Record Front, Rear and Inside

The VIOFO A139 3-CH offers complete recording coverage of your vehicle - making it the perfect dash cam solution for rideshare and anyone else who wants to record what happens inside the vehicle in addition to front of and behind.

Capture the front, rear and interior of your vehicle with wide-angle lenses: 140° front, 170° rear and 170° interior.

Clear Vibrant Colours with Rich Details

Equipped with a 5MP Sony STARVIS image sensor, the A139 front camera captures the road ahead at 2K QHD at 30/60FPS. You get sharper, higher quality video with key details in all lighting situations. 140° viewing angle offers wide shooting coverage with minimal edge-to-edge distortion.

Pair it with the rear camera for a combined 310° comprehensive coverage all-around so you don't miss a thing. Both the rear and interior camera records in 1080p Full HD at 30FPS.

Infrared Interior Camera

The interior camera records in-cabin activity in 1080p Full HD at a 170° field of view. Also equipped with the Sony STARVIS image sensor and comes with 6 infrared LED lamps, allowing the camera to record cabin activity even in complete darkness. The inconspicuous infrared LEDs automatically activate based on the ambient light.

Voice Prompts for Complete Hands-Free

Keep your hands on the wheel and your eyes - you can now get voice notifications and alerts (in English) should there be any problems with the camera, for example, memory card failure. With voice prompts, you also get an audible confirmation of setting changes such as turning on/off audio recording.

No more fiddling with the buttons on the dash cam just to figure out what the continuous beeping alerts are trying to tell you.

Keeps Watch When You're Away

With motion and impact detection parking mode, the A139 3-CH protects your car, recording videos when it detects movement or impact, even when you're not there. Buffered parking mode is supported on the A139-3CH.

You will need the new VIOFO HK-3C Hardwiring cable or an external battery pack (such as the BlackboxMyCar BI-750 Dash Cam Battery Pack) to enable this feature.


Built-in Dual-Band WIFI and Mobile App

Say goodbye to taking the memory card in and out of the dash cam every time you want to review a footage clip. The A139's built-in Dual-Band Wi-Fi to let you connect with the free VIOFO App to control dash cam settings and access footage clips on the spot. Full control at your fingertips.

Alternatively, you can plug the microSD card into your computer and use a desktop viewer to manage your footage.

New Ultra-Slim Cable and Connectors

The A139 uses super-slim coaxial cables and miniature connectors for the interior and rear cameras. This ensures an easier and more discrete installation than traditional cable types.

The A139 also uses the USB-C Charging Cable, which is reversible and thus makes installation easier while providing a more reliable and stable power supply to the dash cam.

Gun O. (Toronto, CA)
Very good 3-channel cam at a reasonable price

This was the second cam I installed in my Subaru Legacy sedan - my first, a Campark/Cambase DC40, didn't work out very well. So I already knew my way around routing the wiring in my car, which is without any forward-facing driver assist cams or sensors and the attendant housing for them behind the mirror. This made my installation comparatively easy. The A139 works flawlessly and the video quality is excellent - on a par with Blackvue and Thinkware cams that cost much more, judging by the reviews I've seen on Youtube (including the ones by Blackboxmycar.) The separate interior camera makes for a slightly less tidy installation but gives great flexibility in finding a mounting location for it. The skinny, slightly stiff coax wiring for the interior and rear cams makes for a very easy and neat installation, but from what I've read, some people with early A139s last year had trouble with getting reliable connections to those cameras - the typical symptom seemed to be loose connectors on the A139 main camera. No problems like that for me. I would recommend the A139 based on my own experience with it.

Lucy W. (Kingston, CA)

Great, relatively easy to set up (actual set up took less than 5 minutes, but it took me about an hour to do the complete set up including hiding wiring in my car) and overall happy with the quality. Only wish that all the cameras were 60fps.

Tarunvir B. (Calgary, CA)
Excellent hardware, mediocre app

I am overall happy with my purchase. The video quality is great. The mobile app could use some updating though. Slow transfers over wifi, random disconnects in the middle of a transfers, etc. Definitely happy with the videos thenselves though
