Four major features of USB industrial cameras

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 USB interface drivers is much lower than that of 1394 and GigE interface drivers. Therefore, the price of USB industrial cameras is not only cheaper than the original analog camera with analog capture card, but also cheaper than cameras with 1394 and GigE interfaces. The overall cost of USB industrial cameras is 15%-30% lower than other digital cameras.

The characteristics of USB industrial cameras include the following:

1. Stability USB industrial cameras are very suitable for use with one computer and 1-2 cameras, and their stability is very good. USB industrial cameras are the best choice for most medium and low-speed industrial applications, which can greatly save user costs.
2. Ease of use 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, and there is no need to prepare a separate power supply for the camera, while GigE cameras require an independent power supply to power the camera alone. Therefore, the ease of use of USB industrial cameras is the best among the three digital cameras.
3. The USB interface will continue to be upgraded in the future. As the most widely used interface in the world, world-class associations are constantly promoting the upgraded 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 are now available. 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. In the next 2-3 years, it will become the primary interface for high-speed industrial use.
4. Cost advantage: 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 USB interface drivers is much lower than that of 1394 and GigE interface drivers. Therefore, the price of USB industrial cameras is not only cheaper than the original analog camera with analog capture card, but also cheaper than cameras with 1394 and GigE interfaces. The overall cost of a USB industrial camera (the camera itself and supporting cables) is 15%-30% lower than other digital cameras. At the same time, as the USB3.0 interface continues to be popularized, USB industrial cameras will solve high-bandwidth transmission to achieve high frame rate, high resolution, and long-distance real-time processing, bringing industrial cameras to a higher-end stage.
