VIOFO - A139 Pro 1CH

I use Viofo (specifically the A139 Pro but there are other options) and it's great. I have mine plugged into an external battery pack because I don't want to hardwire it. There's actually tons of good options now, dashcam technology has come a long way in recent years and there are some great quality cameras. There's also r/Dashcam for sample videos.

I’ve had the VIOFO 139 Pro front and rear for a couple of years now and it’s been flawless. Easy to connect to it with the phone app and view or download clips. Has parking mode if you hardwire it with movement sensor and G-sensor plus time lapse recording.

Most dashcam enthusiasts recommend Viofo and Thinkware with the STARVIS2 sensor for the dash cam of choice. You may have to look into BlackVue for push notifications, as they have some cloud services. I personally run a Viofo A139 Pro hardwired into a Powercell 8 external battery that is hardwired into driver side fusebox for parking mode. The setup is about $500-600.

Viofo or Thinkware, and any dashcam equipped with the Starvis2 sensor, are the go-to for dash cam enthusiasts when it comes to picture quality and license plate reading. The most optimal parking mode setup, but most pricey, is a 2/3ch dash cam hardwired into an external LiFePo4 battery that is then hardwired to driver/passenger fuse box. This setup will provide parking mode and reduce the wear and tear on your 12v battery. If parking mode isn't something you need, you can just to the 12v accessory socket for normal driving dash cam use. I used Viofo A139 Pro and have installed Viofo A229 Pro on family's car.

Bear in mind the A119 would never be able to capture the plate if it’s not day time+ stationary, if it’s a hit and run guaranteed would not be captured, I went through thinkware x1000, A139 Pro( actually gd video quality no problem capturing plates on speed, but the 139 has a known cable issue that the rear camera might disconnect occasionally, switched to the newest a329s, cable issue is gone)

A229 Pro is the most popular one I sell. If we’re talking sleek though, my vote goes to the A139 Pro. It doesn’t have a screen so it’s a much more elegant package. All Viofo dash cams purchased through me come with a free plug and play harness so you don’t have to wire anything yourself. https://hachielectronics.com/products/viofo-dash-cams-in-stock-models If you decide to go with something other than Viofo, I can also make the PnP harnesses for other dash cams. I have options for Garmin and Vantrue on the site, but you can also select the other option and specify your dash cam model. https://hachielectronics.com/products/2022-gr86-brz-pnp-dashcam-hardwire-harness

Another vote for Viofo - but the A139 Pro, and definitely get both front and rear. A cyclist hit me (yes, they literally cycled into my stationary, parked car), and it paid for itself in one insurance claim. I liked the fact it didn’t have a screen, which makes it much smaller and hide behind my rear vision mirror. I don’t even see it when driving. Mine is hardwired into my car battery, so it records when I’m parked and away from my car too, so I’m never worried about someone doing a hit and run when I’m parked on some crappy narrow Auckland street.

i have a viofo a139 pro. it does not have a factory look like the fitcamx. however, i want the best resolution camera back there, and the dual ones out there, including fitcamx, all have 1080p res. the viofo is 4k, and it has a polarizing filter. i just used the acc port in the left side, and kinda stuffed the wire into the trim. i did pull the upper trim piece and used my dremel to remove some trim. the last 5 cars have all had front and rear cameras, and at least 3 times we got punted in the rear, not once in the front. one time some dumbass ran in to us at the wendys drive thru. who does that? another was when we were stopped at a red lite.

Viofo A139 Pro with front, rear, and interior cams. I also run the hardwire kit and keep my car monitored when it's parked outside my workplace.

I got Viofo 139 pro The sony chip in it is really good at night time. The image of plate number and other details are so good.

Not too familiar with the new models but I’ve had a VIOFO a139 pro (I believe this model is discontinued) for almost 2 years now and it’s been near perfect. It did fail on me a week before the warranty expired but they handled it well and sent me out a new one no questions asked once they confirmed no troubleshooting could solve it.

