Reviews

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.

Infrared Cabin Night Vision

Built with F1.6 aperture, 7 elements glass lens, the interior camera features six infrared LED lights, allowing the camera to record in details even in complete darkness.

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
