Yes, TESA HOTEL has its own online wireless system. Not only do we have a real-time monitored electronic lock system, but also the locks are totally autonomous, battery-powered, with no need of wiring. Locks communicate with the PCs in the reception desk, where the management system is being executed, via the wireless hubs. This way, monitoring is complete and locks may be remotely opened, locked, left in pass-through mode and blocked; users can be deleted from them, shifts can be changed, etc. It is also possible to know whether they are open or locked, whether the battery is low, to receive alerts via e-mail or to monitor all related events in real time.
