A129 Pro Duo Dash Cam Bundle
Ultra HD Real 4K Dash Cam
The A129 Pro Duo uses a Sony IMX317 8MP sensor to capture Ultra HD 4K at 3840×2160 at 30fps. 4K resolution is four times the detail of Full HD, making it easier to read street signs and licence plates from footage.
Upgraded Super Night Vision and WDR
The 8MP sensor, paired with a 7-glass F1.8 aperture lens and WDR (Wide Dynamic Range), automatically balances exposure in bright and dark areas to keep details like road signs and licence plates clear at night.
Built-in Wi-Fi and GPS
Dual-band 2.4GHz and 5GHz Wi-Fi reduces wireless interference, providing a more stable connection and faster file transfer to the VIOFO app.
The integrated GPS logs speed and location, automatically syncs time via satellite, embeds a timestamp in the video, and lets you review your route in the VIOFO app.
Buffered Parking Mode
Buffered parking mode saves 15 seconds of footage before a detected impact or motion event and 30 seconds after it, capturing the full context of any incident. This bundle includes the OP100 OBD-II cable, which provides the constant power this feature needs.
Premium Functions
Includes loop recording, emergency recording, motion detection, and time-lapse recording.
OP100 OBD-II Power Cable
The OP100 draws power from the vehicle OBD-II port, giving the dash cam the constant supply it needs for parking mode without tapping into the fuse box. It includes low-voltage protection to stop the car battery being run down.

About the Viofo A129 Pro Duo OP100 128GB Bundle
From our tech experts at CEN
The A129 Pro Duo in a ready-to-fit bundle: the Viofo dash cam with an OP100 OBD-II power cable and a 128GB microSD card. It records 4K at the front and 1080p at the rear through a Sony IMX317 8MP sensor, with dual-band Wi-Fi and GPS built into the mount.
Who it suits
Drivers who want parking mode without wiring into the fuse box, using the OBD-II port instead.
Our tech experts advise
Format the 128GB card in the camera on first use. Set the OP100 parking timer (3 hours, 24 hours or always on) to suit how long the car is usually left. We fit the A129 Pro Duo and its accessories at our Beeston workshop, with the cabling hidden. See dash cam installation.

Frequently Asked Questions
Q: Does this dash cam record while the car is parked?
A: Yes. Parking mode needs constant power, which this bundle provides through the included OP100 OBD-II cable.
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.
Q: What is included in the A129 Pro Duo OP100 + 128GB bundle?
A: You get the A129 PRO DUO Dash Cam, Car charger, Rear Camera Cable 6m, Mini USB cable, GPS mount, Non-GPS mount x2, Clips x5 and Stickers x2, plus an OP100 OBD-II power cable and a 128GB microSD card.
Q: Do I need a hardwire kit with the OP100?
A: No. The OP100 plugs into the OBD-II port and provides the constant power needed for parking mode, so a separate hardwire kit is not required.
Q: Is 128GB enough?
A: Loop recording overwrites the oldest footage automatically, so the card never fills up, and locked event clips are kept until you delete them. A 128GB card holds a good amount of footage for everyday driving.
