We instantly modernize your existing legacy access readers

The Zerver B is installed between the existing door reader and the physical access control system. Digital credentials are sent from a mobile device or wearable to the Zerver B device using Bluetooth Low Energy (802.15.4). The Zerver B decrypts the secure digital credential and sends it to the control panel using industry standard Wiegand or RS485. The physical access control system authorizes the request for access and triggers an LED and audible response on the host reader.

Access Installation

The Zerver B is powered from the host controller. By connecting one side of the Zerver B directly to the control panel and the other side of the Zerver B device directly to the reader, Mobile access through the Zerv software is enabled. A full wiring diagram can be found in the Install Guide which includes dimensions, antenna instructions, wiring instructions and power-up steps.
