I prefer to have G sensor off while driving, even if Danish roads are not too bad in general, but for the amount we pay in tax here the roads should be paved with leaf gold and be resurfaced every year.
And my driving style are now so moderate it alone would not set off the G-sensor. Some times you can not turn G-sensor off in cameras i test, but they are now tuned better so on low i get very few false event triggers.
For parking guard i prefer the always record low bitrate option, but here i will also have the G-sensor on as low bitrate are just regular footage so will get overwritten for sure. Also the G-sensor locked files will then act as a beacon of where a actual event happened, otherwise if parked a long time and you had a event you have to sit thru a lot of video to find out what happened and when.
If event files are permanently locked, as they was on old dashcams then you run into a couple of problems.
1: the whole memory card would be full of read only events, leaving 0 space for regular files.
2: the assigned memory space fill up, and then can not hold more as it is full.
So i feel there should be some recycling of memory space here too, but for sure you do not want to low ball your memory card size, you having 256 GB is fine in my book, it is what i use myself mostly, only for memory card compatibility testing will i use smaller cheaper 128 GB cards ( i am retired so just have my pension )
A few years ago i tested with a SG camera to see how much of the memory space was assigned for events, doing that with camera running on the computer table just press the event button once in a while.
This was mainly done as SG cameras save 2 files from each cameras, so as it was a dual system i would get 2 X 3 minutes from each camera, a seemingly whopping 12 minutes in a event, but it held plenty of events for me not to worry about it, actually now the 2 file events are what i prefer as if you just lock 1 file, it could be bad timing if the event was right after the start of a new file ( not much before ) or if you was at the end of a file, not much after the event.
With the SG cameras working like that using 3 minute files, well you would at least have 1.5 minutes before or after the event ( worst case scenario )
so if current file are less then 50% done, a event would lock it + the previous one, or if the current file are more then 50% the current file would get locked + the next one.
At home i have CCTV on my car, and i felt 1 hour was fine as it cover all my shopping, but i do visit my sister now and then, and that took out my rear bumper on Thursday, and if it wasent for a witness taking down number plate on the girl that did it i would have been so screwed, as a good year ago i changed from full coverage to the minimum coverage which generally only cover the damage i might make on other peoples cars.
So god the tough love of a tow hitch, and my fragile little red car did not like that at all.
