As the most widely used interface in the world, the USB interface has extremely cheap interface driver chips and driver circuits. The cost of a camera mainly consists of three parts: imaging chip and circuit, interface driver chip and circuit, and casing. The cost of the USB interface driver is much lower than that of the 1394 and GigE interface drivers. Therefore, the price of the USB industrial camera is not only cheaper than the original analog camera with an analog capture card, but also cheaper than the camera with the 1394 and GigE interface. The overall cost of USB industrial cameras (the camera itself and supporting cables) is 15%-30% lower than other digital cameras.
USB interface is the most widely used interface in the world. Various computers come with 2-4 USB interfaces. USB industrial cameras can be directly connected to the USB interfaces of these computers to work stably, while 1394 cameras require a separate 1394 capture card to be installed in the computer to work. In addition, the USB interface can directly power USB industrial cameras without the need to prepare a separate power supply for the camera, while GigE cameras require an independent power supply to power the camera separately. Therefore, the ease of use of USB industrial cameras is the best among the three digital cameras.
As the most widely used interface in the world, USB interface is continuously promoted by world-class associations to upgrade the USB interface protocol. USB3.0 is becoming the standard interface for the new generation of computers and electronic products. At present, USB3.0 industrial cameras have come out. The transmission speed is 5X higher than USB2.0, reaching 2.5Gbit/s, which is 3 times the 1394B transmission speed and 2.5 times the GigE transmission speed. It will become the main interface for high-speed industrial applications in the next 2-3 years.
USB industrial cameras are very suitable for applications where one computer is equipped with 1-2 cameras, and the stability is very good. USB industrial cameras are the best choice for most medium and low-speed industrial applications and can greatly save user costs.
