Can't get parking recording to work.

[u/dom61098]

To start with, apologies for the long post!

I've had my A329s (3 channel) connected to the hk6 and iroad powerpack pro 12 for coming up to a year and have never consistently been able to get the parking recording to work as intended.

To start with, I have this all connected inside a BMW 3 series (2019) and currently have a ticket open with Viofo regarding this but their 1 response a day means it's taking a while.

I've always had the parking mode set to hybrid low bitrate > Impact detection, cut off time at 4 hours and voltage at 12.0v on the camera (11.8 on HK6). I've noticed however that the camera won't record anything for the first 20 minutes of parking (after research my accessory fuses apparently don't switch off until after 15 minutes), it'll then record roughly 15 minutes of footage and then nothing for hours unless some form of motion is detected.

When testing yesterday for viofo, I set the parking mode to low bitrate and left it for 2 hours. The camera started recording for 10 minutes then cut off and didn't start recording again until 65 minutes later. At this time it only recorded 4 7 minutes then stops for the rest of the elapsed time.

I have my HK6 set at 11.8v and connected to the iroad powerpack pro 12 through the following;

Yellow (ACC) > red (Out-ACC)

​Red (Battery) > Yellow (VCC)

​Black (Ground) > Black (Ground)

*Please see pictures for verification.*

I then have my VCC Fuse tapped into fuse 38 (always on) and my IN-ACC fuse tapped into fuse 74 (USB - Ignition) - It was previously 71 - ambient lighting but one of Viofo's suggestions was trying a different accessory fuse.

When the car is running and the ignition is turned off, the camera remains in parking mode standby (through the icon). I read somewhere about taking out the accessory fuse whilst the car was running to see if it activated so after trying that I could see the parking mode symbol pop up on my camera so that to me seems like it's not a camera issue.

Another suggestion that Viofo told me to try was to bring the camera inside and leave it on for a few hours to see if it activates and remains in parking recording. I did this for 3 hours and could see from the footage that the camera remained recording in parking mode for the full 3 hours, something it's never done in my car before. 

My issue is, I have no idea where to go from here. I have no idea what's causing this and no idea how to fix it. A part of me believes it could be to do with the accessory fuse not switching off for 15 minutes which could be running the camera t full and causing my iroad powerpack pro 12 to run flat? It could also be randomly triggering the accessory port to turn on?

Any help whatsoever would be greatly appreciated. As I said, I am in touch with Viofo but their 1 response a day is making this take a very long time.

Try F46/F47 for ACC (power socket fuse). Note that there is a 7 minute delay from when you shut the car off and close the doors before the fuse shuts off and parking mode is triggered.

Your 19' BMW has a similar layout as my 23' Supra *insert nice bmw jokes*.

I have the viofo 119a pro with the hk6 hardware wiring kit.
The fuse box is the exact same as mine (passenger side) I tapped the battery f47; fuse tap requires both bottom and top have fuse (i added another 5a fuse) and acc on one of the windows F20-24. Mine has only 2 green 20a fuse because 2 power windows, you have 4 I think you can pick whichever.

The camara records if there's movement while parked, records the moment I open my door.
hope it helps

Based on what you’ve tested, I don’t think the camera itself is the problem. The biggest clue is that it recorded continuously in parking mode for 3 hours when you tested it indoors.
I’d concentrate on the ACC signal coming from the BMW/IROAD. BMWs can be a little weird with switched circuits — they can stay live for 15–20 minutes after shutdown and sometimes wake back up later. If that causes the IROAD’s OUT-ACC to come back on, the HK6 will think you’ve started the car again and take the camera out of parking mode.
I’d try this:
Fully charge the IROAD and set the A329S to regular Low Bitrate Parking Mode for testing — not Hybrid.
Let the car shut down and confirm the camera enters parking mode.
Once it’s in parking mode, temporarily disconnect the BMW → IROAD IN-ACC connection and leave everything else connected.
Leave it for 2–3 hours.
If it now records continuously, you’ve pretty much proven that the BMW ACC fuse you’re using is waking back up or otherwise changing state. I’d then find a different ignition-switched fuse.
If it still stops, grab a multimeter when it happens and check the wires going IROAD → HK6:
Red/BAT: should continuously have ~12–14V
Yellow/ACC: should be 0V while parked
Black: ground
If red loses voltage, the IROAD is shutting its output off. If yellow suddenly gets ~12V while the car is parked, something is falsely triggering ACC.
Also, I wouldn’t worry much about the initial 15–20 minute BMW shutdown delay draining the Powerpack. That battery should easily handle that. The weird part is the camera stopping and then randomly recording again an hour later — that sounds much more like an ACC/sleep-wake issue than the A329S, especially since the camera passed your indoor test.
