problem sounds heat related rather than wifi being the cause, were the last files corrupt on that instant shutdown?I just tried it after it cooled down, and it shuts down cleanly:
The second video on the first post was with WiFi off and hot.
that's not a good sign, will easily get to those sorts of temps for most users in summer, they'll need to look at this and see what's going onWell when it is very hot (unit 65C) nearly always pulling the power out doesn't cleanly shut down, the file is corrupt and the dashcam lights instantly turn off. Wifi on or off doesn't matter, neither does quality.
So powering off in a hot car might lose your file.

I am going to leave it on in a box where it gets hot and see if any files end up corrupt and will let you know. It gets to about 70C.
I've only checked if pulling the power is a clean shutdown or instant power off. This seems to consistently happen when it is about 68C. Wifi, 2K or normal, bitrate, and IR illuminator make no difference.
It didn't happen when just using two cameras but it didn't get quite as hot.
MKV is just a container basically the same as used MP4. None of them are related to anything what is inside.Shame they don't use a format that still works if not cleanly shut down, like MKV or something but whatev. It can probably be recovered in a pinch.
