I like how their phone accessory Seek Compact camera is advertised as having “< 9 Hz frame rate.” I’m sure it’s fine but that’s a strange way of listing it.

That's actually a "feature" for IR cameras because 9+ FPS brings it into a different category for export control.

Huh, interesting! It makes sense in that context.

Having never tried one of these, I wonder if they take that slow camera stream and do higher framerate image stabalization on the phone to make it less jerky when hand-held.
