★ Efficient face recognition: The face recognition terminal uses Huawei Hisilicon's industrial-grade AI chip, embedded system, and HD wide dynamic AI camera lens, which can show superior performance in strong light, backlight, indoor and outdoor, Let students pass efficiently and orderly. Support card swipe, compatible with ID and IC cards
★ Time limit and time limit function: The system can set multiple time periods, and can set different permissions for entering and leaving the campus according to students, faculty, etc., which can prevent students from leaving the school during the class.
★ Stranger alarm function: When the face device detects a stranger, it will send a Mo Rensheng language alarm to remind the security personnel to pay attention.

★ Large screen statistics function: expandable TV, display real student data of each class
★ Large capacity: Face recognition terminal supports 20,000 students capacity
★ Batch import function: Supports batch import of student face library photos, greatly improving work efficiency.
Third, the introduction of smart campus WeChat push system platform
The smart campus face recognition system platform supports face swipe and card control, channel gate control management, real-time communication management, and real-time WeChat push management.
The smart campus platform is mainly divided into the following major modules to realize the needs of smart campus management.
System information module: management of system parameters, such as school information, database backup, push parameter settings, etc.
Facial equipment and authority management: Facial equipment login, communication, parameter settings, access control and management of students, faculty, etc.
Student management module: student file creation, modification, batch import, batch modification, class monitoring, parent binding, student permission assignment, etc.
Faculty management module: Faculty files creation, modification, import, authority allocation, etc.
Real-time monitoring module: it can display a large screen externally, real-time monitoring of the information of people entering and leaving the face, class entry and exit data monitoring.
Report and operation authority module: query in and out records, export and print, increase operator, and assign authority management.
