A119S Review


The A119S was introduced in Dec 2016 and under gone many changes to hardware and firmware causing much frustration for early owners. As of Feb 2019 it still uses the V2 GPS Mount and backplate contacts with EVA pad to improve stability and reliability. The Lens has changed 4 times, currently sold with narrower coated 130 FOV Lens. Viofo's Firmware updates to image quality went the wrong way in 2017 producing over-sharpened video. In August 2018 BCHobbyist created Modified Firmware reduced Sharpness, increased Bitrate, adjusted Saturation for improved image quality. Viofo has recently added new Sharpness Menu setting which was long overdue and welcomed with more useful options pending.

This was my favorite model until the A129 was mounted beside it for side by side comparison. If you want a budget priced 1080P low light sensitive Parking Mode capable Dash Cam the A119S is a great choice. It remains my daily driver for over 2 years.

A119S Setup Tips

New Dashcams should always be tested for image quality and overall camera functionality using the pre-installed firmware so vendor can't claim you damaged it with incorrect firmware. Record test footage even in your hand indoors or out window then keep this footage. Once Dash Cam passes functionality tests install in vehicle as per instructions. At this point if no Lens issues or obvious defects are noticed, you should install the most recent official Firmware.

This model attaches to windshield with single clip mount which requires applying foam pad to reduce mount vibration. This pad will deteriorate after about a year and begin requiring replacement.

The vehicle interior in full Sun in hot summer can reach damaging temperatures for any camera. The A119S Dash Cam will shut off at 75-80C, if you notice this behavior repeating internal damage will occur.

Most effective ways to reduce A119 Dash Cam heat is:
- avoid 60fps and use 30fps
- use 16-24 Mb/s Bitrate in hot summer
- don't use Parking Mode in full sun for hours
- remove any internal or external tape blocking cooling vents (see Tips#1 video below)

As part of regular Maintenance owners should :
- format micro SD card every 2 months.
- reset Default Settings after each Firmware Update.
- when powered from GPS module clean contact plate every 6 months.
- always insert & remove micro SD card while Dashcam is off.

Video Tutorials and Test Footage

A129 verses A119S compared image clarity, color saturation, brightness and low light sensitivity differences. Both Dashcams used the same 130FOV Lens, the color Saturation differences are most obvious on Bridge with A129 stock Saturation neutral while A119S produced realistic colors. Both VIOFO Dash Cams were using 26 Mb/s Bit Rate firmware.
