Frequently Asked Questions

Is the VIOFO A129 Pro Duo still a good 4K dash cam?
Yes. The A129 Pro Duo records true 4K 3840x2160 on the front and Full HD 1080P on the rear, providing clear dual-channel footage. While it uses previous-generation Sony sensors (IMX317 front, IMX291 rear), it remains a solid choice for budget-minded drivers who want 4K front recording at a lower price point than current-generation systems.
What is the difference between the A129 Pro Duo and the A229 Pro 2CH?
The A229 Pro 2CH is the current-generation successor. It features the newer Sony STARVIS 2 sensors with significantly improved dynamic range and HDR performance, 5GHz Wi-Fi (versus dual-band on the A129), and a modular design that supports expansion to 3 channels. The A129 Pro Duo offers 4K front recording at a lower price for buyers who prioritize budget over the latest sensor technology.
Does the A129 Pro Duo have Wi-Fi and GPS?
Yes. The A129 Pro Duo includes dual-band Wi-Fi for wireless file transfer and settings adjustment via the VIOFO app, plus built-in GPS to log your speed and location on every recording.
Can the A129 Pro Duo record both cameras simultaneously?
Yes. The A129 Pro Duo records from both the front (4K) and rear (1080P) cameras simultaneously. Both video files are saved with synchronized timestamps, providing complete coverage of any incident from two angles.
Does the A129 Pro Duo support parking mode?
Yes. The A129 Pro Duo supports parking mode with motion detection and impact detection via the built-in G-sensor. A hardwire kit (sold separately) is recommended to provide constant power to the camera while your vehicle is parked without draining the car battery.
