Power issues

I am using the HK3 hardwire kit to power my 129 ProDuo. The power is plugged into the side of the camera. After anywhere from 2-15 minutes of driving the camera shuts down but will restart if I push the power button.

The red wire is plugged into a hot fuse (constant 12v regardless of key position) and the yellow wire is plugged into a switched fuse (0v when key is off). I thought I received a bad hardwire kit so I got another one but this one does the same thing. Parking mode is turned off and I have tried resetting the camera and multiple formats of the SD card. I am running firmware v2.1 which came with the camera.

What am I missing?

Certainly sounds like a power issue. Try plugging into the mount instead of the side of the camera.
Is the camera actually turning off, or is it just stopping recording?

The red lights turn off so it appears to power down. The odd thing is that I get the startup sound just before it powers down.

This camera is different from my old A119 so am I making an incorrect assumption?

I would double check your crimp connections to the fuse taps. Also check your ground. Be sure you connected to the metal framing under the dash, or better yet, there should be a grounding bolt near the fuse box.
Sometimes the pre attached end connector for the ground wire can sort of break free, so make sure that seems OK (maybe wiggle it a little while the camera is on to see if the camera loses power).
You could also power the camera using the included 12V car adapter and Viofo USB power cable. If the camera doesn’t shut off using that, then it points to the hardwire kit or it’s connections.

Thank you for the suggestions. Today I checked the crimp connections and the ground. All were solid. I am connected to a grounding bolt. I had it power down twice today while in my driveway stationary. A loose connection is unlikely. When I power the camera with the VIOFO power cable it powers up and down properly. Is it possible to have purchased TWO faulty HK3 kits?

Seems unlikely, but possible I suppose. Did you try plugging into the mount instead?

Since it appears fine with the supplied 12V car adapter and Viofo power cable, I'd still lean toward a connection issue or faulty hardwire kit.

If you have another memory card, I would give that a try too. What card are you currently using?

I am using a Sandisk 128G high endurance card. The camera operates normally using the VIOFO power cable which makes me lean toward a bad HK3 kit but have a hard time believing I got two bad ones. I will continue to experiment and my Amazon return is good until the end of January. 3rd time is the charm?

Yeah, seems unlikely to get two bad kits.

Are you using the same fuse slots in the fuse box that you did with the first kit? If so, maybe try a couple different fuses.

May want to try to reinstall the firmware as well.

Did you install V2.1 or did it come with it?

You should use a multimeter to check the continuity of the connections. That will make sure they are good. They may appear good but still not have good contacts. I'd also check the fuses and power through the fuses with a multimeter. Check both legs of the fuses.

It came with V2.1 AND I reinstalled it. No change. I checked voltages at each fuse I tried and got battery voltage > 13 volts.

I also noticed that when I turn off the truck the camera does not power down (when I can get it stay powered up long enough) so I just left it. Parking mode is turned off yet it stayed powered on all night. I pulled the yellow wire from the fuse tap and it stayed on. Then I pulled the red wire from the fuse tap and it powered down after a few seconds.

I either have a bad camera or have gotten two bad HK3 kits.

Made an account to just say that I have the same problem!

HK3 with A129 duo.

Camera will turn off (VIOFO screen/red light turns off) 2-4 minutes after the screen dims. Pressing any button will start the camera up again (VIOFO screen flashes, recording starts at 00:0, then 2-4 mintues later the camera (not just the screen) will completely turn off.

Further, the camera will start / shut off with the car approximately 50% of the time.

Continuity is good. Fuse locations are correct.

I have been emailing with VIOFO tech support but have not gotten any direction for things to check. All my troubleshooting has been my own and some ideas I got on this forum. Please chime in here if you have any breakthrough.

I would contact your sellers and troubleshoot with them.

You guys have two different models, so your issues may sounds similar, but are likely unrelated. Unless, the issue is the hardwire kit, then maybe there is a bad batch. Hard so say until someone with a working system can test one of your kits. Where did you guys purchase your kits?

Bad news / Good news

Bad news: VIOFO tech support is useless. All my troubleshooting has been fruitless. I purchased my camera from Adorama through Amazon so I get no help there either.

Good news: I purchased my camera through Amazon so it’s all going back for a refund.

I really wanted this camera to work. The video is great quality and it is a good price for the features you get. Until the US figures out how to manufacture a good dashcam I will have to switch to Korea. Oh well.

I bought the VIOFO hardware kit and camera through the VIOFO store on amazon.

That’s unfortunate. Adorama should be helping you since they were the seller.

Just adding another data point as I am experiencing the same problem described above. Purchased my A129 Pro Duo from BlackboxMyCar Amazon store on 12/3/20 and my Viofo HK3ACC cable from OCD Tronic Amazon store on 11/6/20. My SD card is the SanDisk High Endurance 256GB card.

The camera does not consistently boot up when the car is driven and will randomly shuts down for no apparent reason. It can be restarted by pushing the record button.

App version 2.1.1
Firmware: A129Pro.V2.1.20200803

If it is randomly shutting down while driving, test while using the supplied 12V car adapter and Viofo USB power cable. If it does not power off randomly while powering this way, then you can realistically assume the kit is the issue.
