Hello fellow Brian with a i
And mariov24, welcome to the forum.
Not at all familiar with this brand of cameras.
I personally use low bitrate always record for parking guard, and in that case the footage are just in the regular footage folder, i would assume it would be the same if i was to use time lapse for parking guard.
I do also have G-sensor on when parked, so any actual events will get locked or at least act as a flag for when something have transpired.
It sound as if a bug have sneaked in with the new firmware, or it could maybe be if you have not done a reset to default after you have installed the new firmware ?
Other thing i can thing off to see if it change anything are to run the system with the regular power supply and not the hard wire kit, just for a ride to see if that make any changes.
Though it do sound as if you both have had the thing working normally.
Many years ago i did have a test camera that backed itself into a corner, and became "faulty" in some way i can not recall, but not like you guys see for sure, anyways back then flashing the same firmware again took care of the issue, and with the following 5 - 10 new firmwares the problem never returned.
Most newer cameras i have tested though i have not tested this, it is my understanding that some part of the memory card space are assigned for the event folder, but when that fill up even there in the RO folder ( Read Only ) the footage will then get recycled as the camera also do in normal mode when the memory card is full.
I did test this on a Street Guardian system a few years ago, with it running on my computer table and them me flicking it now and then to create a event, but i cant recall how much of the memory card space was actually used for this, but i do remember i did notice that it was a adequate number of event recordings there was room for.
Me not generating events at all aside for pressing event button when driving, and that if my car would get hit while parked, which have not happened
So me using 256 GB memory cards, in my RO folder i have events going back many many months, so long that when i get around to pick new files for a upload to youtube i have to look at mu last video to see which files i have already used 1 time.
