Vantrue N4 vs Viofo A129 Pro Duo

There are no other dash cams on the market that I know of right now that have three dash cams. So this one specifically, it's got a forward-facing cam...

When installing take a black sharpie or some kind of marker and under the red plastic that you peel off to stick the cameras on the windshields you will see a white strip, color this black first, lest you have a white line you will clearly see through your window. This strip is there to make peeling off the red plastic easy its not sticky where its white. You can guess how I know this. Next tip you will need to buy more stuff or will want to

However, the parking mode does work better on the newer unit, though probably not well enough to prove it if a stalker is driving past my house 10 times a day. And I noticed something about the night vision in the new unit -- it seems to work via infrared, because you could see a part of my bra's outline in one of the interior videos I reviewed. I was wearing a dark blue shirt at the time with a printed image on it that made it impossible to see my bra under regular light. However with this dash cam's night vision, you could see the straps and upper part of the bra well enough to know it was there

Parking mode is a bit of a mystery to me, though. I've set it up to record in timelapse, but it just keeps on recording in regular mode. Maybe that's just me doing something wrong. Also, the image quality is pretty good on the front camera, but not $250 good

I run my dashcam on the highest resolution on both cameras, and the highest bitrate on both cameras, sectioned off into 1 minute clips, both front in rear. The dashcam sections these off into numbers, for example: "20200818_101037R". These break down into the following: 2020 - year, 08 - month. 18 - day, _ - separates the day with the exact time, 10- military hours, 10 - 10 mins, 37 - 37 seconds into the minute, R/F - Rear camera and Front camera respectively

But for something like this to just quickly toss in the car, it was convenient, good video quality, and did a nice job. And so I think overall, it's a...

The only condition where you will see quality degradation is when the sun is directly reaching the lens but even in that condition the A129 Pro Duos i...

Due to a big console for my rear view mirror and sensors on the windshield, I had to mount the N4 on the passenger side instead of the driver’s side like my N2 Pro. The reason was partly the larger size of the camera, but mostly because the suction cup mount caused the N4 to hang lower than I would like. The wire connector also points up rather than to the side like the N2 Pro, so that lowered the mount another 1/2”. Ideally, I would like a smaller fixed adhesive mount with side wire connector instead of the suction cup mount

When trying to keep the dash cam up and out of my view, the only good spot I could mount the camera also happened to be right behind my rear view mirror. While this doesn't completely limit my ability to adjust the rear view mirror, if the unit were 1-2mm thinner then it would be a non-issue. Small complaint for an otherwise great dash cam for the price.
