Mobile Security Device for Guard Patrol Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile security guards often lack awareness of visually and audibly blocked surroundings during patrols and face challenges in verifying the completion of designated rounds, as they are away from central security consoles with displays and sensor presentations.
Innovation Solution
A Mobile Security Device (MSD) that provides real-time sensor data and orientation information, allowing guards to be aware of their surroundings and certifies the visitation of checkpoints through a system of sensors and communication channels with a central security station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a mobile guard patrols alone without central console equipment, then mobility and response time are improved, but awareness of blocked surroundings and verification of checkpoint visits deteriorate
Solution Approach 1:
A portable sensor unit is introduced as an intermediary device that the guard carries during patrols. This unit contains sensors (audio, visual, environmental) that detect surroundings and transmit data wirelessly to both the central console and the guard's handheld device, enabling awareness of blocked areas without requiring the guard to return to the central console
Solution Approach 2:
The system implements real-time feedback by continuously transmitting sensor data from the portable unit to the guard's handheld device and to the central console. This allows the guard to immediately see audio/video feeds from concealed locations and receive alerts about detected events, creating a closed-loop information system that maintains situational awareness during mobile patrols
2Ease of operation
If a mobile guard patrols alone without central console equipment, then mobility is improved, but verification of checkpoint visits deteriorates
Solution Approach 1:
The portable sensor unit and handheld device enable the guard to independently verify and document checkpoint visits without requiring central console equipment. The system automatically records the guard's location via GPS, timestamps checkpoint arrivals, and allows the guard to upload verification data (photos, notes) directly from the field, with all information automatically transmitted to the central console for verification
Solution Approach 2:
The system replaces the mechanical requirement of returning to the central console for verification with an automated electronic system. GPS tracking, wireless communication, and automatic timestamping substitute for manual reporting procedures, providing reliable verification of checkpoint visits while maintaining guard mobility
3Loss of information
If sensor data is transmitted in real-time to mobile device, then awareness of surroundings is improved, but energy consumption increases
Solution Approach 1:
The system uses periodic transmission of sensor data instead of continuous streaming. The portable sensor unit captures audio and video feeds periodically or triggers transmission only when events are detected (motion, sound thresholds), reducing constant data transmission while maintaining awareness of significant occurrences during patrols
Solution Approach 2:
The system transmits partial data sets based on priority and event significance. Routine environmental readings are transmitted less frequently, while high-priority events (detected intruders, alarms, unusual activity) trigger immediate full data transmission, providing necessary information while minimizing overall energy consumption

System, device and methods that provide proximate environmental and security intelligence to a guard making a security tour or round in an installation, as well as that provide for certifying that the guard has visited designated and known checkpoints on or about the times at which the guard is expected at those checkpoints.
