Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacation checks by law enforcement agencies are inefficient, requiring manual intervention and excessive battery consumption of body cameras, and lack effective video monitoring to ensure thorough dwelling inspections.
Innovation Solution
An on-demand security inspection system that coordinates police visits using predefined checklists, real-time communication, and video recording, leveraging vehicle and body-worn sensors to optimize battery usage and minimize human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If body camera records continuously throughout the entire shift, then all events are captured, but battery consumption becomes excessive and data files become very large
Solution Approach 1:
The body camera system transitions from continuous recording to periodic recording based on event detection. The system records continuously only when events of interest are detected (such as suspicious activities, alarms, or emergencies), and remains in a low-power state otherwise. This periodic action maintains reliable event capture while dramatically reducing battery consumption and data storage requirements.
Solution Approach 2:
The system uses feedback from sensors and detectors to trigger recording operations. When sensors detect potential events or anomalies, the system receives feedback and activates recording accordingly. This feedback mechanism ensures that recording occurs only when necessary, balancing complete event capture with energy conservation.
2Reliability
If body camera records continuously throughout the entire shift, then all events are captured, but data files become very large requiring extensive human review
Solution Approach 1:
By implementing periodic recording based on event detection rather than continuous recording, the system maintains complete capture of relevant events while significantly reducing the volume of data that requires human review. This directly reduces the time investment needed for data analysis and review.
Solution Approach 2:
The feedback mechanism triggers recording only when events of interest are detected, ensuring that the data reviewed by humans contains only relevant information. This eliminates the need to scan through large amounts of irrelevant footage, dramatically reducing review time while maintaining event capture completeness.
3Reliability
If officer manually checks each area and collects feedback, then thorough inspection is achieved, but time consumption increases
Solution Approach 1:
The inspection system incorporates automated sensors, detectors, and electronic devices that perform inspection tasks independently without requiring manual intervention for each measurement. The system self-monitors conditions such as intruder detection, environmental parameters, and security status, providing automated feedback that reduces the time officers spend manually checking each area while maintaining thorough inspection reliability.
Solution Approach 2:
The system replaces manual mechanical inspection processes with automated electronic sensing and detection systems. Sensors, cameras, and electronic detectors automatically monitor and report on inspection items, eliminating the need for officers to physically check each area and manually record findings, thereby reducing time consumption while maintaining inspection thoroughness.
4Use of energy by moving object
If body camera is turned on manually, then power consumption can be controlled, but operation becomes cumbersome requiring human intervention
Solution Approach 1:
The body camera system automatically activates and deactivates based on detected events and predefined conditions without requiring manual intervention. The system self-manages its operational state, turning on when events occur and turning off during normal periods, thereby maintaining power consumption control while eliminating the cumbersome manual operation requirement.
Solution Approach 2:
The system uses feedback from sensors and detectors to automatically control camera operation. When events are detected or conditions change, the system receives feedback and adjusts its operational state accordingly, eliminating the need for manual switching while maintaining control over power consumption.

AI summary
An on-demand security inspection system is provided for dispatching an investigator to a target dwelling. The investigator (e.g., a police officer) carries a video camera (e.g., a body cam). The inspection system comprises a service management server, a requestor interface, and an investigator interface. The requestor interface is configured to link a user to the service management server in order to specify a checklist. The investigator interface is configured to link a mobile unit (e.g., a vehicle control module or a handheld mobile unit) to the service management server in order to (1) communicate a plurality of checklist prompts to the mobile unit, and (2) return video data from the video camera captured according to the checklist prompts.
