But what is the reason for that much FPS?
These types of cameras are not GoPro or Hollywood type cameras that offer slow-mo capabilities and other features. They "offer" 30FPS and 60FPS to appease the general public that thinks that is what they need, but you will not find many of us here running more than 15 FPS; and movies are shot at 24 FPS, so anything above that is a waste of storage space for what these cameras are used for. If 24 FPS works for the big screen, I think 15 FPS is more than enough for phones and tablets and most monitors LOL. Many of my cameras are running at 12FPS.
If your unique case requires that type of FPS, you will find surveillance cameras are not going to meet your needs and you need to get a camera capable of that - or spend some serious money.
We have had recently people come here after purchasing cameras in two instances where they were wanting 60FPS - one was a tennis club and another was a youth soccer club. In both cases they found that these types of cameras were not capable of what they were wanting to do. Sure the cameras could run faster FPS, but it still didn't provide them with the level of detail they were looking for. I recall the soccer club had a decent quality PTZ ($800) that is fine for a residential or retail/commercial installation, but to cover the action of the soccer field it wasn't capable of meeting their needs. And because of the extremely fast motion, it was creating a halo type effect around the action (which can be seen in certain lighting conditions). These cameras are good, but not good enough to catch the rotation of a ball for example.
