They are not concerns.
A dash camera is expected to do 1 job reliably.
Record video while driving
So far all 3 I have tested have failed.
Customers all reported rear camera connecting and disconnecting while driving which means the dash camera is constantly recording stopping recording over and over again.
This is not 1 issue there are multiple.
The 70Mai T800 has a great interior camera. Yet again I am testing beta firmware after beta firmware to find the same problems with their unit.
Corrupt video files
Motion detection only works on front camera (but i can never get it to wake up and record anything in motion detection even from front camera) which is suppose to work
Many more challenges I need to go through my notes. I think I am on firmware #4 to fix issues.
Red Tiger F77

@rcg530 has a blog on it.
I think dash camera companies need to go back to the drawing board with the 4k rear cameras
