The Zerver B makes it easy to upgrade any existing access control system with mobile access, without giving up support for your physical access cards. When connected between a host reader and a physical access control panel, the Zerver B enables mobile devices and wearables to be used as a replacement or in conjunction with existing card technologies
* Our Smart Locks Connect to any mobile device via Bluetooth Low Energy (BLE) or WiFi (RF)
Streamline end-user experience with a single credentials
Consolidate all your credentials into one secure, convenient location in the Zerv software.
Keep using existing cards and badges
Mobile credential management eliminates costs associated with deployment and re issuance of traditional physical access cards.
Activation range can be configured based on environmental requirements. Where an additional range is required, the Zerver B supports the use of external antennas for both the BLE and optional Wi-Fi interfaces.
Multiple I/O Interfaces
Includes 5v input/output trigger, internal/external antennas, Wiegand, RS-485, and Wi-Fi module
OTA (Over-the-air configuration)
Firmware updates and configuration management can be made over-the-air through the Zerv software or Wi-Fi module.
IoT and Smart Building Data Analytics
Standards based MQTT interface enables high volume IoT data to be sent from supported devices to an authorized broker
Migrate to digital credentials at your own pace
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
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.
