going by supported features (even though they list some other model number) I'd say the F750 is most likely using the A7LA75 processor, what sensors they use I'm not sure
@alexsoll, sorry but you are unprofessional in any point of your review...
Thinkware F750 has A7LA85 with IMX122, and this is the world firs Dashcam which use Ambarella A7LA85....
That A7-A0-RH is just name for advert....
so far Datakam G5 DUO was close to be first (but still is not released yet).
next time if you not sure please don't write nothing in review, or just say "I'm not sure/unknown" because other people can be wrong after your "review" and chose other camera with A7lA70.....
