At present, from the introduction of the government's normative opinions, to the formulation and mandatory implementation of local standards, campus security construction has been widely concerned by all sectors of society, and technical defense has become an important means of campus security, and cooperate with civil air defense and physical defense to create a safe campus。

At present, whether it is an ordinary university or a primary and secondary school, the current situation of campus security is not optimistic, basically in a situation dominated by civil air defense and machine defense, and technical defense is still in its infancy。The school continues to increase investment in civil air defense and machine defense, such as increasing school security personnel, organizing school guards by students, raising walls, and installing steel bars on the Windows of student dormitories。 These measures have a certain effect, but there are also some drawbacks, such as the school guard will bring continuous expenditure, and the installation of steel guardrail in the dormitory does not meet the fire protection requirements。
Campus security is mainly composed of two parts: one is the teaching office area, and the other is the area where students study and live。At present, most primary and secondary schools are closed management, but the students' self-control is relatively poor, self-protection ability is also weak 。Therefore, from the analysis of the environment, campus security has the characteristics of more monitoring points and large monitoring area。
