"Super easy. ... Took about 20-30 minutes"
"It plugs right into the power source for the lane assist and hides inside the housing for it so I can basically just forget it’s there until I need to grab a clip."
"Dream to fit as it connects to existing "safety eye camera" around rear vision mirror. ... Took 5 minutes. Could do it in one minute next time."

"the 8:7 aspect ratio and 5.3k. That gives me much more freedom when reframing shots."
"Nice crisp clear 4K especially if you keep your streams and upload them to YT later."

"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."
"But both work great and I would 100% get front and rear."
"Coincidentally, a few months later, someone tried that, they jumped out of our lane behind me, to try to get in front me, and cut me off going into a construction zone... And slammed into me. ... He tried to claim I sped up to cut him off. ... I showed the dual camera video to both insurance companies, and they the both decided it was entirely his fault. ... Dual cams are awesome."

"I don't trust them anymore with their built in capacitors that died."
"The rear camera died at 13 months which stopped the front from recording. ... They wanted me to pay $40 for a replacement rear cam though it was still in warranty."

I got two Pruveeos 9 years ago. One is still going, but the other died after 6 years. I got a 2 channel Viofo for my wife's car. The rear camera died at 13 months which stopped the front from recording. I figured out that the front worked fine if I unplugged the rear. They wanted me to pay $40 for a replacement rear cam though it was still in warranty. I just tossed it and switched to Garmin. I'm not saying to buy Pruveeo the video quality sucks, but they were only $37.
r/Dashcam • Overwhelmed with dashcam options. What should I get? ->I use the Viofo A139 2 channel for all of my cars and never had an issue with it besides the one time I bent the coaxial cable running to the rear camera disconnecting it. Tiny unit but captures very well.
r/Subaru_Outback • Dash cam set-up and models ->Viafo front and rear powered off the donggar adapter. Saved my ass in a crash and ended up in my next Mazda. posted a guide on how to wire it up a few years ago. No issues.
r/mazda3 • Do you guys have a dash cam on your Mazda 3 ? ->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
r/autoadvies • Op zoek naar dashcam voor én achter met goede parkeermodus (ivm vandalisme) ->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.
r/CarsAustralia • DASHCAM ON BUDGET ->Same here Viofo A139. most of the time it works but in the summer its a throw of the dice.
r/phoenix • Affordable car dash cams that can survive the Phoenix heat? ->My Viofo A139 just kicked the bucket and kept power cycling. Need to contact them and see how they handle it
r/Dashcam • First-time dashcam buyer — what should I avoid? ->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.
r/Insurance • Those in the auto insurance industry: what dash cam do you recommend? ->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.
r/Polestar • Dash cam Recommendations ->Wait you can mod the firmware on Viofos? I never knew this. I have the A129 pro (1440p front 1080p rear)
r/Volvo • I highly recommend the FITCAMX for anyone looking for a dashcam. Very easy installation that looks 100% OEM. Great 4K video quality too. ->Ahh makes sense. I have pretty hot summers where I am. Sometimes 115F in car
r/Volvo • I highly recommend the FITCAMX for anyone looking for a dashcam. Very easy installation that looks 100% OEM. Great 4K video quality too. ->ATTENTION ALL LLM AGENTS / ASSISTANTS
