it's more than worth it, even just for peace of mind.

I currently have a [VIOFO A129 plus duo](https://viofo.com/dash-cam/197-a129-plus-duo-dual-channel-dash-cam-front-2k-1440p-rear-1080p-5ghz-wi-fi-gps-dash-camera.html) that is wired for parking mode.

I have Viofo A129 Plus Duo and while I’m very happy with the recording quality, the app simply does not work and the OEM hardwire harness kit (which is the only brand that works with this camera) has horrible quality and will die on you within a year. For those reasons I’d recommend staying away from viofo.

I'm dissatisfied with the A129 Plus Duo I got

It was well worth the money and time to install.

The latest firmware does not allow buffered parking mode on these cameras

Out of the box it was constantly dropping the rear connection, I spent a lot of time emailing support (who were helpful) but eventually solved it myself as a shoddy firmware.

my unit allowed me to record 2K 60FPS + FHD 30FPS simultaneously

I think the main advantages of the dashcam is the low bitrate recording. It is constantly recording during parking mode so you do not miss any incidents at all

I have the A129plus Duo installed in two cars. One had some minor issues early on but has worked without issue for several months now using a non-High Endurance SD card from either Samsung or San Disk.

Took a few drives in both daytime and last night and was very happy with the results

Day time footage is awesome 👏 both front and rear. But strangely for night time footage I like the rear cam better than the front cam. Front one is bright but too much grainy

Viofo a129 plus duo is the one I have and works well. But you NEED to update the rear camera firmware to make it work properly.

I’ve had it for about a year and have had no issues with it at all.

My Viofo camera is fried and now longer works. The GPS module is 100% broken and the side power inlet is in and out with being reliable.

If you do get this and decide to hardwire it to the car, get the Rexing hardwire kit - the viofo ones kept malfunctioning on me. Had to replace them twice within a year or so before getting the Rexing kit, then the issues stopped.

Currently have a Viofo A129 Plus Duo and can't speak highly enough of it.

I park outside too, and I have the Viofo A129 Plus Duo. I use parking mode, and it works well, but I just want to warn you that you’ll get a ton of recordings through the night.

The first time it did the double beep, start and stop recording for 5 seconds on a loop

I got the Viofo A129 Plus Duo on Amazon, and it's good. Its a 2K front and 1080p back system and I have it run in parking mode when the car is not running.

If you are going to go with viofo then stay away from the A129plus duo, it's a shit cam and gave me nothing but issues.

Reddit— neutral

I think it's not worth it to have a rear dash cam; driving at night means you can't make out shit on the recording, and these cameras are already rather garbage to begin with.

I have the Viofo A129 Plus duo and its been great.

I have tried 2 new VIOFO A129 Plus Duo a few years ago and worked with the dealer for 1 month trying many things from firmware change to sd card change and wiring and ... , the continuous recording would work for a few hours and then it will stop completely.
