Hi,
I am searching for camera options for a research lab for recording simultaneously from 3 or 4 cameras with enough quality to assess upper limb movements.
I would really appreciate if you could recommend me some cameras to that purpose and how to use them at the same time.  What should I buy? The cost could be medium
Thank you so much in advance

If you use high speed recording (>120) up to 3 cameras, I recommend a i9-9900 cpu or equivalent. However, during recording the cpu runs at about 80% load.
If more than 3 cameras are in use, I would recommend an Intel Core i9-13900K or similar in combination with a motherboard having the Z790 chip or similar. On these boards, there are at least 3 USB 3.1 ports available. In case of 4 cameras you may need an additional high speed 2-channel usb 3.0 or 3.1 interface card, connected to a PCI 4.0 x4 (x4 is important, not x1) slot on the board.
