Fingerprint & Card • RS485 Sync • Secure Exit Control
The Ultimate Secondary Verification for Secure Exit
Standard access control systems often secure only the entry point, using a simple push button for exiting. However, for facilities requiring total audit trails, the eSSL F12 Biometric Slave Reader is essential. This is not a standalone machine; it is a dedicated “slave” reader designed to work in tandem with a Master Controller (such as the F18, F22, or inBio panels). By installing the F12 on the inside of a door, you require employees to verify their fingerprint or RFID card to exit, as well as to enter. This creates a foolproof log of exactly how long a person remained inside a room. It features a high-performance optical sensor and connects back to the master unit via a stable RS485 interface. Housed in a slim, space-saving chassis, it ensures that your high-security areas like server rooms, cash vaults, and R&D labs have an unshakeable biometric record of all movement.
👆 Dual Verification Slave
👁️ Optical Fingerprint Sensor: Utilizes eSSL’s renowned biometric algorithm to provide rapid matching when connected to a master controller.
💳 RFID Card Reader: Integrated 125KHz proximity reader allows for card-based exit, providing flexibility for staff with unreadable fingerprints.
🔔 Visual & Audio Feedback: Equipped with a multi-color LED and beeper to let the user know their exit verification was successful.
⚙️ Architecture & Sync
🔌 RS485 Communication: The industry-standard interface for slave-to-master data transmission, ensuring that fingerprint templates are processed by the main controller securely.
🏗️ Master-Slave Logic: The F12 does not store data locally; it pushes the scan to the master unit (e.g., F18) for decision making, ensuring that even if the slave is tampered with, the door remains locked.
🛠️ The BuyCCTVs.com Advantage – Complete Your Setup
At BuyCCTVs.com, we provide the master components required to make the F12 operational:
🖥️ Master Controllers: Pair the F12 with our eSSL F18 or F22 biometric terminals to enable two-way secure access.
🏗️ inBio Control Panels: For multi-door enterprise setups, wire the F12 into our inBio 260 or 460 master panels.
🔌 Specialized Wiring: Ensure stable RS485 communication by using our premium shielded twisted-pair cabling.
🔍 Deployment Logic
This is a Biometric Slave Reader. It cannot work alone.
Strategic Placement: Mount the F12 on the internal wall next to a high-security door. Its slim profile makes it perfect for narrow door frames where a full-sized attendance machine would not fit.
🏢 Why This Reader is Essential?
Anti-passback and complete audit trails are only possible with slave readers.
🧪 R&D Labs: Ensure only the authorized scientist who entered the lab is the one who leaves, maintaining strict safety protocols.
🏦 Bank Vaults & Cash Rooms: Mandatory for high-stakes areas where a record of “time spent inside” is a legal or insurance requirement.
