PC compatibility with QICam (QImaging) – cooled ccd camera:

This camera draws a significant amount of power from the computer to run. Newer PCs with built-in fire wire ports will not provide enough power to run the camera – which will result in software crashes and other frustrating and time-consuming troubleshooting. The fire wire card that comes with the camera must be installed to solve this problem.

Therefore if you are using the QICAM, a desktop computer is needed for this camera – with an empty slot for the card.
