Bridge Device Integrating Alarm Panel and Camera for False Alarm Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems face high false alarm frequencies due to sensors detecting objects other than the monitoring target, leading to difficulties in matching alarm information with camera images, increased costs, and challenges in providing evidential data for legal disputes.
Innovation Solution
A bridge device that registers zone numbers for cameras, analyzes images to sense motion, generates event information in the same format as alarm information, and transmits this information to a monitoring server, allowing for integration with alarm panel data and storage of temporary images in a cloud server for easy verification and logging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are used to detect alarm conditions in monitoring areas, then alarm detection capability is improved, but false alarm frequency increases due to detecting objects other than monitoring targets
Solution Approach 1:
The patent introduces a bridge device as an intermediary component between the alarm panel and camera. This bridge device receives alarm information from the alarm panel, retrieves corresponding image data from the camera through its image storage unit, and transmits both to the monitoring center. This intermediary structure enables the integration of visual evidence with alarm data, allowing operators to distinguish between genuine threats and false alarms caused by non-target objects.
2Measurement precision
If cameras are connected to separate systems from alarm panels, then image monitoring capability is improved, but system complexity increases and matching between alarm and image becomes difficult
Solution Approach 1:
The patent merges the alarm panel system and camera system through a bridge device that acts as a unified interface. The bridge device connects to both the alarm panel (receiving alarm information) and the camera (accessing image data), combining previously separate systems into an integrated architecture. This merging eliminates the need for separate education programs and simplifies operator workflows while maintaining the independent functionality of each component.
Solution Approach 2:
The bridge device serves as an intermediary that reconciles the previously separate alarm panel and camera systems. It manages the connection between these systems, handling alarm information retrieval and image data acquisition without requiring complex direct integration between the alarm panel and camera, thus reducing system complexity.
3Productivity
If alarm information is transmitted as digital signals only, then transmission efficiency is improved, but evidential data capability is reduced for legal disputes
Solution Approach 1:
The patent combines digital alarm signals with visual image data into a unified transmission package. The bridge device retrieves image data from the camera's image storage unit and transmits it alongside alarm information to the monitoring center. This combination maintains the efficiency of digital signal transmission while enriching the data with visual evidence, providing comprehensive evidential capability for legal disputes without sacrificing transmission speed.

AI summary
Disclosed is a bridge device supporting an alarm format, which transmits an event which occurs based on an image of a camera that photographs a monitoring area of an alarm panel in an alarm format according to an alarm format of an alarm panel transmitting alarm information in a predetermined alarm format when sensing by a sensor in the monitoring area in the alarm format and supports to interlock with the alarm panel while providing an image of the monitoring area where an event corresponding to the alarm information of the alarm panel.
