Features

  • Sony STARVIS 2 Real 4KA139 PRO 2CH with 2023 revolutionary STARVIS 2 IMX678 sensor on the front camera, the 4K resolution is superior to most exisiting 4K dash cameras. Featuring real 4K UHD Dual Channel Front and Rear, the dual dash camera is capable of recording videos in 4K front (2160P@30fps) and rear 1080P resolutions. It captures the license plate information clearly in motion both day and night.
  • 4K HDR Night Vision 2.0Adopting the most innovated STARVIS 2 IMX678 sensor with larger image pixel 1/1.8'', its superior sensitivity enables it to record sharp video, even in low light. In conjunction with an upgraded 7-Glass F1.6 aperture lens and HDR technology, A139 PRO provides a much clearer image at night than most dash cameras, maintaining a sharp image and automatically balancing the lighting over dark areas.
  • Faster 5GHz Wi-Fi & GPSAn upgraded 5GHz Wi-Fi connection module is built into the A139 PRO 2CH to provide the fastest Wi-Fi data transfer, ensuring smooth video previewing, downloading and sharing. The two channel dash cam can log the current speed and GPS location with GPS logger, and a time stamp can be embedded in the video.
  • Super Slim Coaxial Cable The A139 PRO Dash Cam 2 channel uses super slim coaxial cable and miniature connectors for the front and rear interface, making installation easier and more discreet than traditional cable types. Coaxial cable, according to testing, reduces the DAB interference phenomenon better than most car dashboard cameras.
  • 24H Buffered Parking ModeThe A139 PRO dash cam front and rear offers three parking modes 24 hours a day, seven days a week. When an event is detected, Auto Event Detection will start recording automatically. Time Lapse continuously captures a video at low frame rates such as 1/2/3/5/10/15 fps. Low bitrate continuous recording in a mini file. Parking mode is available for both front and rear cameras. The A139PRO series is suitable for the HK3-C hardwire kit. (B08TW9BBGB)
  • Anti-Glare CPL Included & Voice Notification The CPL (Circular Polarizing Lens) is mounted on the dashcam's front lens to reduce reflections and glare from glass and road surfaces, resulting in significantly improved image quality and contrast in many situations. When you set the car camera or the camera has an error while recording, it will speak in English to remind you of the camera's status, assist you in properly completing the setup wizard, and diagnose issues.
  • 18 Months WarrantyVIOFO dash cam A139 PRO 2CH comes with an 12-month warranty and lifetime technical support. For an extended warranty from 12 months to 18 months, you can also register the product information on our official VIOFO website.

  • Please note: A139PRO does not come with a memory card included. We recommend using a high-quality VIOFO memory card for optimal performance and reliability. The maximum supported capacity is 512GB, but we suggest using a 256GB memory card for optimal performance and stability.

    • Easy installation
I was able to quickly use a pole snake to get the camera cable from the back to the front to connect to the Camera. Then I ran the power wires for the hard wire kit down the front windshield pillar to the fuse box. I used the quick taps that I purchased and got battery & ACC power for the camera. I formatted the 256 GB SD card and installed it. It is a little difficult to install the SD card as I had to use a small screwdriver to fully get it to click into the Camera. The Camera video is good unless the sun is very bright and low in the sky. The app works great but you have to stop recording to access the videos. You can watch live video on your device which can be distracting. I have a mobile hot spot in my car so if I connect to the camera I can not access the internet on my phone. I have to disconnect from the camera to get internet back on my phone. Not a big deal but its an annoyance. Overall great product purchase. ... show more

The Viofo A139 Pro is unmatched in video quality. I tried a cheaper camera and returned it. A lot of people complain about the lack of functionality on the Viofo app but I bought it for the quality of the camera, not the app. Installed behind the right side of the rearview mirror, the camera is easily hidden from the driver's view (see pics). If you want to use the parking mode on the camera, you will need to purchase the hard wire install kit. I recommend it. The installation is very straight forward. I have the two-channel camera running front and rear. For a rideshare driver, you can mount the rear camera on the windshield and use it as an internal camera. If you purchase the three-channel and run all three channels together, you lose the 4k resolution. Overall, I am EXTREMELY happy with this purchase. I would recommend it to anyone looking for a dashcam. There are cheaper options available but they don't come close to matching the quality of the Viofo A139 Pro. It's worth the money. ... show more

