Mobile GPS Alarm Verification for False Alarm Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alarm systems require additional equipment installation, increasing costs and failing to effectively determine whether occupants are present in a monitored region, leading to false alarms.
Innovation Solution
Utilizing the GPS location of a mobile device to identify the presence of occupants and determine the likelihood of a real or false alarm by comparing the device's location with the monitored region, enabling central stations to make informed decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional equipment is installed in the monitored region for video or audio alarm verification, then the ability to determine occupant presence is improved, but the overall cost of the system increases
Solution Approach 1:
The patent uses the mobile device as an intermediary to provide location information about occupants. Instead of installing additional verification equipment, the system leverages the mobile device's GPS capabilities to determine whether occupants are present in the monitored region, thereby resolving the contradiction between accurate occupant detection and system cost.
2Reliability
If traditional alarm systems are used without GPS location data, then the system is simpler to implement, but false alarms cannot be effectively reduced
Solution Approach 1:
The system incorporates feedback by using mobile device location data to verify alarm conditions. When an alarm is triggered, the system checks the GPS location of mobile devices in the area to determine if occupants are actually present, providing feedback that helps distinguish true alarms from false alarms and improves overall system reliability.

AI summary
Systems and methods for reducing false alarms and providing a central station with information regarding occupants in a monitored region using the GPS location of a mobile device are provided. Some methods can include receiving a first signal indicative of a detected alarm condition in a monitored region, responsive to receiving the first signal, transmitting a second signal to a mobile device, receiving a third signal from a mobile device indicative of a location of the mobile device, and based on a location of the monitored region and the third signal indicative of the location of the mobile device, determining a likelihood of whether the detected alarm condition is real or false. Additionally or alternatively, some methods can include receiving a signal from a mobile device indicative of a location of the mobile device at predetermined periodic time intervals and irrespective of any detected alarm condition in the monitored region.
