What is the Difference Between a USB Interface Industrial Camera and a 1394 Interface Industrial Camera?
The main factors that affect our choice of USB camera and 1394 camera in terms of interface are as follows:
1). Protocol specifications: There are more than 50 industrial specifications related to 1394 equipment, involving cameras, industrial cameras, and other equipment. Most of the 1394 industrial cameras from various manufacturers follow the DCAM industrial specification. The USB industrial camera interface is a recent commercial specification developed from commercial PC applications.
2). Power supply mode: 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 electronic circuit TTL standard voltage power supply, which is generally used for the internal power supply of the equipment.
3). Operating system coordination: The 1394 interface industrial camera can keep the original address unchanged after the system is restarted, while the USB interface industrial camera needs to be re-assigned by the system after each startup.
4). Data transmission: 1394 interface has inherent advantages when dealing with data transmission of multiple industrial cameras. From the development background, the USB interface is a new generation of high-speed data transmission interface to undertake the RS232 interface, and the industrial camera of the 1394 interface is designed as a substitute for SCSI and PCI bus.