    • Just getting familiar with it.
At times, it will disconnect and/or disable the Wi-Fi signal but it doesn't interfere with traffic recording. I disabled the parking mode as I can't risk a dead battery. Video image is OK but I'm not comparing it to any other dashcam. This is my first one and I chose it because the Sony Starvis chip is highly rated and not widely available. ... show more

    • So far so good.
I had an old dashcam (was $99 on Amazon, back in 2019), but realized that it was not working over few months. I felt that I need a better one - at least more reliable, and got this one. Installation was not difficult. It's just same as other dashcams - I used default cables. One downside is that this one does not have a built-in LCD, so you need a phone with an app on it to control the dashcam. But again, it's better than struggling with poorly designed UI/buttons on the dashcam. App looks good, convenient and works fine. If you are familiar with IoT devices over WiFi, this thing is a piece of cake. Haven't had a chance to investigate the recorded video under different environment, but I hope I do not need to do such thing. ... show more

    • Disaster. Parking mode is BAD! Stopped working in a week!
1. First thing you need to know if you plan to use it in a parking mode - it eats the life out of your battery like nothing else I've ever seen. Even if used with regular USB that stays on after ignition is off - beware it can drain your battery - will need to unplug every time. It explains overheating issues the others reported. 2.Need to buy a specific SD-card - won't work out of the box (because they don't give you any). And not just ANY SD card - there are only few specific brands it will work with (check their website). You also need to buy hardwiring harness (18$+70$ for the specific SD) - really should be provided with the kit. 3. I additionally bought the video saving button for the camera (saves the video footage on demand). In case of an accident - the only footage recorded will be everything after the accident. It really feels like a bug, course it makes no sense. Normally 10-15 sec before should be also saved. 4. MY ISSUE! Video quality is great, but my camera stopped working a few days after I hardwired it - no more GPS, WiFi does not connect to the phone, recording is on/off all the time. Tried different memory cards, disconnected hard-wiring harness, connected to regular USB, tried re-set button, checked the voltage on USB and hard-wired harness - everything is fine, but still no recording. It's particularly frustrating cause I did waste my weekend on hard-wring and proper installation and now I need to take it all apart. 5. The customer service was quick to respond and commented on every issue, but I made up my mind to return it. It feels cheap to the touch, the 3M Tape was dried out (but they provide a spare one in the kit), the camera rotates freely 360 degrees (moderate offroading in my Jeep affects the lens position/orientation). ... show more

    • Good quality
Excellent video quality, front and rear, day and night. The size is ok, not too big to fit on the windshield. The installation requires some professional help in order to get the best outcome. It’s easy to use, and works great.

Bought the dashcam for my wife's car as she drives over 60 miles per day (one-way) to and from her work. There's lots of driving skill "opportunities" on the interstate highways so having an "eye-witness" can be a real benefit if you're unlucky enough to need one. The front camera produces one of the best images on the market today and the rear camera is adequate for most situations. Both cameras were easy to install. I especially appreciate the smaller diameter cable for the rear camera - it was much easier than other, thicker cables, when running along the headliner and through the conduit at the rear of my wife's Mazda CX5. There are a lot of great videos online (Vortex Radar and Blackboxmycar) that give deep dives into the specs and pros/cons versus other units. For me the picture quality was the deciding factor. If I had wanted a stronger parking mode or cloud features I may have chosen the Thinkware 3000 or other unit (Parking mode is OK with the VIOFO but is not as strong as the Thinkware. The VIOFO does not offer cloud capabilities at this time.) Great unit for the price and meets my needs. ... show more
