ZKTeco SRB Security Relay Box
The Security Relay Box (SRB) is a value-added and cost-effective single-door controller to enhance access control in a simple and secure way. Designed to provide an added layer of security when connected to ZKteco standalone readers. SRB (not the reader) controls the door lock, thus preventing unauthorized parties from bypassing the door lock when tampering with the reader.
