Product Overview (Network Access Controller YHMJ):

Network access controller YHMJ is a real access controller based on TCP/IP network, which can control one-way access of four gates or two-way access of two gates. Using 32-bit ARM series as the main processing chip, RTOS real-time operating system and FAMS2 storage management system are run internally, and high-performance access control controller is designed according to the technical requirements of industrial level. YHMJ network access control controller not only has commonly used access control functions, such as offline operation, real-time monitoring, photo display, mass storage, flexible permission settings, remote opening, multi-user management, batch and a small number of fast settings, convenient query, report statistical format modification and printing output to Excel files, card + password, long-time open alarm, illegal card brush. Card alarm, head card opening, illegal intrusion alarm, regular opening, electronic map and other functions.

Network Access Controller YHMJ
