Security Marking System with Sensor-Triggered Marker Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security systems face challenges in identifying intruders and tracing stolen property due to delays in police response and the difficulty in establishing intruder identity, especially when burglars conceal their features, and the quick disposal of stolen goods makes recovery difficult.
Innovation Solution
A security marking system that includes marker deployment devices and sensors, where sensors detect activity and trigger the deployment of a unique marker liquid that can be applied to intruders or valuables, allowing remote activation and identification, even when communication with a remote device is limited, ensuring the marker can be traced back to the location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alarm systems are used to detect intruders, then intruder detection capability is improved, but response time is insufficient due to delay in police arrival
Solution Approach 1:
The system applies marker liquid to intruders as a preliminary action during the intrusion itself, rather than attempting to identify them after the fact. This immediate marking occurs while the intruder is still present, eliminating the time loss associated with delayed police response and identification procedures.
Solution Approach 2:
The system replaces the mechanical/police response system with an automated chemical marking system. Instead of relying on police arrival and manual identification, the system automatically detects intruders via sensors and applies marker liquid, substituting the slow mechanical response with an immediate automated chemical process.
2Ease of operation
If cameras are used to remotely view intruders, then remote monitoring capability is improved, but intruder identification is difficult when features are concealed
Solution Approach 1:
The marker liquid contains fluorescent or phosphorescent materials that cause visible color changes or glow under specific lighting conditions. This allows clear visual identification and differentiation of marked intruders, overcoming the limitation of concealed features by providing distinctive visual markers that cannot be hidden.
Solution Approach 2:
The marker liquid acts as an intermediary substance that bridges the gap between intruder detection and identification. Rather than relying directly on visual observation of concealed features, the system uses the marker liquid as a mediating element that provides clear, visible identification marks on the intruder's clothing or belongings.
3Productivity
If property is stolen and quickly disposed of, then offender profit is improved, but property recovery becomes difficult
Solution Approach 1:
The marker liquid is applied to property as a preliminary action during the theft itself. This immediate marking ensures that even if property is quickly disposed of or mixed with other goods, the unique marker remains on the stolen items, enabling reliable identification and recovery regardless of how rapidly the offender attempts to dispose of the property.

AI summary
A method of security marking, in a system which includes one or more marker deployment devices, each marker deployment device for deploying a marker liquid in a corresponding deployment region, and one or more sensors, each sensor for detecting activity within a corresponding sensor detection region, wherein each marker deployment region overlaps one or more sensor detection regions at least partially and wherein for each marker deployment region the overlapping one or more sensor detection regions include at least one sensor detection region corresponding to a sensor capable of recording video.
