VisorALARM receiver over IP

February 2007 IT infrastructure

The VisorALARM IP receiver is a communications device developed by Teldat for the area of security and whose task is to receive alarms over an IP network and send them to an automation software.

The difference between traditional receivers, which receive alarms over the telephone network and resend them to the automation software through a serial port, is that the VisorALARM receives the alarms over IP. The said alarms are encrypted with a session key in order to resend them, after they have been decoded, to the automation software in the same way as a traditional receiver sends received alarms through a serial port.

A VisorALARM can emulate a Sur-Gard receiver or a Radionics 6500 receiver or an Ademco 685 receiver as the serial line parameters as well as those relative to the emulated receiver (link-test, receiver and line identifiers, frame beginning and end characters, etc) are configurable. Thanks to the network backup functionality, a second VisorALARM configured as backup has been added. This converts into a second option for sending alarms in cases where the main VisorALARM fails. Should the polling carried out over the main device fail then the mIP establishes communications with the backup VisorALARM. The mIP continues to poll the backup and sends any alarms that have been produced and also carries on polling the main device until it is accessible once more. At this point the mIP returns from backup and re-establishes communications with the main VisorALARM.
