# 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](https://www.amazon.com/dp/B0BH252R3J)

## Cameras
Here I list some of the cameras as an example of cameras that fit the criteria mentioned in the [camera selection guide](camera-selection-guide.md). I am not affiliated with the manufacturers mentioned. There may be cameras with specs more ideal for your setup.

| Camera | Sensor | Shutter | Resolution | FPS | Field of View | Interface | Recommended Budget |
|--------|--------|---------|------------|-----|---------------|-----------|--------------------|
| [Arducam 800P Monochrome Global Shutter USB Camera](https://www.amazon.com/dp/B0FXWWF55X) | OmniVision OV9281 (mono) | Global | 1280 × 800 | 120 (MJPEG) | 130° (M12 lens) | USB 2.0 | $200 |
| [ELP 1080P Global Shutter USB Camera, 120° lens](https://www.amazon.com/dp/B0C3C2YVK9) | onsemi AR0234 (color) | Global | 1920 × 1200 | 90 (MJPEG) | ~126° horizontal (low distortion) | USB 2.0 | $500 |
| [ELP 5MP Global Shutter USB3.0 Camera, 120° lens](https://www.amazon.com/dp/B0H4KPRV1X) | OmniVision OG05B10 (color) | Global | 2592 × 1944 | 60 (MJPEG) | ~126° horizontal (low distortion) | USB 3.0 | $1000 |

```{note}
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.
