HK3 Acc Hardwire Cable for A119 V3/A129 Plus Duo/A129 Pro Duo Dashcam

This is a great three wire hardwiring kit and is the third of three that I’ve installed. The first was the Plozoe which was a two wire power supply. If only one power and a ground are needed it’s a great product with the best value as it includes 4 sizes of fuse taps that by themselves usually cost $7 a piece. It doesn’t have an selectable battery low charge feature. The second was the Power Magic Pro: what a piece of over-priced garbage. First off, it didn’t work out of the box which many have reported. You’re forced to retain the cigarette-like plug to adapt it to the dash cam, which makes it the most antiquated and inflexible of the hardwire kits. Warranty is voided if you remove the plug for more streamlined, less bulky terminals. The fork terminal for the ground is tiny; most grounding points that you’ll find will be M6 (10mm socket) or 1/4” bolts, so you either not find a suitable connection or have to source a larger M6 terminal to replace it with. The Viofo three wire affords you a battery power wire for parking mode and an ACC wire to wake up the camera when you start the car. The circuit board allows for multiple battery low charge protection limits and has nonproprietary USB connections. Hopefully this will become the new standard for dash cam hardwire kits. You must source your own fuse taps or splice into the vehicle power supplies which most pros suggest. The Viofo A129 Pro Duo with this power supply has been the best combo for the price, ease of use and performance. The small screen makes setup and monitoring current operation convenient and takes up a very small piece of windshield real estate. The Vantrue failed mostly because it would never wake up from parking mode (a three wire system would alleviate this problem). The Black Vue is very cheaply made for the cost. It has some nice features that make it an enticing option, but it’s in need of some serious updates and material upgrades to justify cost. The camera plastic is very cheap and the front camera jiggles around in the base. It also lacks a screen interface to quickly assess mode and operation. Save your money.

The wires themselves feel very quality and not cheap at all. They give you so much length that I'd be surprised if anyone managed to run out with their install. Works as it should and that's all there really is to it. Easy enough to install at home with the help of some youtube videos (even for an idiot like me when it comes to wiring/electrical work). Highly recommend for any Viofo cam owners contemplating the purchase

Does what it says it will do. I bought two of these for two different cars. Both have parking monitoring when car is off and battery has not died in either one.

Update: After talking with customer support, they sent me a tested working kit. They were quick to respond and send out the unit to me which I appreciated. The new kit works now, and my car has working hardwire with the parking mode! Old: Ordered a hardwire kit and after installing and troubleshooting for a while found the kit was DOA. Ordered a second one and it had the exact same problem. Does not provide any power when connected properly. I tested directly off the battery terminals as well as through fuse box and ground in car, no signs of power in either units. Seems to be a common problem with bad batches of these kits. Can not recommend viofo after this terrible experience, wasted hours of my time.

Installed a A129 Plus Duo on the wife's car a couple weeks ago and used the kit. Everything went together great. At the moment she's not driving much at all, her car sits for a week or so at a time, after the install I set the kits volt meter to 12.2V and in about a week after I last drove it I came home in my car and noticed it wasn't recording and the record light wasn't even blinking. I figured the kit must have shut down the parking mode to save the battery. When I got her keys to see if that was the case, sure enough the car started just fine and once running for a few seconds the camera came to life and started recording. Once she starts driving regularly again I'm confident that the kit will make sure her battery does die on her, specially with winter upon us.

The old power supply failed. This on is much better, heavier gauge wire and coating.

I used a couple of these to hardwire dash cams into my two vehicles. They were plenty long for the job, and I love the fact they ensure the dash cams can't drain the battery too much in parking mode. My only complaint is that the fuse taps the instructions recommend aren't included. Regardless, great product.

Both times I have purchased these (for two different cameras) they haven't worked. One completely stopped working after a few days and the other made the camera do weird things when the car turned off. I would come out to the car the next day and the camera would be constantly beeping and lights flashing, even though it was not doing that for the first hour the vehicle was turned off. I took it out after reading a review here that said this hardwire kit broke someone's camera altogether. Honestly the worst part about it is the time you have to invest researching the fuse tap, the fuse you need to use, then hiding the wires only to find out it doesn't work. Then you have to pull it all out and go back to using the 12v plug that came with the camera. I would be super angry if I had to pay someone to install it over and over again because it kept breaking. The A129 Pro Duo has been a great camera for several years for me. I do not understand how this company can make something so good and yet cannot get their simple hardwire kit to work. Customers have been complaining about this hardwire kit for years. Change your design or change production facilities! You obviously have massive quality control issues for this product, Viofo. You are losing customers, including myself. I want a dash cam that can be hardwired to my vehicle so it can run while I'm away, RELIABLY. That's why I won't buy another Viofo when it's time to upgrade. My next camera will be Thinkware.

A must-have if you want your camera in parking mode. Works well and I like the different voltage cut-off settings. I have installed several of these on different vehicles now and I've always been satisfied.

also tut bisher was es soll, kabel sind lang genug, der knubbel (ferrid) nervt bei der installation, installation ist nicht für jeden etwas, da sollte man schon grob wissen wohin welches kabel und woher.. Der einzige Kritikpunkt für mich die per schieber einstellbaren spannungen (entladeschutz), höchster wert sind 12,4v (24,8v) das sind bei agm nur noch 60% bei regulären immerhin noch 70% ladung.. ausgelierfert wird mit 11,8v (23,6v) da wird es schwierig mit auto starten, entspricht nur noch 20%.. gut die cams brauchen im parkmodus auch nicht mehr so viel trotzdem find ich das schon grenzwärtig.. lieber wären mir die 4 stufen:12,2, 12,4, 12,6 und 12,8v.. enspricht etwa regulär 50, 70, 90 und 100%, agm 45, 60, 75 und 90% ladung..

Indispensabile x dash cam Viofo

VIOFO hardwire kit, this is second time I've purchased this, once for my car 2 years ago and now for my partners new car. Very happy, be sure to check your fusebox properly for which leg is live - plenty of guides/forums online for every car, easy self install. Paired it with a VIOFO A129 Plus Duo.
