The frequency is 1 Hz of course, but the waving proves this is filmed with a DSLR because of the shutter moving vertically.

Not necessarily a DSLR. I have a Kodak Playful miniature DV which would do the same thing.

Any CMOS at 60Hz will display a result like this. A CCD will just show the speaker cone moving in and out at an apparent 1Hz.
