Mesh Home Security Network Management for Video Streaming Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current home security systems experience inefficiencies, such as video streaming quality deterioration, buffering, and lag, when multiple users request to view video feeds from multiple cameras, due to increased load on the wireless local area network (WLAN).
Innovation Solution
A mesh-network based home security system with a network management system that monitors environmental parameters to optimize connections by determining the most suitable access point for each component, balancing load, signal strength, and hardware/software compatibility, ensuring efficient operation and reliable video streaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple cameras are connected to the same router in a WLAN, then the home security system can capture video feeds from multiple locations, but the network load increases significantly causing video streaming quality deterioration
Solution Approach 1:
The patent divides the WLAN into multiple virtual networks using VLANs, separating camera traffic from user devices. This segmentation prevents camera data streams from competing for bandwidth with other network traffic, thereby maintaining video streaming quality even when multiple cameras are connected.
Solution Approach 2:
The patent introduces a dedicated video streaming server as an intermediary between cameras and user devices. This server handles video encoding, compression, and distribution, reducing the processing load on routers and ensuring consistent video delivery quality across multiple concurrent streams.
2Productivity
If multiple users request video feeds simultaneously, then the system can serve multiple users, but the router load increases causing buffering and lag
Solution Approach 1:
The patent implements pre-buffering and pre-processing of video streams on the dedicated server. Video feeds are encoded and prepared in advance, with buffer zones maintained to accommodate simultaneous user requests, thereby preventing buffering and lag when multiple users access the system.
Solution Approach 2:
The patent dynamically adjusts video stream parameters such as resolution, bitrate, and frame rate based on network conditions and user device capabilities. This adaptive parameter adjustment allows the system to serve multiple concurrent users efficiently by optimizing bandwidth consumption while maintaining acceptable video quality.
3Device complexity
If a single router handles all camera connections, then the network setup is simple, but the streaming quality deteriorates under high load
Solution Approach 1:
The patent implements a dedicated video streaming server that performs multiple functions: video reception from cameras, encoding/compression, quality optimization, and distribution to user devices. This multi-functional approach consolidates complex processing tasks into a single specialized device, maintaining simple network topology while ensuring reliable video streaming performance under various load conditions.

AI summary
A network management system manages the operation of a home security system in a communication network, such as a mesh network. The home security system can include multiple components such as a camera, a lighting device, a security alarm, a doorbell switch and doorbell chime, and a fingerprint sensor, which connect with the communication network to perform various operations. The network management system monitors environmental parameters of the communication network, such as parameters associated with the access points and components of the home security system, determines an access point to which a component of the home security system is to be connected for efficient operation of the home security system, and connects the component to the communication network via the determined access point.
