Features of USB industrial cameras

The characteristics of USB industrial cameras include the following:

1. 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 the 1394 camera needs to be connected to the computer alone. The 1394 capture card needs to be installed in it 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.

2. Stability

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 choice for most medium and low-speed industrial applications, which can greatly save user costs.

3. Cost advantage

As a 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.

4. Continuous upgradeability in the future

As the USB interface is widely used in the world, world-class associations are constantly promoting the upgrade of 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 a high-speed in the next 2-3 years. Main interface for industrial applications.

At the same time, with the continuous promotion and popularization of USB3.0 interface, USB industrial cameras will solve the problem of high-bandwidth transmission to achieve high frame rate, high resolution, and long-distance real-time processing, bringing industrial cameras to a higher-end stage.
