The analysis is as follows:
Yes, some cameras now have audio receivers. For example, several models of Hikvision have audio receivers. Although Hikvision is not a professional camera, it can also be brought. Here is a camera with audio input made by a company in Shenzhen, although it is not a brand. But it can realize your basic function

1. CAMERA or WEBCAM, also known as computer camera, computer eye, electronic eye, etc., is a video input device, which is widely used in video conferencing, telemedicine and real-time monitoring.
2. Ordinary people can also have video and audio conversations and communication with each other through the camera. In addition, people can also use it for various popular digital images, audio-visual processing and so on.
3. Cameras can be divided into digital cameras and analog cameras. Digital camera can convert analog video signals generated by video acquisition equipment into digital signals, and then store them in computer. The video signal captured by the analog camera must be converted into digital mode by a special video capture card and compressed before it can be converted to the computer for use. Digital camera can capture images directly, and then transmit them to the computer through serial port, parallel port or USB interface.
4. Digital cameras are the main cameras in the computer market, and USB digital cameras with new data transmission interfaces are the main digital cameras, and most of them are visible in the market. In addition, there is a product that works with video capture card, but it is not the mainstream.
5. Due to the rapid popularization of personal computers, the overall cost of analog cameras is high, and the interface of BSV LCD splicing screen cannot be met. The transmission speed of USB interface is much higher than that of serial port and parallel port, so digital cameras with USB interface are 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.
6, clean area camera, clean area embedded dedicated camera is a dedicated camera for real-time monitoring of key positions of important equipment in clean area clean room. The camera has a flat panel, embedded with color steel plate, zero sanitary dead angle, convenient cleaning and installation, and can be quickly and multipoint controlled, which is compatible with mainstream video systems.
7. webcam generally has the basic functions of video shooting/transmission and still image capture. After the image is collected by the lens, the image is processed by the photosensitive component circuit and control component in the camera and converted into a digital signal that can be recognized by the computer, and then input to the computer through the parallel port or USB connection, and then the image is restored by the software.
