Abstract

A security system (52) using cellular wireless half duplex communication call (62) is provided. The security system (52) comprises a set of monitored resources (10), group of owners (48) and group of helpers (50) connected using said cellular wireless half duplex call (52). The monitored resource (10) is configured to generate an alarm and is coupled with said cellular wireless half duplex call (62). Said owners (48) and helpers (50) are also coupled with said cellular wireless half duplex call (62). In an event of emergency said monitored resource (10) generates an alarm and initiates said cellular wireless half duplex call (62) to connect to said owners (48) and said helpers (50) in shortest possible time without significantly contributing to cellular network load. Said security system (52) provides most scalable, efficient and viable security solution using cellular wireless networks.
