I have a Blackvue DR750S-2CH that started just shutting off this spring. I’ve had the camera since August of last year and had no issues with it throughout that hot Georgia summer.
The issues started after one of the firmware updates (I forget which one), but in my garage, with the car sitting at about 85 degrees I could barely touch the camera it was so hot – and this was in parking mode. Something was making it’s CPU work overtime.
I went back and forth with BlackVue three or four times. It almost seems like they try to just keep you occupied while they test and prep the next firmware release.
Anyway, the solution was to reformat my SD card and basically install the firmware update from the SD card directly rather than pushing from the phone. I installed the 1.010 firmware update.
It’s been over two months now, through the height of summer, and I haven’t had any issues. I just went out to the garage and touched the camera and, while warm, is NOWHERE near as hot as it was when the issue was manifesting.
So there seems to be hope, at least in modestly hot regions like the SouthEast. Not sure if you desert-dwelling folks can get the same relief.
Below are the instructions I followed:
