That Qualisys model - the mcu 240 - seems to only have a 240fps capability at less than SD resolution... You can find that slo-mo capability in some modern camcorders at much higher resolution these days. Can't see any point in buying that (...and a £500 price tag? --- he's having a laugh! ) )
The Kodak is more interesting. Captures at (up to) 10000 fps apparently... although only at fairly low resolution - and to DRAM, so probably for only a fraction of a second at that speed....
Capturing at higher frame rates than around 240 is still pretty specialised stuff - and modern hi-res cameras - like Phantom Flex for example - are way more advanced than that 20 year old Kodak technology... (understandably)
So IF it's all actually working it might be interesting to play around with......but again not at £500 -- more like £50 I would have thought?..
f there is anything wrong though, you might have fun trying to get it fixed?....
With really high speed capture it's still hardware limitations - rather than software - and that's what makes it all so expensive. AFAIK, Phantom Flex cameras - for example - will cost around £50K - and that's why many people just hire them, when they need them....
