Audio Occupancy Simulation for Premises Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current premises security systems lack an effective method to deter intruders by simulating occupancy when the premises are unoccupied, as they rely solely on visual deterrents and do not utilize audio cues to create the illusion of presence.
Innovation Solution
A premises security system that uses audio/video devices to detect visitors and play back recorded ambient sounds to create the illusion of occupancy, adjusting sound levels and simulating movement through stereophonic techniques to deter unwanted visitors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio/video devices are used to detect visitors and provide visual deterrents, then security deterrence capability is improved, but the system lacks effectiveness when premises are unoccupied as no occupancy simulation is provided
Solution Approach 1:
The system performs preliminary action by recording ambient sounds during actual occupancy periods and storing them for later playback. This pre-captured audio data is then utilized during unoccupied periods to simulate presence, ensuring the security system remains effective regardless of actual occupancy status.
Solution Approach 2:
The system creates audio copies of the actual occupancy environment by recording and storing ambient sounds. These copied audio signatures are then played back during unoccupied periods to replicate the acoustic profile of an occupied premises, deceiving potential intruders into believing occupants are present.
2Device complexity
If only visual deterrents are used, then device complexity is reduced, but security effectiveness is insufficient as audio cues are not utilized
Solution Approach 1:
The system achieves multi-functionality by utilizing existing audio/video devices for multiple purposes: visitor detection, visual deterrence, audio recording during occupancy, and audio playback for occupancy simulation. This eliminates the need for separate dedicated components for each function, maintaining relative simplicity while significantly enhancing security effectiveness through multi-modal operation.
3Reliability
If audio content is played back to simulate occupancy, then occupancy illusion is created, but energy consumption increases due to continuous audio playback requirements
Solution Approach 1:
The system implements periodic action by playing back recorded audio content at intervals rather than continuously. Audio playback is triggered based on detected visitor presence or at scheduled intervals, allowing the system to maintain occupancy simulation effectiveness while consuming energy only when necessary, rather than operating continuously.

AI summary
A premises security system for providing audio simulating occupancy of a premises. The system includes a video doorbell having a presence sensor and a security hub component communicatively coupled with the video doorbell. The security hub component includes a microphone for capturing sound within the premises, at least one speaker positioned within the premises, an audio driver for driving the speaker, a storage device, and a processor coupled to the microphone, the storage device, and the audio driver. The processor executes machine-readable instructions that control the processor to: capture, using the microphone, audio content of sounds within the premises; store the audio content in the storage device; and control the audio driver to play the audio content through the speaker in response to receiving an indication of the presence of a visitor from the video doorbell.
