THE ULTIMATE ACCESS CONTROL SYSTEM HWg-SH4 HW group

The SH4 is an ultimate access system that works with any electromagnetic lock and any RFID reader. It will work in your datacenter as well as in your office or even your home. Whether you have one door or several hundred racks, the SH4 system provides a cost effective way to manage access to your technology.

In offline mode the SH4 can work as a standalone device that holds an internal database of cards and users.
 
You just need the Ethernet port to setup the unit and the device will follow the access rules without the need for LAN connection.
 
 
In online mode the device is connected with a server running the HWg-DCD software. This server manages all the access rules.
 
The relevant part of the entire user database is loaded in each SH4 so that you can still access your technology even if your network connectivity fails.
