Alarm Signal Delay Mechanism for False Alarm Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems often transmit false alarms to central monitoring stations, leading to inefficient use of time and manpower for verification, as they lack effective methods to confirm or deny alarm signals before notification.
Innovation Solution
Implementing an alarm processing device that detects user interactions with a security system, such as enrollment in an alarm notification service and user device actions, to delay the transmission of alarm signals until user confirmation or denial is likely, thereby reducing false alarms and minimizing user response at the central monitoring station.

Engineering Contradiction Analysis
1Speed
If the alarm signal is transmitted immediately to the central monitoring station, then early notification of alarm conditions is achieved, but false alarms are transmitted leading to inefficient use of time and manpower
Solution Approach 1:
The system performs preliminary verification actions before transmitting the alarm signal. When an alarm condition is detected, the system first checks whether delay actions are detected (such as user interactions or system conditions) before transmitting to the central monitoring station. This preliminary check prevents false alarms from being transmitted while still allowing legitimate alarms to be communicated promptly.
2Reliability
If the operator verifies the alarm signal by contacting the user before transmission, then false alarms are reduced, but time and manpower are substantially consumed
Solution Approach 1:
The system performs self-verification by automatically detecting delay actions that indicate the alarm signal should be transmitted. Instead of requiring operator intervention to contact the user for verification, the system monitors for specific conditions (such as user device interactions or system states) that automatically confirm the legitimacy of the alarm, thereby eliminating manual verification time while maintaining accuracy.
3Reliability
If the user is required to confirm the alarm signal via mobile application before transmission, then false alarms are reduced, but the transmission is substantially delayed
Solution Approach 1:
The system dynamically adjusts the transmission timing based on detected conditions. Rather than requiring user confirmation in all cases, the system monitors for delay actions and only delays transmission when such actions are detected. If no delay actions are detected within a predetermined time period, the system transmits the alarm signal immediately, thus maintaining speed while still reducing false alarms through conditional delay.

AI summary
Systems and methods for delaying transmission of an alarm signal responsive to detecting delay actions indicative of progress towards confirming or denying the alarm signal are provided and can include an alarm processing device receiving the alarm signal and determining whether a user device is enrolled in an alarm notification service. When the user device is enrolled in the alarm notification service, the alarm processing device can transmit a notification to the user device, start a delay timer, and determine whether a first delay action associated with the user device is detected prior to expiration of the delay timer. When the first delay action is detected prior to the expiration of the delay timer, the alarm processing device can alter the delay timer consistent with a next delay action associated with the user device and, when the delay timer expires, transmit the alarm signal to the central monitoring station.