Viofo A139 Pro, have had this particular unit installed in two cars now and its been perfect. Plus Viofo support was decently good with getting me a replacement when it died two weeks before warranty expired. Viofo makes better models but I wanted one without a screen, though I may upgrade to a nicer one at some point. I know around me alot of car audio shops also do dashcams, however it is very simple to install and hide the wires; if you want to try to save some money. https://preview.redd.it/vexmsj0eqwff1.png?width=1138&format=png&auto=webp&s=14ed454abd0982f45edecd6268932836f96624e8

I have a A139 pro in mine that i installed afew months ago when I got my CX50, tapped into the dimming mirror for power using that T harness you can get online and have had no issues with it. I know people with other Mazda's that have had their dashcams hardwired with no issues as well.

I have an A139 pro in my other car, but worry that it will block some view in the ev6 - do you have one mounted without blocking any view?

My Viofo A139 pro does not work on any of the cars USB-C connections tried many different cables none work, my phone charged fine from all those USB-C connections with all the tried cables. When I measure the power when my phone is connected it can only pull 7 Watt. Looking online it seems that a lot of people complain about this and skoda changed the power source in the MK4 facelift to produce more wattage. So I'm actually now looking to see if I can buy the upgrade USB-C people from the facelift model and replace it (if it fits that is).

I really like the look of the Viofo A139 Pro. 4k, excellent image quality, dual camera. It records in an SD card, in the camera. You connect to its built in WiFi to retrieve the footage. It does not need WiFi or cell coverage to function

I own both a Kia EV6 and an Ioniq 5. I purchased a Fitcamx (front and rear) for my Ioniq 5, but I encountered an issue with the adapter that connects to the rearview mirror—it never turned off. The company quickly sent me a replacement cable, which resolved the problem. Aside from that, the installation was very easy, and the picture quality was decent during the day. However, nighttime performance was not as good. For my EV6, I decided to go with the Viofo A139 Pro, and the picture quality is significantly better for both daytime and nighttime. The installation was also fairly straightforward since you can get an adapter to tap into the rearview mirror for power. However, I opted to use an external battery to enable parking mode. In conclusion, both cameras serve different purposes. If you prefer an OEM look and are okay with slightly lower image quality, the Fitcamx is a solid choice. However, if you want a better app experience and superior video quality, I recommend going with Viofo or BlackVue.

\+1 to this as well, why I got the Viofo A139. At the time one of the first with the Starvis 2, but now there are a few.

I have Viofo A139 pro cameras. 2 are in a cars with front tint, one in a car without front protection. All are working well. These do not have caps but I have aux. battery backup (BlackBoxMyCar) for when the car is off and the cameras are in parking mode.

I’m in Alberta. I have the VIOFO A139 Pro with front and rear cameras and it has worked fine in the cold weather.

The VIOFO I bought is probably not current anymore. I think any of the VIOFO models are pretty good. They aren’t cheap but I’ve had the cheap ones before and was always disappointed.

VIOFO 139 pro. It’s great. I have interior as well so they can’t say I was doing something I wasn’t.

I have the VIOFO A139 PRO, no complaints on it at all, Great camera overall. I also have it hardwired for parking mode when I’m away. Has a regulator you can set for voltage cutoff so it doesn’t drain battery, however use some fuse taps, in the fuse box under the steering wheel. I did red wire to 20A Socket, Yellow Wire went to 10A Meter/Battery. Easy set up, you can find a decent amount of videos explaining online as well.

Another vote for Viofo. Installed the Viofo A139 Pro front and back in my Cayman and can vouch for the image quality. They were the only dashcam at the time that had the Starvis 2 image sensor (which I’m familiar with from working with security cameras), so the image quality at night is also bright and crisp without either lots of night time motion blur or dingy image you would associate with lots of other cameras. I used fuse taps to the footwell fusebox so it’s 100% reversible if I wanted to change/remove it. I need another dash cam for my daily so I’m going to pick another Viofo up when I see them on sale.

