USB industrial camera interface and 1394 industrial camera interface are two commonly used interfaces in industrial cameras. Although the interfaces of these two industrial cameras are not very different, they have different differences when it comes to the application of machine vision.
There are more than 50 industrial specification protocols related to 1394 equipment, involving cameras, industrial cameras, and other equipment. Most of the 1394 industrial cameras from various manufacturers follow the DCAM industry specifications. The USB industrial camera interface is a commercial specification recently developed from commercial PC applications.
1394 interface industrial cameras can keep their original addresses unchanged after the system is restarted, while USB interface industrial cameras require the system to re-allocate addresses every time they are started.
The operating voltage of 1394 industrial camera is 8 to 30VDC, and the operating voltage of USB industrial camera is 5VDC. From the perspective of power supply range, the 1394 interface meets the DC power supply requirements of individual equipment in the industrial field, such as 12VDC or 24VDC; while the USB interface uses the TTL standard voltage power supply of electronic circuits and is generally used for internal power supply of equipment.
The 1394 interface has inherent advantages when processing data transmission from multiple industrial cameras. From the perspective of development background, the USB interface is a new generation of high-speed data transmission interface that accepts the RS232 interface, while the 1394 interface industrial camera is designed to replace the SCSI and PCI buses.
The above is the relevant introduction to the difference between USB industrial cameras and 1394 interface industrial cameras.
