Being the first to deploy the newest Sony Starvis 2 technology, the A139 Pro is powerful enough to outperform most 4K dashcam competitors with significantly upgraded image clarity and accuracy in license plate capturing. The latest Sony 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, resulting in much less noise and motion blur during day and night recording. Night vision has always been a challenge with dashcams, but it is highly optimized in the A139 Pro. The image sensor type 1/1.8’’ with larger pixels captures more light under the same illumination level, and the 4K HDR technology balances dark and bright areas to help accurately restore 4K details recorded at night. Built with a super slim coaxial cable and miniature connectors, the A139 Pro enables a more user-friendly, hidden installation and better electromagnetic interference reduction. An upgraded 5GHz Wi-Fi connection module is integrated into the A139 Pro to provide four times faster Wi-Fi data transfer, ensuring smooth video previewing, downloading, and sharing.
