A:AnswerThese cameras only record at 15fps using 4k resolutions. A recording quality~2k or less can be recorded at 30fps. Lorex cameras have the ability to record 4k @ 30fps but they are not in this set. For some reason, best buy is not selling the new tech stock yet. (disappointing) Perhaps because Lorex has the new technology cameras listed just under $600.00 each, putting this would be, 4 camera system around 3,000.00. It's a lot to pay for an addition 15fps, (@ 30fps)
