Only VIOFO A129 support rear camera.
The VIOFO A129 is a dual channel, dual dash camera unlike the previous VIOFO A119 and A119 Pro.
Instead of buying two cameras for the front and rear of your car, the VIOFO A129 allows you to buy one camera that performs better, has better features, and is less expensive than buying two separate A119 cameras.
Both front and rear cameras on the A129 setup provide 1080p HD video. If you’re only using the front camera then it can record at 60 fps but both cameras simultaneously record at 30 fps. It also has an F1.6 Aperture 7 Element glass lens in both cameras to prevent image distortion by glare and provide a sharper image.
