ACAM-40 plus is a main controller produced by D&S Technology for access control system. Based on the information delivered from connected server, ACAM-40 plus verifies passers’ authentication on entry gate reader and controls the gate depending on the authentication result. Besides, it records and manages entry history of the gate and reports the result to the server. Also, ACAM-40 plus processes output by receiving the entry of surrounding sensor through I/O extension using entry 4 port, output 4 port and RS485.
