Abstract

A security system with processing optimized for monitoring the actions of a surveillance subject and detecting abnormal actions. The action record of an individual is monitored using a sensor network security system SNS, and the development of an action event is reported as an action, and the corresponding processing of the security system SCS is determined based on this action.

Claims

1. A security system including:

a device installed at a site,

a control device for controlling a state of the device, and

a management device for specifying the device to control a state according to any one of a plurality of preset security levels,

wherein the management device can connect to a first server via a network,

the first server contains a function for detecting whether information collected from multiple nodes installed within a site matches conditions registered beforehand, and

the management device registers conditions beforehand in the first server when there is a change in the security level, and receives notification from the first server that there is a match to the conditions, so that changes in the security level can be made to match the conditions.

2. A security system according to claim 1, including:

a first server connected via a network to a second server,

a second server for storing information collected from multiple nodes,

wherein the first server is capable of accessing information stored in the second server by storing storage destination information showing the storage destination of the information, and the first server or the second server detects matching conditions.

3. A security system according to claim 1, wherein the state of multiple nodes installed within a site are identified according to the security level, and when the first server detects a matching condition, the multiple nodes are controlled so that the security level is changed according to the corresponding condition.

4. A security system according to claim 1, wherein the multiple nodes include node attachable to a person, and the condition is that changes over time in the actions of a person collected from the attachable nodes, are excluded from the range allowed in the pre-registered personal information.

5. A security system according to claim 1, further including a sensing device within the site, and the control device identifies an error based on information from the sensing device.

6. A security system according to claim 5, wherein the first server collects information from the sensing device for use in judging the registered conditions.

7. A security system according to claim 1, including a surveillance camera as the sensing device, wherein the method for controlling the surveillance camera is changed according to the security level.

8. A method for managing a site, comprising:

controlling states of devices installed in the site to a state according to any one of a plurality of preset security levels,

setting conditions beforehand in a first server for changing a security level,

receiving notification from the first server that information collected from multiple nodes installed in the site matches preset conditions, and

controlling the state of one of the devices so that changes in the security level are made according to the matched preset conditions.

9. A method for managing a site according to claim 8, wherein a second server collects information from multiple nodes, and the first server or the second server detects a match with the preset conditions.

10. A method for managing a site according to claim 8, wherein states of the multiple nodes installed in the site are identified according to the security level, and the multiple nodes are controlled so that changes in the security level are made according to the matched preset conditions.
