Comparing USB 2.0 to FireWire.
Video performance in digital cameras is defined by the maximum frame rate, at any given resolution and is measured in frames per second (fps). Both FireWire and high-speed USB 2.0 digital cameras, exhibit almost identical frame rates by resolution.
These frame rates are usually in fact limited by the sensor read-out rates ó not the physical hardware interface.
As an example, a 1 megapixel CCD sensor using a FireWire or USB 2.0 interface is limited to 15 or 30 fps depending on
the camera model. As resolution increases, frame rates decrease.
USB 2.0 is an ideal interface for scientific cameras, offering plug-and -play with all computers, while providing more than enough throughput for itís selected image sensors.
USB 2.0 480 MBIT/S 15 FPS PLUG-AND-PLAY, 99% OF Computers have USB 2.0 Ports, including laptops.
Firewire 400 MBIT/S 15 FPS Most computers require that a firwire card be installed. Some laptops may not have the ability to fit a firewire card.
