VIOFO HK3 Acc Hardwire Kit for A129, A129 Plus, A129 PRO, A129 IR, A119V3, Enables Parking Mode, Low Voltage Protection

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

Works like it should. Arrived before the dash cam.

Installed in a 2014 F56 Mini Cooper S.Like in all BMW cars, these hardwire kits will trigger a warning most mornings which will say "battery low voltage warning" even if you have the Viofo Hardwire Kit on its most conservative setting. It's never caused me any issues though and the car starts just fine. Will it harm the battery over the longer term? No idea, but doesnt seem to be causing any issues thus far.The Kit itself can be installed by anyone with decent DIY skills. However, there are some VERY important considerations (see below).TIPS:1. Research and identify which fuse you can tap! Never tap a fuse for a critical system like braking, steering, etc. Go for an accessory, something like AC, Power Windows, etc. AND NOTE, it must be a fuse that stays powered when the car shuts down completely. Some fuses will eventually turn off (usually 10m after your car turns off) and then your DashCam unit wont have power.2. Research how to remove interior panels if you want to hide the wiring through the pillars, roof, or carpet. You will break a few clips removing these things, but they are very cheap and I ordered extras from my local BMW dealer. You can do the same for whatever make you have.3. Adjust the min battery setting you'd allows before the system shuts off. I chose the most conservative setting because too aggressive of an energy pull can shorten battery's life.

I decided not to use this as it has a HUGE choke on the end near the plug. So, it can't be tucked neatly under the headliner. Very poor design.

Straightforward kit

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.

This is a must for parking to make double dog sure no one messes with your stuff. I put it in a 1957 truck and it's great. I have a video on YT: bobeaseshop
