Viofo A129 Duo, current would be the plus version I think.
I've had the A119S and A129 Duo Plus both are rock solid.
Had a Viofo for around 4 years. They're excellent quality, unbeatable value IMO.
This one: https://www.viofo.com/products/a129-plus-duo-dual-channel-dash-cam-front-2k-1440p-rear-1080p-with-wi-fi-gps-dash-camera Although they may have newer ones that I'd go for now- I haven't needed to look since buying this one.
Viofo A129 Plus Duo is a great value 2 camera setup.
I’ve got VIOFO A129 Plus Duo in both my cars. I would strongly recommend getting a hardwire kit as a lot of car have always on power to the 12V socket and you may end up with unwanted battery drain.
I've always been a fan of the Viofo A129 Plus Duo—it's the perfect balance of video quality and value. The dual-channel setup offers peace of mind both in front and rear coverage, which is super important in today’s driving conditions. One dream feature I’d love to see is AI-powered incident detection that can automatically save and categorize events based on severity. Also, love how Viofo consistently listens to user feedback—keep that up! It makes a huge difference knowing the brand actually cares about real-world usage.
VIOFO a129 plus duo. Front and back. Hardwired with a fuse tap
Mine died after about two years, turns out it was the usb port that died. I switched to the other and it has continued to work since then.
Viafo uses super capacitors instead of a traditional battery, it’s why they last a bit better in our climate. If you’re patient and set up a price watch on Amazon using something like [camelcamelcamel](https://au.camelcamelcamel.com/product/B08577PXK5?context=search), you can sometimes get lucky and get a price nearer to 200. Also recommended is o get the polarising lens to eliminate windscreen reflection.
Depending on the dash cam some will eat power for breakfast. To know how long you can have parking mode for will depend on that, the condition of your battery and how many events get triggered. I tested the Thinkeate U3000, BlackVue DR770X Box, VIOFO A129 Plus Duo, and Akeeyo EYES AI dash cams to show how much power is used by each in parking mode. Watch for more info: https://youtu.be/52nfmtyEEQ8 I also am trying to use a solar panel to potentially have unlimited parking mode. Find out more about the solar dash cam project here: https://youtu.be/BI-fhD5w0m8
How long you get for parking mode will depend on several things including how much power your dash cam uses in parking mode, the state of charge of your car battery, the condition of your car battery and the amount of motion in your parking spot. Currently, the Thinkware U3000 and U3000 Pro have the longest parking mode when set to RADAR. I've gotten past 8 days but again depends on those factors I mentioned above. If I were to use a dash cam battery pack I could probably extend it to past 21 days. These are expensive dash cams so budget will also play a factor. It's possible a different dash cam used with a dash cam battery pack could cost less and last more than what you need it for. Note too that dash cam parking mode differ between brands and makes so you would want to know how it really works for a specific dash cam. A lot of cheap dash cams implement parking mode not too great or use too much power or have a long wake-up time. This matters because if it takes a long time to wake-up you will miss recording some or all the action. Here is my comparison video on parking modes and power usage of some common dash cams: [U3000 vs VIOFO, BlackVue, Akeeyo](https://youtu.be/52nfmtyEEQ8) [My full Review of U3000 Pro](https://youtu.be/6PxwpG2-ZII) [My full Review of 70mai 4K T800](https://youtu.be/G88zYI3J5YE) [My full Review of VIOFO a129 Plus Duo](https://youtu.be/9YQGChfUGIY)
To add... Just because a dash cam says it has motion detection in the specs doesn't mean it does it well. For example, the VIOFO A129 Plus Duo doesn't record an impact if motion detection doesn't happen first. I think that is not the best way to implement it. It should always record impacts and motion detections independently. I show this in the VIOFO review.
I use a VIOFO A129 Plus Duo. It is a front and rear camera. Install was not too bad having done a few dash cam installs before. The front was stupidly easy with an adapter you can buy to connect it to the power for the Homelink rearview mirror (if equipped). My guess it fitcamx uses the same type of adapter. I looked at the fitcamx after seeing many suggestions about it and the one thing that made me stay away from it is I was concerned about how easy it would be to get the footage after a serious crash. Having recently been in a serious crash in my last car with another VIOFO camera, I was able to simply slide the camera off its mount unhook the cables and now I had all the footage immediately to be able to provide to police and the insurance company. It didn't seem like getting the SD card out of the fitcamx would be that easy in an emergency and microSD cards are easy to lose in situations like that even if you did it get it out. This is just my personal opinion based on my experience.
