The school monitoring system is mainly divided into four parts: front-end image acquisition system, transmission system, storage system and display system. Any monitoring system is inseparable from these four parts, so let's start with the front-end image acquisition system.

Whether the arrangement of front-end points in the design of school monitoring system is reasonable and whether the equipment used is appropriate are the key of the whole system. Therefore, in this design, all front-end points adopt high-definition network cameras. Because the elevator cannot arrange network cables, special analog cameras for elevator are adopted. Each elevator camera is equipped with a single network video server to access the video monitoring network after analog-to-digital conversion.

1. School gate, playground, School Road, square, etc.: infrared high-definition high-speed ball is installed in school gate, playground, School Road, square and other places because the light is dark and broad at night.

2. Library, canteen and other areas: these areas are relatively large and crowded, so indoor network HD ball camera is adopted.

3. School Road, perimeter, school gate and other areas: install HD network cameras in these places.

4. Floor walkways and other areas: install HD network dome cameras in these places.

5. Elevator: hemispherical elevator special camera is adopted.

6. Other areas: appropriate camera type shall be adopted according to the specific situation of the site.

When determining the point position, reasonably arrange the installation position of the camera according to the planning of the monitoring area, and try to meet the principles of no blind area monitoring in key areas and considering other areas.
