Fresh and New Features of the VIOFO A139 Pro 4K UHD
Triple-channel dash cam

While the A139 is capable of capturing footage in a 3-channel configuration, it only records 2K QHD for its front camera, and full HD for its rear and interior. If you’re a VIOFO fan and wanted 4K, the A129 Pro was an option, but unfortunately, it can only support up to two channels.

Now, with the VIOFO A139 Pro, you get the best of both the A129 Pro and A139’s worlds! Yes, the new VIOFO A139 Pro supports up to 4K UHD 3840 x 2160P front recording in all single, dual, and triple channel options.

Therefore, users who prefer full coverage in three-channel recording will no longer have to deal with front 4K downgraded to 2K as the A139 Pro 3CH is the first to support true 4K front + FHD interior + FHD rear recording. Definitely the best VIOFO for videos to date!

Safe to say, the VIOFO A139 Pro is truly a history maker. Why? Above the hundreds of dash cam models available in the market, it’s the VIOFO A139 Pro series that became the first in the industry to use the newest 8MP IMX 678 Sony STARVIS 2 technology which ensures improved low-light performance and contrast, higher resolution and clarity, and more efficient consumption in parking mode.

In addition to having a larger image size with a type of 1/1.8", the 4K A139 Pro series now has much less noise and motion blur during day and night recording, making license capturing ever better than before.

Love (or need) to drive during the night? You’ll surely like this next feature. VIOFO understands that night vision has always been an issue with dash cams, particularly 4K models. With the new A139 Pro, its 1/1.8" image sensor type with larger pixels captures more light under the same illumination level. Its groundbreaking 4K HDR tech also balances over dark and bright areas - automatically.

And if you want to take a look at what’s happening inside your car, what your driver or passenger do, the interior camera of the VIOFO A139 Pro will act as the CCTV for you. Through the A139 Pro’s F1.6 aperture, 7 elements glass lens, and six infrared LED lights, this dash cam records incidents inside the cabin in detail even in complete darkness, extremely useful for commercial and Uber drivers to avoid unnecessary disputes. The IR will also automatically adjust and turn on or off as needed, whereas plenty of other models out there just leave them on all the time. If leaving the LEDs always on is preferred, or always off, this can be configured in the settings as well.

For easier installation, the A139 Pro series now comes with 2.88mm ultra-thin coaxial cable and miniature connectors. When compared to traditional rear cables, it is simpler to install and can be better hidden on the car roof. This also reduces the electromagnetic interference to other in-car electronic devices such as car multimedia systems.

High-speed connection guaranteed. The A139 Pro series, like the recent A229 Duo, includes an upgraded 5GHz Wi-Fi module that provides 4 times faster data transfer, ensuring smooth video streaming, downloading, and sharing through the easy-to-use VIOFO mobile app available in Android and iOS devices.

Ensuring fuller video coverage, the all-new A139 Pro series' front 4K camera is designed with a 140-degree lens that can be rotated up to 300°, adapting better in different car models for optimal positioning. Now, you can easily switch the front lens to the cabin if you like to record your road trip adventures or want to include travel videos in your vlogs!

For user convenience, the A139 Pro series has been equipped with voice notification features to notify you of setting changes or memory card errors. Available in multiple languages, this feature allows you to remain focused on the road while being in the know of your drive and dash cam’s status. No more annoying beeping sounds! Bye!

Unlike most VIOFO dash cams like the A139, the A139 Pro series now includes a CPL Filter in its package. No more added cost in buying a CPL filter, as it's already FREE! This circular polarizing lens (CPL) filter can be used to significantly improve image clarity and contrast by reducing reflections and glare off glass and road surfaces, best paired with the BlackboxMyCar Aqua Shield all-weather protection guard. If this works on the A139, can you imagine how sharper and clearer the video will be with the 4K UHD and Sony STARVIS 2 powered A139 Pro?

And while 256 GB storage space might be big enough for some, VIOFO even leveled up the storage capacity of the A139 Pro, increasing the maximum SD card capacity to up to 512GB. It's rare to find dash cams compatible with memory cards up to 512GB, so the A139 Pro is another game-changer in this area!
