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.

Amazing new sensor that produce incredible daytime footage I think rivial the image quality of those popular action cameras. Top norch dynamic range and color plus real 4k resolution. But the weird light leak effect under artificial lights make the night time footage a bit overwhelming. Overall great new model worth upgrade from any previous dashcams.

Excellent quality, Small form factor tucks right behind the rear view mirror and can't really be seen at all.
