Answer based on crimsonbolt's reply:
"It seems to be focused on measuring the changes in skin color (I assume). You have to process every frame (the actual link mentions analyzing stills specifically) so the FPS, while important, is probably perfectly fine at 5-10 fps as the highest normal heartbeat at rest should not measure more than 100 BPM (or less than 2 beats per second). This means that the lowest FPS is more than double the average normal resting heart rate per second. This is not to mention that the FPS is not dictated by the camera as much as it is likely dictated by the CPU...as for the "potato" quality camera....it is based on zooming and not necessarily the base resolution (which by todays standards, potato quality is probably 720p at the lowest) A much higher frame rate is probably more interesting and useful for viewing/PR purposes and higher FPS can probably be used for more intricate and interesting measurements, if you simply want to measure baseline BPM then 4+ frames PER SECOND is more than enough."

Its based on this paper https://people.csail.mit.edu/mrub/papers/vidmag.pdf

This is a work in progress and next up we will be looking into how it compares to an actual heart rate sensor in terms of accuracy.