I had a similar issue with the A139 Pro. At first It seemed like normal overheating, having the AC on all the time helped for a while. After 6 months it began rebooting non stop even in cold mornings. Updated firmware, tested with and without gps mount. Using the cigarrete charger adapter worked fine, so I thought it was a power issue. Then I noticed the power cable was hot, not burning hot but still. I Changed the cable with a different one with fast charge and it has been rock solid for 2 weeks even in hot days. So I'd say check your wiring, if the SD card is fine and the camera itself does not get too hot, it might be an issue with wiring and /or power.

Really liking our viofo A139. Really clear image!

AZDome M300S 2 channel heb ik op ali voor een €65 gekocht en het werkt uitstekend. Beeld kwaliteit is ook heel goed. Dit komende van een Blackvue 750s. In mijn ander voertuig heb ik een VIOFO A139 en dat is ook een goede cam, albeit een pak duurder

It was watching DCOA videos and paying attention to the brand watermarks what made me pick my Viofo A139. Image quality is great day and night, picture is clear and sharp without feeling over sharpened. Hardwiring was pretty simple too. Fantastic insurance, worth every cent.

Same here Viofo A139. most of the time it works but in the summer its a throw of the dice.

My Viofo A139 just kicked the bucket and kept power cycling. Need to contact them and see how they handle it

I've had Viofo A139's in my cars for 4 years now, they still work flawlessly even after enduring a couple of Texas summers parked outside. Great build quality on them. 

They also have the A139 model, same starvis 2 sensor but it doesn't come with a screen so it's even less of a footprint. Can't say I've ever used my dashcams screen for much. I generally turn on the wifi and check from my phone app.

Iv had viofo a229 last years no problem but my viofo a139 exploded last summer and i get sent a replacement

Just bought VIOFO front and rear for my truck.

I have a Viofo front and rea rone. Check out the LinusTechTips video on dashcams - they all use the same sensors

I had a Viofo front dashcam on my 2023 SEL which I loved. Got a 2025 Limited, but there were no kit for installing a Viofo. Finally installed the FitcamX, which took about 10 minutes. It works surprisingly good, but there's not very much to the hardware. Would have rather spent a little more to get a Viofo, but having the FitcamX is better than having no camera.

Most important thing when it comes to dashcams is image quality, particularly at night. The fitcam sucks Get a viofo or some other high quality, true 4k hdr cam instead. You can get a mirror connector adapter for power.

Second the VIOFO pro suggestion. I bought off amazon and paid Best Buy to install

Viofo is what I run, you basically want a camera with the Starvis2 sensor and ideally the 4k version.

Very happy with my Viofo excellent low light 4k

Viofo 4k, love them and keep upgrading on all 3 cars in the fam

Viofo 4K, with or without hardwire kit.

There's also viofo 4k If you run from usb or lighter socket then there isn't a issue. When you hardwire it for parking mode there is a hardwire kit that'll automatically cut off power if the battery goes below a set voltage In any case these cameras should not take more than a few hundred milliamps when operational. 5amp can run like 4 of these camera

Screw it looking oe. What you really want is a good camera. Viofo makes some of the better ones WITH a rear camera as well. After doing lots of research, lots of them use garbage cameras but the better ones use Sony. Specifically the Song Starvis. The Starvis 2 just recently came out and viofo made a new one with the 2. Good cam, doesn't look ugly. Supports parking recording and collision detection. [viofo Amazon ](https://a.co/d/izrOa1d)

Also a fan of Viofo. Been working great since I installed it just over a year ago. I got it because of the Starvis 2 sensor which gives improved clarity in the dark. If anyone is driving at night I highly recommend any dashcam with a Starvis 2 sensor.

