1、 Campus security has been gradually popularized in primary and secondary schools. At present, campus security is mainly composed of teaching office area and student learning and living area. Due to the difference of school area and students' age, the security system required by universities, primary and secondary schools is very different. Colleges and universities all over the country have high openness, miscellaneous personnel and large mobility, which increases the difficulty of campus security work; Although primary and secondary schools implement closed management, primary and secondary school students have relatively poor self-control and self-protection ability, so the video radiation area required by primary and secondary schools is larger. Therefore, the focus of security is different in primary and secondary schools. However, no matter how different its focus is, there is no doubt about its importance to the security of this group of protected people. Therefore, school monitoring is gradually moving towards the field of high-definition network video.

(1) Kindergartens: since the monitoring objects of their schools are protected weak children, it is more important to prevent external intrusion. Its extended application is mainly reflected in parents' remote viewing of kindergartens, including activities and classes;

(2) Primary and secondary schools: the school monitoring objects of primary and secondary schools are protected young people in development. Safety prevention is also one of the main purposes of school security, including not only external invasion, but also internal campus violence. Its extended application is more reflected in the application of electronic invigilator;

(3) Colleges and Universities: colleges and universities are basically adult people. It is important to prevent external intrusion and campus internal security, but the proportion of extended applications is increased, which is mainly reflected in the application of distance teaching.

2. Project analysis
(1) Video monitoring area: in order to ensure the normal work and life order of the school and the safety of the school, avoid the loss of school property, ensure the safety of teachers and students, and avoid illegal intrusion, it is necessary to effectively prevent the safety of the whole school. Through all-weather, real-time and high-definition video monitoring in many important areas and points such as library, school gate, playground, parking lot, School Road, square, perimeter, canteen and walkways on some floors.

(2) . point distribution requirements: the whole video monitoring requirements can meet all-weather local 24-hour monitoring. The front end must adopt the most advanced and stable camera at present. PTZ cameras or HD fixed cameras shall be used in important places such as school entrances and exits. HD ball cameras or HD gun cameras shall be installed in some wide public places such as school roads, playgrounds and canteens. Fixed HD cameras shall be installed in some areas such as school perimeter, and high-definition network hemispheres shall be installed in floor walkways.

(3) Alarm linkage: through the school monitoring management software and alarm interface software, the monitoring system can respond to the regional networked alarm system. After the user of the regional networked alarm system gives an alarm, the regional networked alarm host will automatically call the relevant images to the large screen or main monitor through the alarm interface software, and start the established plan system at the same time. The large screen of the main control center can display monitoring images, computer network information, GPS, GIS system and other information as a comprehensive display platform of various information.

(4) Network monitoring: through the school LAN, superior departments and relevant leaders can call any image, authorized users can call video data, etc.
