Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
CCTV installations face challenges in accurately adjusting the field of view due to distance from the monitoring location, leading to inefficiencies and difficulties in correcting shifts caused by external factors, resulting in suboptimal installation and increased operational costs.
Innovation Solution
A device comprising a first laser generation module, an optical module, a driving module, and a control module that generates a projection image of the field of view, allowing on-site adjustment of the surveillance camera without relying on monitor images, and includes additional features for image analysis and facility monitoring to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the camera and monitor are installed at relatively far apart locations for security coverage, then the surveillance coverage area is improved, but the operator cannot check the exact field of view during installation and adjustment
Solution Approach 1:
A projection device is introduced as an intermediary tool between the camera and the operator. The projection device projects the camera's field of view onto the monitored area, allowing the operator to see the exact coverage area directly at the installation location without needing to be at the remote monitor location.
Solution Approach 2:
The field of view is copied and projected onto the monitored area using a projection device. This creates a visual replica of the camera's coverage area that can be directly observed at the installation location, enabling accurate field of view checking without requiring the operator to be at the remote monitor.
2Adaptability or versatility
If the camera direction is adjusted through remote communication while installing, then the installation distance flexibility is improved, but the installation time and communication requirements increase
Solution Approach 1:
The projection device enables the operator to independently adjust and verify the camera direction without requiring continuous communication with a remote operator. The operator can directly observe the projected field of view and make adjustments based on visual feedback, making the installation process self-sufficient and faster.
3Productivity
If the filming direction is fixed for operational efficiency, then the operational cost is reduced, but the ability to correct field of view shifts after installation difficulties increases
Solution Approach 1:
The projection device provides a dynamic solution that works with fixed camera installations. When field of view shifts occur, the projection device can be used to quickly identify the new coverage area and determine the necessary adjustments, enabling efficient correction while maintaining the overall fixed-operation philosophy.
