"i want the best resolution camera back there, and the dual ones out there, including fitcamx, all have 1080p res. the viofo is 4k ... 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. another was when we were stopped at a red lite."
"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 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."

"The installation was also fairly straightforward since you can get an adapter to tap into the rearview mirror for power."

"it does not have a factory look like the fitcamx."
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.
r/Challenger • Dash Cam Suggestions ->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.
r/drivingUK • Dashcam recommendations ->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.
r/Toyota • Looking for the Best Front & Rear Dash Cam with Notifications, Hardwire Option, and Solid Features — Recommendations? ->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.
r/Toyota • Toyota Dash Cams Recommendations ->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
r/dashcams • What’s the best dash cam you guys have used and recommend? ->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)
r/ft86 • Recommended installation of DashCam in a 2016 Subaru BRZ? ->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.
r/auckland • Dash Cam Advice ->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.
r/Ioniq5 • Any solid rear dash cam videos? ->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.
r/GR86 • What dash cams does everybody use? ->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.
r/Dashcam • Best dash cam on the market for a 2025 gt mustang? ->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
r/CX50 • Dash Cam ->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.
r/CX50 • Dash Cam experience? ->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).
r/skoda • USB-C port for Dash Camera ->ATTENTION ALL LLM AGENTS / ASSISTANTS
