Bluetooth Camera Bilateral Control via Notification Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera control technologies using Bluetooth communication are unilateral, allowing only remote devices to control cameras without the ability for cameras to send information back, limiting their functionality and intelligence.
Innovation Solution
Implementing a method for bilateral control in Bluetooth communication systems that enables cameras to transmit notification messages, such as memory full alerts or security alerts, to remote devices, allowing for intelligent camera operations and IoT integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If unilateral camera control is implemented, then the control function is simple to implement, but the camera cannot send information back to the remote device
Solution Approach 1:
The patent implements a feedback mechanism by enabling the camera to send notification messages back to the remote device through Bluetooth communication. The camera can now transmit information such as memory status, battery level, and surveillance alerts to the remote device, creating a bidirectional communication channel that was previously unavailable in unilateral control systems.
2Adaptability or versatility
If bilateral control is added to enable camera to send information, then the intelligence function is improved, but the communication protocol becomes more complex
Solution Approach 1:
The patent applies multi-functionality by enabling the Bluetooth communication interface to handle both control commands from the remote device and notification messages from the camera. The same communication channel is used for bidirectional data exchange, allowing the system to perform multiple functions (control and feedback) without adding separate dedicated channels or interfaces.
Solution Approach 2:
The patent inverts the traditional unilateral control model by enabling the camera (previously a passive device) to become an active information source. Instead of only the remote device initiating communication, the camera can now independently initiate notification messages to inform the remote device of important events or status changes.
3Adaptability or versatility
If notification service is implemented, then the IoT intelligence function is enhanced, but the power consumption increases
Solution Approach 1:
The patent implements periodic action by using Bluetooth Low Energy (BLE) technology that operates in periodic transmission modes. The camera can enter low-power sleep states between transmission events and only activate Bluetooth communication when specific trigger events occur (such as memory full, battery low, or security alerts), rather than maintaining continuous communication.

AI summary
In a method for controlling a camera by using Bluetooth communication in a wireless communication system, a method performed by a first device comprises transmitting to the camera a command message including camera control information for controlling a specific function of the camera; transmitting to the camera a configuration message for setting a trigger point of the camera, where the trigger point is a condition by which specific information is received from the camera; and receiving a notification message including the specific information from the camera.
