The A129 is the highly anticipated 2-channel dash cam offered by Viofo. It takes advantage of the Sony Exmor R Starvis Image Sensor along with a new and improved lens to offer Full HD on both front and rear cameras at 30 frames per second. With the VIOFO app, taking out the memory card will no longer be necessary as it provides live preview, video download and playback, and settings adjustment. It also offers a 2" HD screen which allows for easy setup and playback of videos as a convenient alternative to using the VIOFO app.

What is Parking Mode?
Parking mode is offered on most of the dash cams available at BlackboxMyCar. While it is important to protect your vehicle while driving, it is just as important to have your vehicle protected while it is parked. When the dash cam is in parking mode, footage will only be saved when there is an impact and/or motion. Parking mode can be enabled with a hardwiring kit or a battery pack.
For more information on parking mode, click here.
What is a Hardwire Kit?
A hardwiring kit enables parking mode. It allows your dash cam to remain powered on even when the vehicle's ignition is turned off. Installation is a breeze as you will only need to find an accessory fuse, constant fuse, and a grounding point.
What is a Battery Pack?
Most customers purchase the battery pack to avoid using the vehicle’s battery to power their dash cam. The battery pack is charged by either being hardwired into an accessory fuse or by being plugged into one of the vehicle's 12-volt cigarette sockets. We recommend the hardwiring the battery pack as it charges the battery pack quicker.

How much footage will my memory card store?
On average, a 2-channel dash cam writes 16GB/hour and a 1-channel dash cam writes about 8GB/hour.

Do I need a Rear Camera?
Accidents or events don't always happen at the front of the vehicle! Having a rear camera provides coverage for any events or accidents that may happen at the rear of the vehicle.
For more information on rear view cameras, click here.
Do I need a IR Rear Camera?
An IR camera is designed to record the interior of the vehicle in low light conditions. This option is very popular among rideshare drivers.

What is a CPL filter?
A CPL filter attaches to the dash cam lens to eliminate lens flares, light reflections, and windshield glares.

Overall the camera is decent. The site's service is great. Camera is mostly good. Night time videos has lots of halos/streak
I tried to use the financing option to pay for the camera. Story of my life, I was rejected for some stupid reason. I also had a lot of hours cut from work, so I didn’t get paid a whole lot. I ended up having to make the purchase in full, which left me with very little money. Other than that (I’m not holding it against anyone; the universe hates me lol), my experience shopping here was excellent. I didn’t have to pay any sales tax like I thought I would and shipping was free. The camera also arrived one day earlier than the initial estimate.
The system has been installed in our vehicle for only three or four days. I wanted to get the hardwire kit, but that’ll have to wait until next pay check. The power adapter that was included seems a little questionable. A little green disk lights up when it’s receiving power, which I like, and it includes two USB ports. I assume one to power the camera (duh) and the other for your phone or whatever. It has a three amp current output, but I don’t know how much the camera system uses. I figured probably 2 amps for the camera(s) and the last amp for your device. I didn’t like that it doesn’t list the input current, but that could just be me being picky. The power cord is plenty long enough for us. We installed it so that the cable runs out of the camera and then drops straight to the floor and back up to the power adapter. Absolutely nothing fancy about it. Well, we have a medium binder clip clipped onto one of the hvac vents and then the cable is ran inside of the...the flippy things you squeeze to open the clip.
The rear camera was a different story. I used the included wire clips to take the cable across the top of the windshield (to the passenger side), then I sent the cable over the sun visor, using it as support. Then I used the little hook over the back seat (the one you can put hangers and stuff on) as another support (did I mention this is an 05 Chevy cobalt). I then used another of the included hooks to hold the cable to the back windshield. There was a lot of leftover cable, so I lowered the back seat backrest and dropped the excess behind the seat. I do wish that both ends of the cable were angled or that the connector on the rear cam was angled. I had to place it fairly low on the window to allow the cable to plug in. It would also be pretty cool if there were some bigger cable clips included too so that I could stuff both cords into one clamp. I’d only need a couple though, as the two cables would depart ways early in the routing.
Installing the camera system was easy. Maybe a little too easy. I found a great spot to place the front cam first. It was right behind the rear view, and the mesh allowed me to get the camera installed level. I took the film off the sticky pad and very gently touched it to the glass to line it up before pressing it firmly. I got it just a little bit uneven, but the sticky pad had already taken a strong hold to the glass. It isn’t noticeable at all, which is good because I never got it unstuck to realign. I did take the gps unit off (since it is the base) and mounted /it/ to the window.
The rear cam went about the same, but I did have to peel it off a few times. Once because I misaligned it, again because I couldn’t fit the cable into the port, and yet again for the same reason. Other than those nuances, installation was fairly straightforward. I also downloaded the app (which only has two stars on the App Store!!) to assist in the installation (yay for live view lol). My first issue with the app was when I put my phone into landscape mode. It would seem like the app developers would have accounted for people who rotate their phone in different directions. I flipped mine in a direction the app wasn’t proud of, and I was getting an upside down view of everything. Of course, when I flipped my phone the other way, the view was right side up. But surely that’s not the reason it was given only 2 stars (I’ll come back to this. I’m writing this review chronologically).
The captured videos are massive in size. Almost a half gigabyte or more for a 10 minute recording. The instructions imply the cameras WiFi has a 5G mode. Either this is wrong, or the option is very, very well hidden. It takes about as much time to download a video as the videos duration is (10 minutes for a 10 minute video). It looks crisp on smaller displays, but on a 1440x1080 monitor (which is basically standard these days), the view becomes degraded rather obviously. As with basically all wide-angle cameras, it’s hard to get a good judge of distance and speed, which is part of why I wanted the gps (the leading factor was so that our speed would be stamped in the video, so no one could claim we were speeding or something if something happened).
Next came what I’m going to refer to as long-term testing. When I initially tested a video, there was still plenty of free space left on the included uSD card. My precious camera gave a weird issue. It’s videos ...
The VIOFO A129 Duo provides a good picture for the price point. The only thing I dislike about the VIOFO A129 Duo isn’t the camera itself but the rear camera cable. The rear cable is considerably thick and provided a challenge with cable management and I couldn’t tuck or hide it in certain curves of my car without tearing or breaking parts of my interior, and yes I tried using the trim removal tool. My car (2019 VW Jetta) might differ from others with the seams, plastic, and fabric so it is probably on a case to case basis. I will keep this in mind when I'm looking to upgrade to another camera.
