HWg-SH4e

The small applications can be for example apartment houses, small companies, or systems using existing RFID tags.

Apartment building access system

HWg-SH4 can be used as an access system for apartment houses or offices. A typical application can be using RFID reader for access from the outside of the building, together with an exit button installed on the inner side of the door. To enter the house you can then simply use the RFID tag and to leave the building you can press an exit button. The door can be also opened remotely from individual apartments. The system can also be used to control the gate to a parking lot.

Using HWg-DCD is in such cases is optional, as it is not needed for direct administration. However it can notably simplify registering of access tags and deactivation of the lost ones.

Access into a company building with a gate

HWg-SH4 can be used for entry gates on company parking lots. One RFID reader with a keyboard would control the entry gate and another reader with a keyboard would then control access into the building (the gate and the door require differend codes assigned). An exit button can be used for leaving; eventually a second RFID reader can be used at the gate (can be then used for evidence of cars parked in the parking lot). Using the HWg-DCD is optional here as well.

Building access system with availability for other applications

Thanks to the ability to use common RFID readers the HWg-SH4 is optimal for integration into existing systems. For instance in many schools and libraries there are some RFID tags systems already installed.

With HWg-SH4 you can easily assign access rights to a building by using the same tags. Also late arrivals are then recorded, the log can also be sent as e-mail or SMS notifications. The same can be applied in different office or storage premises.

Using HWg-SH4 in IT environment

Standalone solution for racks

A typical application for HWg-SH4 is in a rack cabinet, not only in individual cabinets but also as a part of a data center. HWg-SH4 unit is then installed inside the rack and the RFID reader is placed on one of the doors (or both). If there is only a single HWg-SH4, it can be simply configured in offline mode through its WWW interface. However if HWg-SH4 is installed in a data center where one unit is installed in every cabinet, it is recommended to use the devices in online mode with HWg-DCD.

A solution using remote HWg-SH4e/HWg-SH4s units One of the main advantages of the HWg-SH4 system is the option to use one control unit with several subordinated HWg-SH4e or HWg-SH4s units. In such cases a use of RFID reader with a keyboard connected to HWg-SH4 is expected. Individual doors have their own unique numbers corresponding with a door (key/lock) number or with a number of the rack cabinet (where the number is then used as a door code). Subordinated units HWg-SH4s or HWg-SH4e, which directly control the door locks, are installed in individual rack cabinets.

NOTE: The units (both head and subordinated) can also use relay type objects for example for lighting control in racks or for identification of the unlocked door. This function is not active in default.
