Abstract

According to another embodiment, a method of detecting the occurrence of a condition using a detection system located within a predetermined area includes transmitting light from at least one node of a plurality of nodes into an ambient atmosphere adjacent the at least one node, receiving scattered light from the ambient atmosphere at the at least one node, communicating the received scattered light to a control system operably coupled to the at least one node, analyzing the scattered light at the control system to determine a condition of the ambient atmosphere adjacent each at least one node, and adjusting a sensitivity of the at least one node of the plurality of nodes.

Claims (26)

1. A method of detecting the occurrence of a condition using a detection system located within a predetermined area comprising:

transmitting light from at least one node of a plurality of nodes into an ambient atmosphere adjacent the at least one node;

receiving scattered light from the ambient atmosphere at the at least one node;

communicating the received scattered light to a control system operably coupled to the at least one node;

analyzing the scattered light at the control system to determine a condition of the ambient atmosphere adjacent each at least one node; and

adjusting a sensitivity of the at least one node of the plurality of nodes, wherein adjusting the sensitivity of the at least one node further comprises determining a region of the predetermined area within which the at least one node is located and determining a risk associated with the region of the at least one node.

2. The method of claim 1 , wherein the risk associated with the region of the at least one node is determined based upon at least one of a risk of occurrence of a condition, traffic flow within the region, assets located within the region, environmental nuisances, and access to an environment within the region.

3. The method of claim 1 , wherein adjusting the sensitivity of the at least one node comprises altering one or more parameters associated with analyzing the scattered light.

4. The method of claim 3 , wherein the one or more parameters comprises one or more of a time of day, a day of week, a day of month, and a day or year.

5. The method of claim 3 , wherein the one or more parameters comprises a condition detected at another node of the plurality of nodes.

6. The method of claim 2 , wherein adjusting the sensitivity of the at least one node further comprises determining an operational status of the at least one node using the control system.

7. The method of claim 6 , wherein determining an operational status of the at least one node comprises analyzing background data collected by the control system.

8. The method of claim 6 , wherein adjusting a sensitivity of the at least one node occurs in response to determining the operational status of each of the plurality of nodes.

9. A method of detecting the occurrence of a condition using a detection system located within a predetermined area comprising:

transmitting light from at least one node of a plurality of nodes into an ambient atmosphere adjacent the at least one node;

receiving scattered light from the ambient atmosphere at the at least one node;

communicating the scattered light to a control system operably coupled to the at least one node;

analyzing the scattered light using an algorithm to evaluate a condition of the ambient atmosphere adjacent the at least one node; and

displaying on a display a status of the predetermined area in response to information provided by at least one node of the control system and an input, wherein the input is provided separately from the information provided by the at least one node of the control system.

10. The method of claim 9 , wherein displaying a status of the predetermined area comprises displaying a map of the predetermined area, a location of the at least one node, and a location where the condition was detected.

11. The method of claim 10 , wherein displaying the location where the condition was detected comprises identifying a node where the condition was detected.

12. The method of claim 9 , wherein the at least one input is received by a user interface.

13. The method of claim 12 , wherein the at least one input comprises a command to adjust one or more parameters associated with the control system.

14. The method of claim 12 , wherein the at least one input comprises authorization credentials.

15. The method of claim 12 , wherein displaying a status of the predetermined area further comprises displaying information about a status of a node comprising a blocked node or non-functioning node.

16. The method of claim 12 , further comprising displaying on the display one or more algorithm parameters associated with the control system.
