Abstract

Systems and methods for creating a detector network across one or more existing communications systems. In one implementation, a system is provided. The system includes a plurality of hosts, each host hosting one or more detectors operable to detect an occurrence of an event, the hosts including functionality that is not related to the detectors and including communication functionality. The system also includes a management device for managing the detectors and one or more communications networks linking the detectors and the management device using the communication functionality of the respective host.

Claims

1. A method comprising:

receiving a first alert from a first detector of a plurality of detectors;

receiving a second alert from a second detector of the plurality of detectors the second detector being different from the first detector;

comparing a second alert type received from the second detector with a first alert type received from the first detector;

if the second alert type from the second detector is the same as the first alert type from the first detector, processing the alerts to determine a relationship between the alerts.

2. The method of claim 1, where the processing further comprises:

determining the spatial relationship between the first and second detectors.

3. The method of claim 2, further comprising:

determining a direction of travel for a source event generating the alerts.

4. The method of claim 3, further comprising:

determining a rate of travel for the source event using the spatial location of the first and second detectors and an elapsed time between the alerts.

5. The method of claim 1, where the processing further comprises:

providing instructions to the first and second detectors to provide video data associated with the time of the alert.

6. The method of claim 1, where the processing further comprises:

providing instructions to one or more detectors of the plurality of detectors, the instructions including placing the one or more detectors in a heightened state.
