Surveillance-Assisted Patrol System for Detecting Concealed Suspects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Law enforcement patrols are ineffective in detecting concealed suspects, as criminals often hide when patrols approach, leading to undetected criminal activity after the patrol has left the area.
Innovation Solution
A surveillance-assisted patrol system that uses stationary cameras to capture reference images of a location when a patrol is present and compares them with images taken at different times to detect concealed suspects, transmitting alerts when differences are found, indicating the presence of hidden individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If patrols rely solely on direct observation, then personnel safety and resource efficiency are maintained, but concealed suspects cannot be detected
Solution Approach 1:
The patent introduces surveillance cameras as an intermediary device between patrols and concealed suspects. The cameras capture images that are then analyzed to detect suspects hiding from patrols, allowing indirect detection without requiring suspects to be directly visible to patrol personnel.
Solution Approach 2:
The patent replaces the mechanical system of direct human observation with an automated image capture and analysis system. Electronic processors analyze captured images to detect concealed suspects, substituting human visual inspection with automated computational analysis.
2Reliability
If patrols increase presence in an area, then crime deterrence improves, but criminal activity may shift to periods after patrol departure
Solution Approach 1:
The patent captures reference images during patrol presence as a preliminary action. These images serve as a baseline to compare against future images, enabling detection of suspects who emerge after patrols leave, thus extending the protective effect beyond the actual patrol duration.
Solution Approach 2:
The system establishes feedback by comparing images taken during patrol presence with images taken afterward. When differences indicating concealed suspects are detected, alerts are generated, creating a feedback loop that extends surveillance effectiveness beyond the patrol's physical presence.
3Reliability
If patrols continuously monitor all areas, then crime detection improves, but resource consumption and operational costs increase
Solution Approach 1:
The patent applies partial action by using surveillance cameras selectively at locations where patrols are present or have recently been, rather than continuously monitoring all areas. This provides sufficient surveillance coverage where needed while reducing overall resource consumption.

AI summary
Systems and methods for surveillance-assisted patrol. One system includes an image capture device associated with a location, a patrol object, and a server communicatively coupled to the image capture device and the patrol object. The server includes an electronic processor configured to receive geolocation data for the patrol object. The electronic processor determines, based on the data, whether the patrol object is within a predetermined distance from the location, and, in response to determining that the patrol object is within the predetermined distance, captures a reference image of the location via the image capture device. The electronic processor accesses a second image corresponding to the location, captured at a different time than the reference image. The electronic processor compares the reference image to the second image to determine a difference. The electronic processor, in response to determining the difference, transmits, via the transceiver, a patrol alert to an electronic device.
