Prediction Of False Alarms In Sensor-Based Security Systems
First Claim
1. A computer program product tangibly stored on a non-transitory computer readable hardware storage device, the computer program product for detecting changes in operational characteristics of a group of sensor devices deployed in a system, the computer program product comprising instructions to cause a processor to:
- collect sensor information from the group of sensor devices, with the collected sensor information including sensor operational data and sensor device metadata;
continually analyze the collected sensor information to detect changes in operational characteristics of a sensor device in the group of sensor devices, with the changes correlated to an imminent potential failure of the sensor device;
upon detection of a change in the operational characteristics of the sensor device that would indicate the potential failure,access a database that stores maintenance organization contact information;
generate based on the detected changes and the access to the database a request for maintenance on the sensor device; and
send the request to the maintenance organization contact.

Abstract
Techniques for detecting changes in operational characteristics of a group of sensor devices are described. The techniques collect sensor information from plural sensor devices deployed in a system, with the collected sensor information including sensor data and sensor device metadata. The techniques continually analyze the collected sensor information to detect changes in the operational characteristics of a sensor device in the group of sensor devices. Upon detection of changes in the operational characteristics of the sensor, a database that stores maintenance organization contact information is accessed and a request is generated for maintenance on the sensor device, which request is sent to the maintenance organization.

6. A system comprising:
-
a gateway to couple sensor information from plural sensor devices to a network; a server computer comprising processor and memory, the server computer coupled to the network; a storage device storing a computer program product for detecting conditions at a premises, the computer program product comprising instructions to cause the server to; collect the sensor information from the plural sensor devices, with the collected sensor information including sensor data and sensor device metadata; execute one or more unsupervised learning models to continually analyze the collected sensor information to produce operational states of sensor information; produce sequences of sensor state transitions; detect during the continual analysis of sensor data that one or more of the sequences of sensor state transitions corresponds to one of the sensor device being in a drift sequence, by correlating the determined drift state sequence to a stored determined condition to determine whether a potential false alarm could occur by the sensor device being in the drift sequence; access a database that stores maintenance organization contact information; and generate an alert based on the determined condition and the access to the database with the alert being a request for maintenance on the one of the sensor devices. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A computer implemented method comprises:
-
collecting sensor information from plural sensor devices deployed in a system, with the collected sensor information including sensor data and sensor device metadata; executing one or more unsupervised learning models to continually analyze the collected sensor information to produce operational states of sensor information; producing sequences of sensor state transitions; detecting during the continual analysis of sensor data that one or more of the sequences of sensor state transitions corresponds to one of the sensor device being in a drift sequence, by correlating the detected drift sequence to a stored determined drift sequence condition to determine whether a potential false alarm could occur by the sensor being in the detected drift sequence; determining from the sensor device metadata, age of the one sensor device in the detected drift condition; accessing a database by sensor device type to retrieve metadata on sensor devices of the type of the one sensor device in the detected drift condition, and having an age approximate to the determined age of the sensor device; accessing a database that stores maintenance organization contact information; and generating an alert based on the detected drift condition and the access to the database with the alert being a request for maintenance on the one sensor device.
