Security Camera Cable Assembly with Integrated Processing Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security cameras with distinct processing modules are too large and heavy to be installed by dangling them from the camera head, requiring separate mounting and making it difficult to fit through apertures that can be covered by the camera head, complicating installation and increasing the camera's visibility.
Innovation Solution
A miniaturized security camera design with a cable assembly and integrated processing module that is lightweight enough to be supported by the camera head, featuring separate image processing and power PCBs housed within a compact module, and a micro-coaxial cable for efficient signal transfer, along with a heat spreader for thermal management, allowing the processing module to be transparent during installation and easily concealed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the processing module is separated from the camera head, then the camera head can be miniaturized for surreptitious surveillance, but the processing module becomes too large and heavy to be supported by the camera head
Solution Approach 1:
The camera system is divided into two separate components: a miniaturized camera head containing only the lens and image sensor, and a separate processing module containing the image processing circuitry and power supply. This segmentation allows the camera head to be sufficiently small for surreptitious surveillance while the processing module handles the bulkier components.
Solution Approach 2:
The processing module is designed to be insertable through an aperture in the mounting surface and hang behind the camera head, with the cable extending through the aperture. The processing module essentially nests within the space behind the mounting surface, allowing the camera head to remain small and mounted on the surface while the processing module occupies the space behind it.
2Ease of operation
If the processing module is miniaturized to fit through the aperture, then installation becomes easier and concealment is improved, but heat dissipation becomes more difficult
Solution Approach 1:
The processing module is designed with a compact form factor that fits through a small aperture in the mounting surface. By utilizing the three-dimensional space behind the mounting surface, the module achieves a compact size that facilitates easy installation through the aperture while still accommodating the necessary heat dissipation features.
3Weight of moving object
If the cable assembly is made lightweight for support by the camera head, then installation simplicity is improved, but the cable and connection strength may be compromised
Solution Approach 1:
The cable assembly uses a micro-coaxial cable design that optimizes the balance between weight and strength. The cable incorporates multiple conductors with appropriate gauges to provide sufficient electrical connection strength while keeping the overall cable assembly lightweight enough to be supported by the camera head.

Function Achieved in This Case
Enables easy installation and concealment of the processing module by allowing it to dangle from the camera head, maintaining a compact camera head size while ensuring efficient heat dissipation and reliable operation, similar to integrated cameras, without the need for separate mounting of the processing module.

AI summary
A security camera includes a camera head and a cable assembly with an integrated processing module. The camera head contains a lens and an image sensor, while the processing module contains image processing circuitry for processing images obtained using the image sensor and power circuitry used to power the image processing circuitry and the camera head. A cable connects the camera head and the processing module. The processing module is sized to fit through an aperture in a mounting surface that can be covered by the camera head when the camera head is mounted to the mounting surface, which facilitates ease of installation.
