Hi bro, interested in buying this model 6000.
Regarding with the video quality, can I know why the night vision having clearer view on the car plates compared to the day time video?

I am having MicroSD 64GB, can I still use for this cam?
I don't mind it detected 32GB as long as I can use the MicroSD.
Can I know roughly how long the recording will last to fully use up all 32GB?
And also, once the space is full, will it overwrite the old recordings or it will stop recording at all?

Appreciate for your kind reply.
