When does it make sense to switch to a new camera interface like USB 3.0 (USB3 Vision)?
Switching from one camera interface to another always involves some integration effort within the system. This effort will pay off, if following criteria are met:
The hardware of the camera interface in use is gradually becoming more expensive and harder to obtain, as is currently the case with FireWire.
The bandwidth cannot meet the requirements of modern vision systems anymore (higher frame rates, higher resolution, or another image format). This, for example, applies to FireWire (IEEE1394b: max. 64MB/s) and USB 2.0 (max. 40MB/s).
Savings due to reduced manufacturing costs usually justify this one-time integration effort. This might apply when changing from FireWire or from frame grabber-based interfaces such as “analog” or “Camera Link base”.
