Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video security systems face challenges in managing and maintaining large networks of cameras, requiring substantial professional time for installation, configuration, and upgrades, with issues such as labor-intensive tasks, error-prone processes, and the need for proprietary drivers, leading to complex and time-consuming maintenance and upgrades.
Innovation Solution
A network video recording system that automatically powers, detects, configures, and records video cameras connected to a computer network, featuring a network video recorder with PoE capabilities and a client controller software for automated 'plug and play' functionality, eliminating the need for manual installation of software drivers or Ethernet switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual installation and configuration methods are used for video security systems, then system functionality is achieved, but installation and maintenance time becomes excessively long and labor-intensive
Solution Approach 1:
The system enables self-service through automatic camera detection, where the NVR automatically discovers cameras on the network, retrieves their information, and configures them without manual intervention. This eliminates the need for technicians to manually install drivers and configure each camera, dramatically reducing installation and maintenance time while allowing the system to service itself.
2Adaptability or versatility
If proprietary drivers are required for each IP security camera, then device compatibility is achieved, but system complexity and upgrade difficulty increase
Solution Approach 1:
The NVR is designed with universal compatibility to work with multiple camera types and protocols simultaneously. It supports both proprietary drivers for specific camera models and protocol-based communication (such as ONVIF) for standardized interfaces. This multi-functional approach allows the system to accommodate diverse camera devices without requiring separate management procedures for each type, simplifying upgrade and maintenance processes.
3Reliability
If large networks of cameras are deployed to meet security requirements, then security coverage is improved, but system manageability becomes overwhelming
Solution Approach 1:
The system implements feedback mechanisms where the NVR continuously monitors camera status, network conditions, and system performance. Automatic camera detection and provisioning provide real-time feedback about available devices, while the system tracks and manages camera locations and configurations. This feedback loop enables the system to automatically adapt to network changes and maintain manageability even as the number of cameras grows to cover extensive security requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system significantly reduces installation and maintenance time by automating camera detection and provisioning, allowing for efficient management of large networks with reduced manual intervention and improved scalability.
Implementation Method 1
The system responds to various network and camera conditions greatly reducing the amount of installation and maintenance time required to operate the system. Automated 'plug and play' feature automatically installs and provisions video cameras.
Data Source
AI summary
An apparatus and method is presented for network video management and recording of video signals and video analytics generated by a network of IP-enabled cameras. A set of IP cameras are connected in a LAN to a network video recorder further connected by LAN or WAN to a set of client stations. The client station operates a hybrid program including a web-browser and a native application operating on a computer. The network video recorder operates a media recorder to store video streams from the IP cameras into a media database and further operates a relational database for storing camera configuration data, device drivers, event information and alarms. The network video recorder includes a zero configuration networking discovery service for automatically detecting and downloading default configurations to the cameras. Client stations can stream video directly from IP cameras, receive recorded video streams and query the relational database for cameras and events.
