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.
3 Parking Surveillance Modes
The A139 PRO will automatically activate parking surveillance
mode when you turn off the ignition providing
video evidence of mishaps like hit-and-runs while you’re away from your vehicle.
* Optional VIOFO HK3-C Hardwire Kit Required For Parking Mode
Auto Event Detection Mode
The camera will automatically record for 45 seconds while moving objects are detected while parked.
Low Bitrate Recording Mode
This mode records video in low bitrate 4Mb/s for both front and rear. It keeps recording continuously in mini file size with audio recorded.
Time Lapse Mode
Time-lapse allows you to record a video at your choice of lower framerates (1 / 2 / 3 / 5 / 10 fps) while parked, saving space on the memory card.
300° Rotatable Lends
The front 4K camera lens provides nearly 300° of smooth rotation, allowing an optimal viewing angle in multiple mounting positions. This can even be used for vlogging with the lens turned inward to face the occupants of the vehicle.
Voice Notification
Keep your eyes on the road while the A139 informs you of any vital information such as settings changes or errors. Supports English and multiple other spoken languages.
User-friendly Installation
The A139 PRO now utilizes super slim coaxial cable and miniature connectors for the rear camera cable, making it easier for users to install it discreetly along the vehicle paneling and through cable conduits, etc, and also reduces any electromagnetic interference.
CPL Filter
Using a circular polarizing lens (CPL) filter, included at no extra cost, can diminish reflections and glare on glass and road surfaces, resulting in noticeably enhanced image clarity and contrast.
