Security System Alarm Verification via VoIP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security systems often trigger false alarms, leading to unnecessary emergency services dispatches and associated costs, as they lack efficient verification mechanisms before alerting authorities.
Innovation Solution
A security system with a central monitoring station that uses wireless communication and two-way interactive voice capabilities to verify alarm conditions through Voice-over Internet Protocol calls, allowing agents to confirm the validity of alarms before summoning emergency services, and incorporating a takeover module for retrofitting existing systems and utilizing powerline-to-Ethernet adapters for sensor connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional security systems trigger alarms immediately upon detection, then alarm response time is improved, but false alarm rate increases
Solution Approach 1:
The system performs preliminary verification actions before triggering the alarm. When a sensor detects a potential alarm condition, the system first attempts to contact the premises through voice communication to verify the condition before activating the alarm signal to emergency services, thereby reducing false alarms while maintaining rapid response capability
Solution Approach 2:
The system introduces an intermediary verification step between detection and alarm activation. A voice communication intermediary is used to confirm alarm conditions with occupants before triggering the alarm, serving as a mediator that filters out false alarms while allowing genuine threats to proceed to emergency notification
2Reliability
If verification mechanisms are added before alarm dispatch, then false alarm rate decreases, but system complexity increases
Solution Approach 1:
The system uses self-service verification by automatically attempting voice communication with occupants to confirm alarm conditions without requiring manual intervention from monitoring personnel. The system serves itself by autonomously verifying conditions through pre-programmed communication protocols, reducing operational complexity while maintaining high reliability
Solution Approach 2:
The system replaces manual verification mechanisms with automated electronic communication systems. Instead of requiring operators to physically verify alarms, the system uses voice over IP and automated calling systems to confirm conditions electronically, substituting mechanical/manual processes with automated electronic verification that reduces overall system complexity
3Loss of energy
If Voice-over Internet Protocol calls are used for verification, then communication cost decreases, but call reliability may worsen
Solution Approach 1:
The system dynamically adapts communication methods based on connection success. If VoIP calls fail to connect or verify conditions, the system automatically switches to alternative communication channels such as traditional telephony or direct alarm activation, providing dynamic communication routing that maintains reliability while optimizing cost through preferred VoIP usage when available
Solution Approach 2:
The system prepares backup communication pathways in advance to cushion against VoIP connection failures. Multiple communication channels are pre-configured so that if the primary VoIP path fails, alternative paths are already available to ensure verification can complete, providing beforehand cushioning against network unreliability

AI summary
A sensor associated with a security system determines an electrically open circuit. An identifier identifies the open circuit, which may then be used to retrieve video data trained to a surveillance area associated with the sensor.
