Viofo A139 3-Channel Dash Cam Review (2022)

VIOFO is an innovator of quality electronics, and an excellent example of their expertise is their 3-channel dash cam, Viofo A139. There are many 3-channel dash cams on the market today, but the A139 is unique in that all three cameras are separate from each other. Where other models have the front-facing camera and interior-facing camera manufactured together in one unit, VIOFO decided to separate the two cameras giving you the option of placing them in different locations on your vehicle’s windshield. A versatile way of allowing for a better angle placement of your choice.Viofo A139 Dash Cam

The front-facing camera records video at a maximum 1440p (2K) resolution with a wide 140-degree field of view which limits annoying barrel distortion. Interior and rear cameras have an even wider 170-degree field of view recording at 1080p resolution. Viofo A139 utilizes a Sony 5MP STARVIS sensor (IMX335) which provides crystal clear video, essential for recording vehicles’ license plate numbers in low light conditions, affordable by Sony’s “Super Night Vision.”

Viofo A139 comes with a polarizing filter that attaches to the 300-degree rotating lens of the front-facing camera helps illuminate glare on those bright sunny days. The interior camera has, what is referred to as, “Infrared Night Vision.” This allows for recording in complete darkness protecting the driver, and passengers. All three cameras record to a maximum capacity of 256GB microSD card.

The A139 comes with dual-band (2.4 GHz & 5 GHz) built-in Wi-Fi, enabling you to view the live recording from all three cameras. You can also playback your recorded videos as well as download and share them with family and friends. The built-in Wi-Fi allows you access to all of the camera’s numerous setup options.

Using the system’s built-in GPS, you can log and time stamp your vehicle’s speed and location. In the setup menu, you can change the speed readout to either MPH or KPH.

The VIOFO A139 offers three parking surveillance options. The Auto Event Detection will start recording as soon as an event has been detected. In Buffered Parking Mode, recording will start a few seconds before and a few seconds after an impact has been detected allowing for enough coverage of the event. In Time Lapse Mode, the dashcam will take low frame rate snapshots, which will appear as a video during playback.

The lower bitrate allows for continuous recording of mini-sized files. To utilize parking surveillance, though, you will need to purchase separately the optional Viofo HK3-C hardwire kit which is specific to Viofo A139.

The A139 dash cam uses ultra-thin 6m coaxial cable, which makes installation so much easier than the typical thicker cables other dashcams use. The cables tuck away nice and easy as you route them to the various cameras. It also utilizes plug-in mini connectors making for a much tidier-looking installation.

In conclusion, the VIOFO A139 is a well-rounded dash cam system that will fully meet all of your needs, recording all events both inside and outside of your vehicle. A complete system especially useful to UBER and taxi cab drivers, not to mention the added enjoyment of watching your vacation videos. Your safety and fun package is all rolled up in one video recording system.
