Viofo A139 PRO 2CH | Capture 4K Ultra HD Video From Front & 1080p Rear
Viofo A139 PRO 2CH | Capture 4K Ultra HD Front Video & 1080p Full HD Rear Video

The A139 2CH PRO features a front and rear camera setup and is an upgrade to the previous model, the A139 2CH. This upgrade allows you to capture front-facing video footage at a stunning Ultra-HD 4K resolution, while the rear camera records at an always crisp Full-HD 1080p. This model is also one of the first dash cams to include the new Sony STARVIS 2 sensor. Combine these new features with Viofo's Night Vision 2.0 technology, and you get the clearest possible image of important details such as license plates and street signs in both daylight and at night.

The A139 2CH PRO also features built-in GPS tracking, faster dual-band Wi-Fi, voice notifications, a 300° rotatable front lens,  and more!

Crisp 4K HDR Recording

The first to deploy the newest Sony STARVIS 2 tech, the A139 Pro is powerful enough to beat most 4K dashcam competitors, offering enhanced clarity for important details such as license plates, signs, and pedestrians.

New Sony STARVIS 2 IMX678

Sony's latest technology features the STARVIS 2 IMX 678 image sensor, offering a wider dynamic range in a single exposure than the same-sized STARVIS pixel. This brings improved image quality with reduced noise and motion blur during day and night recording.

Night Vision 2.0

Night vision has always been a struggle with most dashcams. The A139 Pro has significantly improved this feature. With its type 1/1.8" image sensor, larger pixels can capture more light under the same illumination level, while the 4K HDR technology helps balance over-dark and over-bright areas to accurately restore 4K details during night recording.

4X Faster 5GHz Wi-Fi

A139 PRO is built with an upgraded 5GHz Wi-Fi connection module, offering the fastest ever Wi-Fi data transfer to ensure smooth video preview, download, and sharing.

GPS Logger

While video evidence will give you a clear advantage in any dispute, increase your odds with the built-in GPS logger, which records speed, time, and route data to the video file, allowing compatible viewers to display the data on playback. This is also a great option for parents of teen drivers or anyone needing record of their whereabouts.
