In recent years, with the development of the Ministry of Education’s requirements for the construction of “fine classrooms” and the increasing application of objective structured clinical examinations, technologies such as information, network, and multimedia control have been widely used in audio-visual education, and the construction of recording and broadcasting systems has become a measure of school teaching One of the important evaluation indicators of quality, and as the starting point for the collection of video and audio images on the video platform, the choice of camera directly affects the construction quality and use effect of the teaching recording and broadcasting system.

Types of cameras

1. The camera is divided into two types: SD and HD. The physical resolution of standard-definition cameras is <720P, which is a display format that achieves a resolution of 1280x720 in progressive scan. The physical resolution of the HD camera must reach 1920x1080, which means that the horizontal resolution must reach 1920 pixels and the vertical resolution must reach 1080 scan lines. Internationally recognized high-definition video requirements are: video vertical resolution> 720P or 1080i, video aspect ratio 16:9, wide color gamut, large screen and surround sound broadcasting can be used, which has stronger appeal and visibility.

2. The high-definition camera has the advantages of high resolution, large horizontal field of view, and many inclusive scenes. If a recording system with a wider coverage is to be built, only the high-definition camera can meet the application requirements of high-level courseware quality. However, there are many similar products on the market, and the prices vary. Therefore, if you want to choose a suitable camera, you need to comprehensively test the camera's resolution, color reproduction ability, and aggregation ability before the project plan is determined.
