CT9 PRO Protects Digital Credentials

CT9 PRO serves as a smart reader staying outside, supporting multiple authentic credentials, including RFlD dual 125KHz & 13.56MHZ smart Cards, MIFARE Classic®, Mifare® Plus, DESFire®  EV1/EV2/EV3 smart cards. These support SAM AV2/AV3 encryption, ensuring high- security data exchange during credential verification. Even if someone breaks the CT9 PRO, the door remains locked since the real access decision happens safely inside with CN5.

CN5 Secures Electronic Lock Control

CN5 is a secure relay controller installed inside, managing the door lock control. It communicates with CT9 PRO via RS485, and makes the actual access decision. This physical isolation ensures tamper attempts at the reader do not impact the control logic.

Together, CT9 PRO and CN5 system offers a tamper-resistance access control solution that helps prevent forced entry and also strengthens security.
