I myself as a professional driver often has to abärgern with idiotic and dangerous actions of other road users, I have here at Amazon this dash-cam concerned.
with all kinds of settings (including exposure time reduction motion blur for less) and tests of the same, are the hallmarks of preceding vehicles can only be read in blatant fall below the legally prescribed safe distance - here only on a much larger display than on the device's own, and then only as a still image!
at night, all lights can be seen streaking just over bright, otherwise you see nothing but black!
who wants a dash-cam set only for mitfilmen the distance traveled, can be accessed here ...
for all other purposes but is this unit unfortunately totally unsuitable!
my conclusion:
Not advise !!!
