Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveillance camera systems lack the ability to easily set and register multiple communication methods with different bandwidths, limiting their flexibility and efficiency in wireless communication between cameras and controllers.
Innovation Solution
A surveillance camera system that allows wireless communication between cameras and controllers using various methods (5 GHz wireless LAN, 2.4 GHz wireless LAN, and DECT) by performing registration processing and selecting the optimal communication method based on environmental values such as packet error rate and signal strength, enabling seamless data transmission and control operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication methods with different bandwidths are supported, then communication flexibility and adaptability are improved, but device complexity and difficulty of registration increase
Solution Approach 1:
The controller performs registration processing for all communication methods in advance. During registration, the controller stores connection information for multiple communication methods (first communication method and second communication method) in association with each surveillance camera. This preliminary setup eliminates the need for complex real-time selection and registration operations during actual use.
Solution Approach 2:
The controller acts as an intermediary that manages multiple communication methods. It stores and manages connection information for different communication methods, and automatically selects appropriate methods based on environmental conditions. This intermediary role simplifies the system architecture by centralizing the complexity in the controller rather than requiring complex logic in each camera device.
2Reliability
If communication method selection is based on environmental values, then communication reliability is improved, but measurement and decision complexity increase
Solution Approach 1:
The surveillance camera measures environmental values (such as bandwidth conditions) and feeds back this information to the controller. The controller uses this feedback to automatically select the most appropriate communication method from the registered options. This feedback mechanism ensures reliable communication by continuously adapting to environmental conditions without requiring complex manual intervention.
Solution Approach 2:
The surveillance camera autonomously measures environmental values and determines which communication method to use based on these measurements. This self-service capability eliminates the need for external intervention in communication method selection, reducing operational complexity while maintaining high reliability through environment-aware automatic selection.
