A data sensing and threat detecting network comprising a plurality of wireless sensor devices for communication with wireless detector units in a multi-hop arrangement to allow transmission of data there between in optimized paths. The network further has a plurality of low power sub-sensor devices for transmission of data to respective sensor devices in close proximity thereto due to their low power, but their low cost allows them to be used in large numbers to blanket substantially all of the physical space in a venue. The sensor and sub-sensor devices may include portable sensor devices and condition sensing devices. |
