VIOFO A129 Duo Bundle with Low Light Vision | 2 Channel 1080P Front and Rear Dash Camera for Cars | WiFi GPS Mount | 3-Wire Hardwiring Kit and Installation Kit Included

I have purchased two of these. One I purchased on 1/16/19 and after it was installed and working, I purchased another on 1/26/19. Both of these are connected using the 3 wire wiring harness that was included and connects to both constant and switched power. I also set the low voltage switch on the harness to 12.0v on both installs. The kit came with circuit taps for several fuse types and I used what was supplied with both installed.The first one was installed in my kids 2008 Honda Civic coupe. There was a little learning curve getting it setup but it wasn't too bad. One tip is after you get the wifi turned on and connected to the IOS or android app (I used IOS), update the firmware first thing. Once the install was complete, the image looked great on both camera's. The Civic has tinted windows, so I adjusted the exposure on the rear camera +0.03 as I recall. One setting on the positive side anyway. I did the same thing on the Explorers exposure setting for the rear camera since it is tinted from the factory. I like how you can view and download files from your IOS device as well as all of the configuration settings. Getting to the fuse panel on the Civic was easy as was finding constant and switched power.Since I was happy with how everything was working in the Civic, I ordered the same kit for my wife's 2018 Explorer Sport. Installation was more difficult on the Explorer since I had to run and hide the cabling from the front to the back and it is a much larger vehicle and the location of the fuse panel in the Explorer is in a terrible location. There was also left over cable on the Explorer install (and a LOT on the Civic) meaning that this kit could probably be used in a larger vehicle. Either way, installation was as straight forward as the Civic and everything went in well. So far they are both performing well although I have less than a Month of experience with the a129 Duo in total.If you have done this sort of installation work before, this will not be a big deal. The kit combination gives you everything you will need for the install except for the SD card. I have a 128GB SD in the Civic and a 256GB SD in the Explorer. The memory I used for both are Samsung EVO Select (https://www.amazon.com/gp/product/B06XWZWYVP/ref=ppx_yo_dt_b_asin_title_o02__o00_s00?ie=UTF8&psc=1). If these continue to function as they are currently, I plan to purchase two more for our other two cars. If and when that happens, I will update this to 5 stars.

While overall satisfied with a129 I believe documentation needs better description of supported memory cards.Currently it states: "The microSD card must have a Class-10 or UHS-1 rating". By trial and error I had to find out that this statement is wrong and I was about to return this dash cam in the beginning.I am glad I did not, because camera itself is really good and does what it needs without extra bells and whistles at a very reasonable price.Now this is what I found about cards:1) cards that have only Class 10 logo do not work, these are pretty old cards anyway.2) cards that bear UHS-3 logo and claim backward compatibility with UHS-1 do not work either3) the only cards that work for me bear both Class 10 and UHS-1 marksI ended up with SanDisk 128GB C10 UHS1 and dash cam was able to format it and it works as it should.There are four stars because of unclear documentation. Hardware is good while interface is a bit sluggish, but I do not use it much anyway.

Pros:-camera kit comes with most everything you'll need to install. I like that it came with multiple panel removers which I kept to use for future projects as well as a basic test light. You'll need to use basic hand tools to install which depends on your vehicle. Ratchet, screwdriver, wire crimper etc.-came with multiple, different sized, piggy back fuse connectors with fuses.-came with its own cloth to clean the glass before mounting.*WILL update in the future for picture/video quality and durability. I live on a tropical island where outside temps can go as high as 99 degrees.Cons:-rear camera is difficult to mount high on the rear glass of a truck. I installed mine on a 2016 Toyota Tacoma. It's difficult because the glass is flat unlike a car which has its rear glass at an angle. The flat glass makes it difficult because if you tuck the wire in the headliner then the USB connection to the camera is strained. UPDATE: I turned the camera the other way so that the USB port faces down. I then extended the USB cable to be able to connect the cable to the camera and used a wire holder that came in the kit to keep the wire in place and look nice. I then used the seetings to flip the video right side up and it works perfectly fine.Update: 04/15/19-Rear camera no longer connects to front camera even though all wiring is in place.- Camera is hard wired to constant power source yet will shut down and stop recording even after vehicle has been started. Usually have to disconnect power source at the camera and reconnect power source to get the camera to start working again.

Just like another reviewer pointed out, the rear camera USB port failed after only a couple month. There's plenty of slack in my cable, it was installed properly. I noticed the rear camera not being detected at times, and sure enough when I checked the cable connection on the rear camera, it was defective. The entire thing felt "loose" inside the body of the camera.Second issue is the interface software is super buggy. Sometime you can enter the menus, sometimes it completely ignores your input. Sometimes you can turn on the wifi and connect, other times nothing.And yes, I am tech savvy, I only attempt to enter the menus when parked and recording is stopped like the manual states. It just doesn't always work as it should.Video quality is really good! But I cant give this thing a decent review if the rear camera (which never is even touched) slowly falls apart on its own in 4 months time.The bad interface software doesn't help either.
