I've just recently installed the 70MAI Dashcam Pro into the Mazda, I'll have to check daylight footage however dusk/overcast footage looked good at the resolution I had selected [higher than FHD 1080 but not 4K] .. you can pick them up from Aliexpress by
clicking here.
I also have an older BlackVue DR650-2CH that was in my old Mazda which I will be installing into my i30.. That's a 2 channel FHD 1080p front facing camera and a HD 720p rear facing camera setup .. It works very well and is still nice and clear. They certainly have got new versions out now though and the
DR720S-2CH is about the equivalent version of my old one.
A quick google for reviews will bring up sample footage for each.
