IP Alarm Notification System with Video Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security systems using the Public Switched Telephone Network (PSTN) for alarm notifications can take over 30 seconds to establish a call, disrupt phone line availability, and lack remote video monitoring capabilities, leading to potential false alarms and inefficient emergency responses.
Innovation Solution
The system employs packet data communications over wireline and wireless networks to notify central monitoring stations, enabling multimedia voice and data sessions via 3GPP IP Multimedia Subsystem (IMS) for live and archived video/audio access to verify alarm legitimacy, allowing simultaneous emergency service coordination without seizing traditional phone lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PSTN is used for alarm notifications, then call reliability is ensured, but call establishment time exceeds 30 seconds and phone line availability is disrupted
Solution Approach 1:
The patent replaces the circuit-switched PSTN telephony system with packet-based IP communication protocols. The alarm notification system uses IP networks (such as 3GPP IMS) to transmit alarm data packets instead of establishing traditional voice calls, thereby eliminating call setup delays while maintaining communication reliability through packet routing and delivery mechanisms.
2Reliability
If PSTN phone line is seized for alarm call, then alarm notification is achieved, but customer cannot make or receive other calls including emergency services
Solution Approach 1:
The patent implements a multi-functional communication architecture where the alarm system uses IP-based communication that coexists with traditional PSTN services. The system can simultaneously handle alarm notifications via IP packets while leaving PSTN phone lines available for customer use, including emergency calls. The IP network provides an alternative communication path that does not interfere with traditional telephony services.
3Reliability
If conventional security systems are used, then alarm detection is achieved, but remote video monitoring capability is lacking
Solution Approach 1:
The patent combines alarm detection functionality with video monitoring capabilities into an integrated security system. The system merges sensor-based alarm detection with IP-networked video cameras and audio devices, allowing simultaneous detection of alarm conditions and retrieval of corresponding video/audio evidence. This integration enables agents to access live and archived video feeds through the same IP communication infrastructure used for alarm notifications.
Data Source
AI summary
Methods, systems, and products are disclosed for notification of alarms in security systems. An alarm is detected in a security system. An alarm code is associated to a camera, and video data is retrieved from the camera. An alarm notification address is retrieved and the video data is sent to the IP alarm notification address.
