Very good quality in day light, at night its just fine.
At lowest resolution 1920 x 1080 with H265 and a 64gb card, it will record for around 10hrs.
Will test for H264 and other resolutions and will update the review.
One thing I want to mention here, I think this dash cam is not made for Indian roads. In case of a speed breaker or a small bump it starts recording emergency video. This is when the sensitivity is set to low.
