Interactive surveillance network and method
First Claim
1. A module for operation in communication with a plurality of such modules forming an adaptive network thereof, each of the modules comprising:
- a unique identification code;
a transceiver disposed to transmit and receive data signals on a selected frequency of electromagnetic energy;
at least one sensor disposed to detect proximity of an object; and
a processor coupled to the transceiver and the sensor for forming a data signal representative of sensed proximity of an object for transmission with the identification code via the transceiver.

Abstract
A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of proximity of objects. A central computer accumulates the data produced or received and relayed by each module for analyzing proximity responses to transmit through the adaptive network control signals to a selectively-addressed module to respond to computer analyzes of the data accumulated from modules forming the adaptive network. Interactions of local processors in modules that sense an intrusion determine the location and path of movements of the intruding object and control cameras in the modules to retrieve video images of the intruding object. Multiple operational frequencies in adaptive networks permit expansions by additional networks that each operate at separate radio frequencies to avoid overlapping interaction. Additional modules may be introduced into operating networks without knowing the operating frequency at the time of introduction. New programs are distributed to all or selected modules under control of the base station.
