60 MHz is enough to fool the eye.

Normal long tube florescent lights flash at exactly 60 MHz. But the moment they begin to fail you start to see them strobe in some cases this looks like simply flashes in other cases it looks like pulse traveling from one end of the tube to the other.

Past around 100 MHz the human eye can't really tell the difference 120 is more than enough and 500 is simply excessive. What it does do however is make slow motion functions on the DVR clearer and blur far more reduced when observing action and adds to clarity but this isn't typical movie watching.
