@losang30 I have the Viofo A329S 3CH system with the HK6 hardwire for power.
I do not have any SSD, I am only using a Viofo 512gb Micro SD card.
I have noticed, maybe 2-3 occasions where the single power LED I selected to indicate
parking mode is ON, and it is OFF when I get in the vehicle. I check the settings and
find the Parking Mode is set to OFF.
This has only happened when parked in my driveway, and whenever I am home I plug
my vehicle in to a battery maintainer to keep my car battery charged and to make sure
my dash cam has power. I have no idea how or why this has happened.
But - just last night I upgraded my Android phone to the newest Beta version of the app,
and also upgraded the A329S to the latest firmware, so I am curious to see if I experience
the loss of Parking Mode again. This happened 2-3times over the course of about 3 months
so it be a while before I see it again, if ever. Also, there are some new features included in
the latest firmware, features that I am not yet using. I want to see how the new firmware
acts with all the same settings as before, prior to making any new settings.
My selection for Parking Mode is: Hybrid, Low-Bit-Rate > Impact Detection.
Hope this helps.
