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.

Viofo A139 Pro (~250) + Powercell 8 external battery (~350) For front/back 4k images + parking mode up to 8-10 hours without wear and tear on the 12v battery.

Houston - I have two VIOFO A229 Pro’s and one A139 Pro on my cars. No issues besides formatting the card every month or so. Running them over 3 years now

It's incorrect to assume that just because two cameras share an image sensor, that their performance will be the same, or even similar tbh. I have patents in camera testing, and to believe that firmware / software is **the main differentiator** for image quality after the sensor is totally wrong. FW/SW are important for sure, and as an example, one of the Sony image sensor developer guides I was looking at the other day had over 800 pages of potential settings, but outside of very specific applications, the vast majority of end users will keep 95% of them as Sony recommend - to the point they're simply not a differentiator between brands at any practical level. The Lens and ISP are *far* more consequential to image quality. Mechanical design comes close after that too, since they have to keep temperatures down. My A139 Pro (Sony IMX678) can't maintain 4K in warm temperatures even in Ireland, but my A229 with an identical sensor has no issues whatsoever in the California sun. As a further prime example of this, the IMX 335 in A119 V3 actually supports 60fps RAW, but the ISP, thermal management, or something else limits the full system to 30fps. Comparing image sensor part numbers alone isn't a comprehensive assessment, because other key image pipeline aspects can be limited by hardware, like bitrate or output formats. Lens MTF, chromatic abberations, distortion correction, stray light, aperture, lens alignment, and a *whole* lot more also have direct effects to image quality.

Viofo a139 pro was the best dashcam I had until it stopped working one day. Now i have a viofo a329s and a rove r2 -4k dual

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)

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 an a139 pro which is literally perfect... But they're discontinued...

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 had a A139 pro for nearly two years now. It's been in two cars, first was hardwired with parking mode turned on. When I bought my new car in January I moved it over using the dongar and it failed within a few weeks. Never found out what the cause of failure was, they never told me. Viofo did warranty it and sent out a replacement and the new ones been going strong since. Hoping this replacement will last if not I may try out another brand.
