4K Ultra HD Recording

Being the first to deploy the newest Sony STARVIS 2 tech, A139 Pro is powerful enough to outbeat most 4K dashcam competitors with immensely upgraded image clarity and accuracy in license capturing.

Sony STARVIS 2 IMX678

Sony latest technology STARVIS 2 IMX 678 image sensor, type 1/1.8’’, offers a wider dynamic range in a single exposure than the STARVIS pixel of the same size, bringing much less noise and motion blur during day & night recording.

4K HDR | Night Vision 2.0

Night vision has always been a headache with all dashcams, but is highly optimized in A139 Pro. Image sensor type 1/1.8’’ with larger pixel brings in more light under same illumination level and 4K HDR tech balances over dark and over bright areas to help accurately restore 4K details recorded at night.

User-friendly Installation

Built with super slim coaxial cable and miniature connectors, A139 PRO enables more user-friendly, hidden installation and better electromagnetic interference reduction.

4X Faster 5GHz Wi-Fi

An upgraded 5GHz Wi-Fi connection module is built into A139 Pro to provide 4 times faster Wi-Fi data transfer, ensuring smooth video previewing, downloading and sharing.

Voice Notification

A139 Pro supports multiple languages and clearly notifies you of settings changes
or memory card errors, keeping you fully focused on the road.

GPS Logger

A139 Pro provides detailed location, speed and time data of the vehicle when playing back the video on VIOFO App or computer.

*If you use the VIOFO App to play back the video and view GPS map, please download the video first.

CPL Filter

A circular polarizing lens (CPL) filter can be used to reduce reflections and glare off glass and road surfaces, bringing significantly improved image clarity and contrast.

Optional Accessories

External Microphone

The A139 series supports the use of external microphones, which are ideal for recording conversations, traffic accidents and potentially police misconduct.

Bluetooth Remote Control

The Bluetooth Control can be positioned in a convenient location for safe and easy use while driving. Pressing the button will instantly protect current video clip and image. Control Distance: 5 meters.
