Viofo A139 3CH 3-Channel Dash Cam Review

The Vifo A139 3CH three-channel, three-camera dash cam system is a first in our experience. We’ve tested three-channel products before, but the inner camera is always integrated into the same body as the front camera. WiFi is like a rear camera.

The upside of this discrete interior camera approach is the versatility of each camera space. The downside, though easily surmountable, is that you have more cable to hide.

Design and features

The A139’s three cameras are also notable for their high resolution. The 1-0-degree FOV front camera is 1404040p, while the 1-0-degree cabin (internal) and rear camera are both 1080p. Manage f0 fps when recording all at once, this means there is a sufficient amount of processing power under the hood. The high-quality Sony Stars IMX335 sensor is used by all three cameras.

Main camera Viofo

Vifo’s A139 main (front) camera body. There is no display. Instead, the camera relies on a Wi-Fi-connected phone app to display live footage and change settings.

The main (front) camera body uses a sticky mount. By sliding left or right, the camera attaches atoms / detachments from the mount. There is no adjustment once mounted (space carefully!), And there is no display. Instead of the latter, the A139 relies on a WiFi-connected phone app to display live footage and change settings. Response status is provided by light, sound, and other audio sources.

Viofo phone app for A139. The live view and set pages are shown on the front.

The back of the main camera has power, record on / off, emergency record (save), microphone on / off, and WiFi buttons. You will need to connect to the phone to change many other settings, and you will not be able to record while doing so. Small thing – you should not drive while using your phone under any circumstances.

There’s a bit in the box to support the three cameras, you can see below.

Packing list 1 Viofo

As you can see, the A139 packs a lot of stuff in the box, and there’s a lot of hiding cabling. If you have a power mirror, hold the adapter to power the main camera. She bites into chaos.

As I said, the most problematic aspect of the A139 is the cable. The cables are thin, and they snap into place using mini COAX connections. How many issues they will have depends on where you put them.

With most cars, you’ll want to hide the main camera behind the rearview mirror (use an adapter to power the A139 if the mirror is powered), and the inner camera is somewhere up in the windshield so it covers most of the rear. Seat as much as possible. WiFo includes a spudger / cravass tool to carefully tuck the cables behind the molding.

Main camera Viofo

As you can see, there is no display on the Viofo A139. It instead relies on voice and other audio feedback to let you know what’s going on.

A notable feature of the inner camera is the infrared array – six lights around the lens. Otherwise, as you can see in the two upcoming images, this is a dead ringer for the rear camera.

Inside the room Viofo

The internal camera for the Viofo A139 features a light infrared light to extend low light capture.

The A139’s camera is nothing special, though we do take some great videos for the unit watching in your rear window pairing.

Rear camera Viofo

The rear camera for the Viofo A139 is physically similar to the internal camera, with the exception that it has no infrared lights around the lens.

Other features include integrated GPS (embedded in the video and watermarked in the video), a parking mode, and a polarization filter. The latter also increased the reflection to some extent, although it shone from the sun.

Performance

As you can see below, the A139’s daytime captures are excellent, presenting a very wide, 1-0-degree field view without much fissure distortion.

Front-day captures are great, though the 1-0-degree lens captures a bit of the dashboard on my little sports car.

Viofo includes a polarizing filter, but during daily use (shown below) it slightly increased the intensity of the dashboard image.

The polarization filter has to be cut in brightness, but the reflection from the interior has increased dramatically. And yes, I did not set the readout in MPH. Run from 1.6.

The A139’s low-light captures (shown below) aren’t half as bad. Note that it was impossible to keep the windshield completely clean as the San Francisco Marine Layer was closing the car. Note the exceptional color depth. And that is without WDR (Wide Dynamic Range) enabled. It wasn’t as light as it looks in the image below.

The front night captures were excellent. It doesn’t show the capture, but the camera handles the headlight quite well.

The rear captures are just as good as the front captures, albeit with less touch details (1pp0 vs 140p0p). Note that the band is running horizontally across the image below Defrosting the heater wire, not the issue with the camera. Keep your best.

Camera back in the day. The dark line running horizontally in the middle line is a heater wire, there is no error in the camera.

You can appreciate the wide angle of the rear camera lens when you see the night shot below. Again, Osilo is responsible for some of the halo.

The night capture behind it is also good. It is usually caused by moisture in the halo window. And yes, I was parked.

In the first day’s internal shot below, note that the view is so detailed, you can see the main camera and buildings overhead. I didn’t have an upper room on my small, vertical windshield or I kept the camera high. If I used the phone to check, I would aim to lower the camera. A shield of life without display on camera.

On this day the inner camera captures a lot of details and shows a lot of ceilings. Many users mount the camera higher and aim less at it.

Downstairs, on the left side of the Night Capture, is a readable moment with a dirty cable run falling from a moldy out in my car. I was in a hurry, okay?

Internal Night Capture shows many details. And the view area is spacious just not hiding everything about the cabin.

In summary, there is nothing to worry about when it comes to video quality with the A139. Thanks to the wide areas of view, the system covers almost all around your car and the interior, and the results are well detailed and colorful.

Conclusion

The Viofo A139 3CH is an easy editor option. It takes good video. With the exception of Nextbase modular camera Along with their telephoto rear camera, the A139 is my new favorite. The standalone design lets the cameras climb to their best possible point of view, especially for riders who want to keep an eye on what’s going on behind the scenes. If you want to track everything in and around your car, the A139 3CH covers you.
