Building Monitoring Device Acoustic Operator Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building monitoring devices lack clear and reliable methods to inform individuals within the monitored area about the activation status and the identity of the operator initiating surveillance, potentially leading to unauthorized access or lack of consent.
Innovation Solution
Integration of an electronic output unit, such as a loudspeaker, within the monitoring device to emit unique acoustic signals when activated by a remote control device, along with encryption and signature transmission via a software certificate, ensuring secure and identifiable communication between the monitoring device and remote control device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no output unit is integrated into the monitoring device, then the device complexity is reduced, but the reliability of informing individuals about activation status and operator identity deteriorates
Solution Approach 1:
The output unit is integrated directly into the monitoring device, combining the notification function with the monitoring device itself. This eliminates the need for separate notification devices and ensures that activation status and operator identity information is reliably communicated to individuals in the monitored area.
2Reliability
If unique signals are not assigned to remote control devices, then the device complexity is reduced, but the ability to identify operator identity deteriorates
Solution Approach 1:
Each remote control device is assigned a unique signal or identifier, segmenting the control authority among different operators. This allows the system to distinguish between different operators and reliably identify who initiated the monitoring activation.
3Reliability
If encryption and signature transmission are not implemented, then the device complexity is reduced, but the security against unauthorized access deteriorates
Solution Approach 1:
Encryption and signature transmission are implemented in advance to establish secure communication channels before monitoring activation. The remote control device and monitoring device exchange cryptographic credentials beforehand, ensuring that only authorized operators can activate monitoring and that the activation signals cannot be spoofed or intercepted.

AI summary
The invention relates to a building monitoring device comprising at least one monitoring device (12), in particular an indoor camera, and at least one remote control device (14) located away from the monitoring device (12), which is provided for activating the at least one monitoring device (12) by at least one operator (18). It is proposed that the monitoring device (12) has at least one output unit (16) which is provided for outputting a signal (20) uniquely assigned to the remote control device (14) and/or an operator (18) of the remote control device (14) when the monitoring device (12) is activated by means of the remote control device (14).
