Ordinary people can also have video and audio conversations and communicate with each other on the Internet through the camera. In addition, people can also use it for various popular digital images, audio-visual processing and so on.
Cameras can be divided into digital cameras and analog cameras. Digital cameras can convert analog video signals generated by video acquisition equipment into digital signals, and then store them in computers. The video signal captured by analog camera must be converted into digital mode by special video acquisition card and compressed before it can be converted into computer. Digital camera can shoot images directly, and then transmit them to computer through serial port, parallel port or USB interface. The cameras in the computer market are mainly digital cameras, and digital cameras are mainly USB digital cameras with new data transmission interfaces, which are mostly visible in the market. In addition, there is another product that works with the video capture card, but it is not the mainstream. Due to the rapid popularization of personal computers, the overall cost of analog cameras is high, and it can not meet the interface of BSV LCD splicing screen. The transmission speed of USB interface is much higher than that of serial port and parallel port, so there are digital cameras with USB interface on the market. Analog camera can be used with video capture card or USB video capture card, which is convenient to connect with computer. The typical application is general video surveillance. Clean area camera, clean area embedded special camera is a special camera for real-time monitoring of key parts of important equipment in clean room.
The camera plate is embedded with color steel plate, with zero sanitary dead angle, convenient cleaning and installation, fast multi-point control and compatibility with mainstream cameras (network cameras). Generally speaking, webcams have basic functions such as video shooting/transmission and still image shooting. After the image is collected by the lens, the photosensitive element circuit and control element in the camera process the image and convert it into a digital signal that can be recognized by the computer. Then input it to the computer through parallel port or USB connection, and then the software camera (camera or network camera) is also called computer camera, computer eye, electronic eye and so on. It is a video input device, which is widely used in video conferencing, telemedicine and real-time monitoring.
The video signal is converted into a digital signal and then stored in the computer. Captured the analog camera
