VIOFO A129 Pro Duo 4K 2-Channel Dash Cam with GPS

Small price tag, big impact. The advanced 8.29MP Sony image sensor to deliver some of the best 4K UHD (front) and Full HD (rear) we have seen. Throw in great features like buffered parking recording, built-in dual-band WiFi, a 2.0" high-definition screen and more, the A129 Pro Duo easily and deservingly takes the title of Best Budget-Friendly 4K Dual-Channel Dash Cam 2020.

Front & Rear


GPS Included

Up to 5GHz Wi-Fi

Built-in Screen

Parking Mode

Clear Vibrant Colours with Rich Details

Equipped with a 8MP Sony Exmor R STARVIS image sensor, the A129 Pro Duo captures clear vibrant colours with right detail in 4K UHD in the front and Full HD in the rear camera in all light situations. The front camera captures in 130° and the rear camera in 140° so you don't miss a thing, day or night.

Keeps Watch When You're Away

With buffered parking mode, the A129 Pro Duo protects your car, recording videos when it detects movement or impact, even when you're not there. Buffered recording even includes the few seconds before and after the triggered event, so you get the complete picture.

You will need a 3-wire Hardwiring cable or an external battery pack (such as the Cellink NEO Battery Pack) to enable this feature.

Add Speed and Location Data to Your Videos

This A129 Pro comes with the external GPS module. With the GPS, you can record your speed and route data in your video footage files. The GPS will also synchronize the A129 Pro’s clock with the GPS time so that your video files can be correctly time-stamped.

Did you know that your footage with speed and location information can be used a defense if you believe you received the ticket in error.

Full Control at Your Fingertips

Say goodbye to taking the memory card in and out of the dash cam every time you want to review a footage clip. The A129 Pro's built-in Wi-Fi to let you connect with the VIOFO App to control dash cam settings and access footage clips on the spot. Full control at your fingertips.

With ultra fast dual-band built-in wi-fi & GPS, you'll know what's happened in blazing speed. Download your footage through 5GHz wi-fi, literally 2X faster than other dash cams running on 2.4 GHZ wi-fi.

Excellent Video Quality but I do need something to stop dash-board reflections

It works

The drivers in Florida are some kinda cheeks bro. But this camera gets the cars, the plates, and the driver in the act if the outside isn't dark. If it lasts long even with the heat, 10/10.

Great camera but BMWs beware!

The quality of the camera is very good, it's my second camera from Viofo, but the but problem now is that modern BMWs (I have an X6M) will get the battery drained. I go to the same place to have my dashcams installed and I am the second BMW to have an unusual high lever of draw on the car in parking mode. If you hardwire, and unplug the camera when you park overnight, there is still a little draw. You'll have to be creative or figure out a battery solution or get used to plugging it in every time you get in the car. Given the lockdowns, not driving the car for two weeks is a great possibility for me. Also for some BMW Alcantara headliners, there is not enough cable to mount the rear camera. I'll probably give this camera to my cousin and buy another that supports a battery pack. BBMC did a great job, I am a happy customer.
