Triple-Channel with the new Sony STARVIS 2 Technology

The VIOFO A139 Pro 3CH is the first triple-channel dash cam to use the newest 8MP Sony STARVIS 2 technology - supporting up to 140° FOV at 4K UHD in the front camera, and 170° Full HD 1080P for both rear and interior cameras.

Super Slim Cable for Easy Installation

For easier installation, the A139 Pro 1CH now comes with 2.8m ultra-thin coaxial cable and miniature connectors.

When compared to traditional rear cables, it is simpler to install and can be better hidden on the car roof! This reduces the electromagnetic interference to other in-car electronic devices such as car multimedia systems.
