FireWire® or IEEE 1394
FireWire cameras (also known as IEEE 1394 cameras) have been on the market for many years and are implemented in thousands of applications. Initially, the cameras adhered to the FireWire-a standard. This meant that they had a bandwidth limitation of 32 MB/s and that only about one megapixel resolution at about 30 frames per second could be transmitted smoothly. Today’s FireWire-b interface provides twice this bandwidth. Cabling and hardware are standardized and widely used, making FireWire a cost effective solution in many cases.
One main advantage of FireWire lies within the FireWire standard itself. The standard defines a very stable method for exchanging data between the cameras and the computer. This ensures a reliable transmission sequence, as well as a reliable receive sequence and a predictable data transfer duration.
For FireWire cameras compliant with the DCAM/IIDC standard, a logical interface for industrial cameras is well defined. This facilitates easy integration into image processing software as well as simultaneous operation of cameras from different manufacturers or even an exchange of cameras.
Some of the advantages of the FireWire interface are:
- Standard logical interface available
- Easy system integration
- Very low CPU load
