Viofo A129 PRO Duo Dash Cam HK3 Hardwire Kit 128GB Bundle
Couldn't Load Pickup availability
This VIOFO A129 Pro Duo bundle combines the two-channel dash cam, recording Ultra HD 4K at the front and Full HD 1080p at the rear with a Sony IMX317 8MP sensor, dual-band Wi-Fi and GPS, with an HK3 hardwire kit, an 8-piece fuse kit and a 128GB microSD card.
The A129 Pro Duo needs the HK3 hardwire kit for buffered parking mode, and the fuse set makes fitting to the fuse box straightforward. The dash cam is also sold on its own or in a bundle without the memory card, and the VIOFO 128GB microSD card is available separately.

About the Viofo A129 PRO Duo HK3 Fuse Kit 128GB Bundle
From our tech experts at CEN
Everything for a front and rear install in one box: the Viofo A129 Pro Duo dash cam, the HK3 hardwire kit, an 8-piece fuse set and a Viofo 128GB high-endurance microSD card. The A129 Pro Duo records 4K at 3840 x 2160 ahead and Full HD 1080p behind, with dual-band Wi-Fi and built-in GPS.
Who it suits
Drivers who want two-channel 4K at a sensible price and would rather not match the hardwire kit and card themselves. The HK3 is the kit the A129 Pro Duo needs for buffered parking mode, which saves 15 seconds before and 30 seconds after a detected impact or motion event.
Our tech experts advise
The 128GB card is a good match for 4K front and 1080p rear recording. Format it in the camera on first use, and reformat every few months to keep it healthy. We fit 2-channel systems from £100 at our Beeston workshop, with the rear cable hidden behind the trim. See dash cam installation.

Frequently Asked Questions
Q: What SD card do I need for this dash cam?
A: Use a high-endurance microSD card designed for continuous recording. Standard cards wear out quickly in dash cams. CEN stocks suitable high-endurance cards, and the maximum supported capacity is listed in the Specification tab.
Q: Does this dash cam record while the car is parked?
A: Parking mode is listed in the Specification tab. Where supported, it requires constant power from either a hardwire kit or a dedicated dash cam battery pack, both of which CEN stocks.
Q: Do I need to hardwire the dash cam?
A: Not necessarily. All dash cams work from the 12V socket for drive recording. Hardwiring hides the cabling and enables parking mode, and CEN offers professional hardwire installation from our Nottingham premises.
Q: Will the footage be accepted by my insurer or the police?
A: Dash cam footage is widely used in insurance claims and can be submitted to most UK police forces through their online portals. Recording quality matters, so check the resolution in the Specification tab.
Q: Front only or front and rear - which should I choose?
A: A front camera covers the most common claim scenarios. A two-channel system adds rear coverage for rear-end collisions and tailgating evidence, which is where many disputed claims arise. Three-channel systems add an interior view, suited to taxi and fleet use.
Q: What is included in the A129 Pro Duo 128GB bundle?
A: You get the A129 Pro Duo front and rear cameras, 6m rear camera cable, car charger, Mini USB cable, GPS mount, two non-GPS mounts, cable clips and stickers, plus an HK3 hardwire kit, an 8-piece fuse kit and a 128GB microSD card.
Q: Is 128GB enough for the A129 Pro Duo?
A: Yes for everyday use. Loop recording overwrites the oldest footage automatically and locked event clips are kept until you delete them. The A129 Pro Duo supports cards up to 256GB.
Q: Why the HK3 hardwire kit?
A: The A129 Pro Duo uses a Mini USB power connection, so it takes the HK3 hardwire kit. The HK3 is required for buffered parking mode and motion detection.
