACC wire allows the kit to detect whether the vehicle is running or parked, enabling the dash cam to switch between driving and parking recording modes automatically.
The adjustable voltage cutoff monitors the vehicle battery and cuts power to the dash cam when the battery drops below the set threshold, preventing the dash cam from draining the battery flat during extended parking periods. The L-shaped USB-C plug keeps the cable low-profile at the dash cam connection point. The HWK-3 suits 12V and 24V vehicles.

Frequently asked questions
What is a hard wire kit used for? A hard wire kit connects a dash cam directly to the vehicle's fuse box, providing power for parking mode recording when the ignition is off. Unlike a cigarette lighter socket connection which loses power when the ignition is turned off, a hard wire kit keeps the dash cam powered from the vehicle battery, allowing it to record while parked.
What does the ACC wire do? The ACC (accessory) wire connects to a circuit that is live only when the ignition is on. The kit uses this to detect whether the vehicle is running or parked, allowing the dash cam to automatically switch between driving mode (ignition on) and parking mode (ignition off) recording.
How does the voltage cutoff protect my battery? The kit monitors the vehicle battery voltage continuously. When the voltage drops to the set cutoff threshold, it automatically cuts power to the dash cam, preventing it from draining the battery below a safe level. The cutoff voltage is adjustable to suit different battery types and usage requirements.
Which Uniden dash cams is this kit compatible with? The HWK-3 is designed for Uniden smart dash cams with a USB-C power input. Confirm compatibility with your specific Uniden dash cam model before purchasing.
Do I need an electrician to install a hard wire kit? Hard wire kits connect to the vehicle fuse box and require basic automotive electrical knowledge. If you are not comfortable working in the fuse box, installation by a qualified auto electrician is recommended.
