Frequently Asked Questions - A129 Pro Duo VIOFO
How do I install the VIOFO A129 Pro Duo?
Mount the front camera to the windshield using the adhesive mount, route the power cable to your car's lighter socket or hardwire kit. Mount the rear camera similarly and connect the cable to the front unit. Adjust camera angles and connect to the app via Wi-Fi for configuration.
What type of SD card is recommended?
A high-endurance MicroSD card with Class 10 / U3 speed rating is recommended, up to 256GB. For 4K recording, a card with write speed of at least 30 MB/s is advised (e.g., Samsung EVO Select, SanDisk High Endurance).
How do I enable parking mode?
Parking mode requires the hardwire kit (sold separately) to connect to your car's fuse box. In the camera settings, enable 'Parking Mode' and choose between time lapse, low bitrate, or motion detection recording. The camera will automatically switch when the ignition is off.
Can I view videos on my phone?
Yes, via the VIOFO app. Connect to the camera's Wi-Fi network (default password 12345678) and open the app. You can view live feed, playback recordings, and change settings. Wi-Fi range is approximately 10 meters.
How does the GPS work?
The built-in GPS module records your speed, coordinates, and route. This data is embedded in the video file and can be viewed using the VIOFO player or app. GPS accuracy is typically within 5 meters.
What is loop recording and how does it work?
Loop recording overwrites the oldest saved video when the SD card is full. The camera records in segments (1/3/5 minutes). Protected files (from G-sensor or manual) are not overwritten. Ensure the SD card is formatted in the camera.
What video resolutions are available?
Front: 4K(3840x2160)@30fps, 2K(2560x1440)@60fps, 1080p@60/30fps. Rear: 1080p@30fps, 720p@60/30fps. For dual recording, the default is 4K front + 1080p rear. Higher resolutions may reduce frame rate.
How is the night vision?
The Sony STARVIS sensor provides excellent low-light performance. At night, the camera uses Wide Dynamic Range (WDR) to balance exposures. For best results, ensure the windshield is clean and use the camera in daylight for reference.
How do I update the firmware?
Download the latest firmware from VIOFO's website. Copy the .bin file to the root of a formatted MicroSD card (FAT32). Insert the card into the camera and power on. The camera will auto-update (do not turn off). After update, delete the firmware file.
What is the warranty and how to get support?
VIOFO offers a 12-month warranty from the date of purchase. For support, contact VIOFO via their official website or authorized reseller. Keep your proof of purchase. Extended warranty may be available from some retailers.
