Hardware Considerations¶
USB hubs¶
In many-camera setups, you may find yourself running out of USB ports. USB hubs allow you to connect many cameras into a single port on your computer. In that case, make sure to select an externally powered USB hub, as a plain hub is likely unable to provide enough power for all your cameras
Example: Wenter 11-port powered USB 3.0 hub
Cameras¶
Here I list some of the cameras as an example of cameras that fit the criteria mentioned in the camera selection guide. I am not affiliated with the manufacturers mentioned. There may be cameras with specs more ideal for your setup.

注釈
Specs are taken from the manufacturers' listings. Frame rates are only reached with compressed (MJPEG) output; uncompressed (YUY2) output is much slower over USB 2.0.
Computer hardware¶
There are no strict hardware restrictions and mocap FPS depends on the model used, but an Nvidia RTX graphics card (RTX 20xx or higher) is recommended for best performance.