I've had good luck with the viofo dash cams over the years. Some of the more expensive viofos have the Starvis 2 sensor, which does get a slightly better image (which might help if you are reading a license plate). Buy a really good high-endurance SD card, no matter what you buy And if you are ever in a collision, read the plate out loud so the mic can pick it up. Just in case the camera doesn't quite pick it up.

VIOFO. Whatever brand get one utilizing Starvis 2 sensor and that has HDR. Seen alot of recommendations for Dongar adapter for clean install into mirror.

Just when I think I have a good answer, someone comes up with a better answer. The hardwire kit looks great, definitely going to get that for my viofo. For others that are shopping, the starvis 2 sensor this has is great. I have both the older and newer viofo units, and the starvis 2 definitely makes a difference compared to the previous gen.

Looked into the Fitcam and VIOFO. The sample footage Fitcam support sent wasn't promising, so I went with the newer VIOFO using Starvis 2 image sensors. Doesn't really distract me but I do occasionally get questions from passengers. Also feel like having an obvious dashcam as a deterrent for reverse-into-you insurance scammers could be a plus. Overall happy, do wish it could do 1440p60+HDR in both front and back simultaneously though.

VIOFO, and make sure it says "STARVIS 2" sensor. Not "STARVIS", but "STARVIS 2". Also get the VIOFO branded Industrial Grade SD Card. VIOFO Industrial and Sandisk MAX Endurance are the only two SD cards recommended by VIOFO. Other cards have potential of file corruption after extended use.

Watch some of those Dashcams compilations on YouTube to get an idea between cheap vs good, you'll notice the difference in quality between clips. It comes down to sensor quality and key features. IMO Viofo are excellent for the price. Sony Starvis 2 sensor, parking mode, wifi and app.... actually these are the only functions I really use.

Yes, although I would go for any Viofo with the Sony Starvis sensor.

Vantrue or VIOFO. They both use the Sony Starvis image sensor and have great quality. The cameras are pretty set and forget if you opt for the hardwire kit. It will turn on and off with the car and start recording as soon as it starts up. The included power adapter does the same thing if your power port in your car turns off with the ignition.

70Mai is good - I've one in the CX5, front and rear cameras - and bought direct from AliExpress - retailers here sell the same thing, just for more. Do the math. Also the Viofo seem to be getting traction well - pick anything with the Sony Starvis sensor really - they're good in day and great at night.

Yes, but I’d recommend a dashcam with higher resolution than 1080p. Preferably 2.5K* or 4K. I like Viofo.

I have a couple viofo A-series, they're awesome. Wolfbox is also getting popular.

The best cameras are the Viofos but the Fitcam is the easiest to install cleanly and looks OEM so it really depends on what you're after.

Viofo from hachielectronics. It plugs from my fake engine noise so it doesn't have to take up usb space nor have to do any fuse voodoo.

For install, look up a video on how to install one and it tells you which fuse to tap. You’ll have to drill a hole on the silver frame of the dashboard to get a ground but overall it’s not hard to install. I recommend Vioflo or Nextbase.

GKU D700 - around $122 on Amazon after coupon. Have 3 of these in our household and they’ve been flawless (installed with the hardwire kit for an extra $25ish). App is great, decent size touchscreen, good quality front and rear video and capacitor based I believe. Had Viofos in the past which didn’t last more than 1-2 years, so thought I’d give these a try.

I've owned several Viofos and I don't trust them anymore with their built in capacitors that died. I now have 70mai brand. Have the model A800S

I've owned a bunch of Viofos but have switched to 70mai for the Ioniq 5. But anyways, you should mount it on the plastic part with just the lens peeking enough to view the street. Or put it on the right side of the plastic housing. It's annoying having the dashcam visible in your eyeline.

I've ran several viofos with no problems. Currently run a A119 V3. No problem easy install. Been running them for years. Usually if something is wrong, its the sd card.

Try watching Dashcmas Australia, take of the the crappy ones and the good footages. Most of the good ones I see consistently are Viofos.
