1. The industrial camera has stable and reliable performance, easy installation, compact camera structure, not easy to damage, long continuous working time, and can be used in harsh environments, which cannot be achieved by general digital cameras. For example, it is absolutely impossible to make a normal digital camera work 24 hours a day or several days in a row.
2. The shutter time of industrial cameras is very short, which can capture high-speed moving objects. For example, attaching a business card to a fan blade, spinning at maximum speed, setting an appropriate shutter time, and capturing an image with an industrial camera can still clearly distinguish the font on the business card. It is impossible to achieve the same effect with a normal camera.

3. The image sensor of the industrial camera is progressive scan, while the image sensor of the ordinary camera is interlaced. The production process of progressive scan image sensor is complex, the yield is low, and the shipment volume is low. There are only a handful of companies in the world. Products such as Dalsa, Sony and expensive are available.
4. The frame rate of industrial cameras is much higher than that of ordinary cameras. Industrial cameras can capture 10 to hundreds of images per second, while normal cameras can only capture 2-3 images, which is a big difference.
5. The output of industrial cameras is raw data, and its spectral range is often wide, which is more suitable for high-quality image processing algorithms, such as machine vision (MachineVision) applications. The images captured by ordinary cameras have a spectral range suitable only for human vision, and after mjpeg compression, the image quality is poor, which is not conducive to analysis and processing.
