IP Camera Repeater Function Wireless Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IP cameras are limited by the restricted coverage of wireless networks and interference from barriers, making it difficult to install and maintain network devices like bridges and repeaters, which are costly and complex to set up, and do not effectively expand network coverage to eliminate dead zones.
Innovation Solution
An IP camera with integrated repeater functions that can capture images, process signals, and forward packets between a root wireless access point and external devices, expanding network coverage by mediating communication signals and packets, even outside the initial wireless LAN coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If network devices such as bridges and repeaters are installed to expand wireless network coverage, then the transmission range and signal strength are improved, but the device complexity and installation cost increase
Solution Approach 1:
The patent combines the repeater function with the IP camera device, merging two separate functions (surveillance and network signal expansion) into a single integrated device. This eliminates the need for separate network devices and reduces overall system complexity while expanding wireless coverage.
Solution Approach 2:
The IP camera is designed to perform multiple functions: image capture, network communication, and wireless signal repetition. By making the device universal, it can expand network coverage without requiring dedicated repeater hardware, thereby reducing device complexity and installation costs.
2Reliability
If multiple network devices are installed to eliminate dead zones, then the wireless network coverage is improved, but the installation cost and complexity increase
Solution Approach 1:
The repeater functionality is merged into the IP camera module, allowing a single device to provide both surveillance and extended network coverage. This integration reduces the number of components needed, lowering installation costs and complexity while maintaining reliable wireless coverage extension.
Solution Approach 2:
The IP camera autonomously performs packet forwarding and signal repetition without requiring manual configuration of separate network devices. The device self-configures to extend the wireless network, eliminating the need for complex installation procedures and reducing overall system cost.
3Device complexity
If conventional IP cameras are used without repeater functions, then the device simplicity is maintained, but the network coverage is limited
Solution Approach 1:
The IP camera is enhanced with multi-functionality, incorporating repeater capabilities that allow it to not only capture images but also extend wireless network coverage. This adds network expansion capability without significantly increasing device complexity, as the repeater functions are integrated into the existing camera architecture.

AI summary
The present invention is to provide an IP camera having repeater functions, which includes an image-capturing module for capturing images, an image processor for processing the images, a central processor including a network communication module for activating the repeater functions and mediating communication between a root wireless access point (WAP) and an external device, and an antenna electrically connected to the network communication module in order for the IP camera to make wireless connection to the root WAP, upload the images to the Internet and serve as a repeater between the two WAPs, and a memory configured for storing operating software, a plurality of service set identifiers (IDs) and an authentication key. Due to the repeater functions of the IP camera, the external device can identify the IP camera by the IDs and then connect to the Internet, even if the external device is outside coverage of a wireless LAN.
