The Guard series of products (Meeting Guards and Room Guard) is designed to provide a 24 hour / 7 day a week solution for monitoring the RF spectrum between near DC to 10GHz. If a signal is detected that is above the thresholds set by the operator, then an Alarm will appear on the control panel. The panel is configured as below:
The control panel comprises of a “radar” icon to show the unit is scanning and dedicated detector icons looking at specific signals. We interpret those signals in software and correlate to the six icons (Now there could be an instance where a mobile phone triggers an event and because it is not in our database the wrong icon is activated). The icons are:
2) Wireless Camera (2.4Ghz)
3) Unidentified RF signal
4) Cellular Phone
6) Dect Phone
The user can set the thresholds on each icon to minimise false alarms. Alarms are generated in two stages. If the signal is higher than the first threshold but lower than the Alarm level then the Radar screen will go yellow along with the suggested icon and give a “RISK” warning. In the example below it is expected the signal is a mobile phone.
If the signal is higher than the Alarm threshold, then the radar will go red along with the suggested icon.
Unidentified RF signal
The software can be put on a PC/Laptop and this can either talk directly to the RoomGuard unit or the RoomGuard unit can be added directly to the Network (configured appropriately) and a PC/Laptop also on the network and with the software installed can then be used to monitor / control the unit.
The user controls are password protected to only allow an authorised person to set the alarm levels etc.
Finally all the Alarms are logged and are easily retrievable by the user.
Where a customer has multiple buildings or a large volume of rooms to monitor then a more expansive system can be procured. An example is detailed below.
In this scenario, extra expense is incurred in the server, additional storage space and the software required on the server (procured from Microsoft). The software is then configured for the end user. This can be negotiable if we have developed it already for another customer. The Buildings talk to the control centre utilising Virtual Private Networks (VPN), this allows for an extremely secure, flexible and configurable system. The system could be upgraded to Scanlock M5 hardware which then allows for real time recording of the RF network and files to be downloaded and passed back to Audiotel for further analysis if required (i.e. actual demodulation of signals or database enhancement).
In effect the control software can be made to meet the customer requirements. Our plan for one customer is to have up to 100 units monitored by one user with a simplistic overview of the 100 units in either a green, yellow or red state and then allow the customer to interrogate the individual unit when an alarm is generated. This could be achieved by the additional analysis machine while the operator continues to monitor the 100 units.
