The frame 5 & 6 do seem a bit fuzzy, i would expect to be reading the plates better in those situations.
But i am allso pretty baffled by this myself, it is as if some times dashcams choose a really bad setting and make bad captures, and the day after in what seem to be even crappier circumstances the camera use a better setting and make stunning captures.
I am not sure what this is or if its just me, but i have seen / had this feeling about all of my cameras, but most on the ones in my windscreen, and thats proberly due to me looking at ther footage far more often than the footage of the rear - right - left side cameras.
But i am not overly exited about this as i dont rely much in my cameras, and for the most i just use ther footage to expose crappy drivers on youtube, and for the most ther stunts is clear to see even with the most foggy footage.
But if i get a hit and run and miss plate capture you can be sure you will hear me bitch even more than i did when i was rear-ended in october and missed that due to a known flaky power supply to my rear camera.
What i have realized so far is having more cameras is a big +
I am stunned about what the L side mobius camera capture and for that matter the R side innovvC3 camera, for the most if what i can get off the front camera dont make me happy i am able to find somthing better on one of the other cameras.
Anyways no matter the brand or camera price, things will only get better.
