In general, what camera to choose depends on the specific use case, for example, should a video conference ingest the entire venue? Do you want to keep track of speakers? What is the size of the meeting room? Do you want to hang it or put it on the table? After determining these basic needs, compare price, appearance, performance parameters, etc. You can also refer to the video conference USB camera from the parameters below.

The lens is an important part of the camera. The sensor of the camera can be divided into CCD and CMOS. CCD is a high-end technical component used in photography and cameras. CMOS is used in products with lower image quality. The advantage is that the manufacturing cost is much lower than that of CCD, and the power consumption is much lower than that of CCD, which is the reason why many products using USB interface on the market do not need external power supply. At present, the size of CCD element is mainly 1/3 or 1/4 inch. For the same resolution, it is better to choose larger components.

The pixel value is an important indicator that affects the quality of the camera, and it is also an important indicator to judge its advantages and disadvantages. At present, the pixel value of mainstream products is generally around 2 million. It is also unnecessary to blindly consider pixel values. Because the higher the pixel value, the better the ability to analyze the image. In this way, when the camera is working, the data processing capacity of the computer is also high, otherwise it will cause image delay, thereby affecting the transmission of the video conference.

Resolution is the ability of a camera to analyze and recognize images. Of course, it is directly related to the quality of the CCD/CMOS. Generally, it can be divided into photo analysis and video analysis, that is, the resolution of static image capture and dynamic image capture. In practical applications of video conferencing, image analysis is usually higher than video analysis. There are also different types of resolutions that cameras on the market can give, so you should pay attention when buying, some resolution marks refer to the resolutions that these products can achieve using software, but there is still a certain gap with the hardware resolution.
