I bought this camera for both front and back view of the car, due to a recent event. Thus I realised in this day and age a dash cam is a must. The day time visual are excellent. The night time are ok. The back camera is for formality only and night time is unimpressive. Overall happy with the purchase expecting it to run couple of years. Fingers crossed. It was an easy install as well no dramas. I think 32GB is good enough becasue added memory does not make sense to me as i only record during driving. The card can be formated in Camera. For setting used FHD, Exposure, -1 if you live downunder, for overcast days or winters you can have it to +1 (higher will over expose, resulting in whitish results), and refersh rate to 60 Hz will improve the camera quality in great way.
