Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video security systems face challenges in managing and recording data from remote security devices over IP networks, requiring extensive manual configuration and maintenance, with complexities increasing as network size grows, and lacking a standardized 'plug and play' solution for IP security devices.
Innovation Solution
A network video recording system that automatically powers, detects, configures, and records video cameras connected to a computer network, using a network video recorder with PoE capabilities and control software for automated 'plug and play' functionality, eliminating the need for manual software installation and external Ethernet switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual configuration and installation of proprietary drivers is used for each IP security device, then device compatibility and control are achieved, but installation and maintenance time increases substantially
Solution Approach 1:
The system enables automatic detection and configuration of IP security devices. When a camera is connected to the network, the NVR automatically detects it, assigns an IP address, and configures recording parameters without requiring manual driver installation or configuration by technicians.
Solution Approach 2:
The NVR is designed to work with multiple types of IP security devices from different manufacturers through a universal interface. The system provides a standardized method for detecting and configuring various camera types, eliminating the need for proprietary drivers for each device type.
2Adaptability or versatility
If Ethernet networks and IP routing are used to expand security network coverage, then network reachability and scalability are improved, but system management complexity increases
Solution Approach 1:
The NVR acts as an intermediary device that simplifies network management. It handles IP address assignment, device detection, and configuration automatically, shielding users from the complexity of Ethernet networking, IP routing tables, and DHCP configurations while enabling network expansion.
3Area of stationary object
If multiple campuses are monitored at a single security site using Internet connectivity, then monitoring coverage area is expanded, but firewall management and security configuration complexity increases
Solution Approach 1:
The NVR serves as a centralized intermediary that manages remote camera connections. It handles the complexity of firewall configurations and Internet connectivity for multiple campuses, providing a unified interface for monitoring while isolating users from network security configuration complexities.
4Reliability
If proprietary drivers are used for each IP security camera, then device-specific functionality is controlled, but upgrade and maintenance processes become time-consuming
Solution Approach 1:
The NVR implements a universal communication protocol that works with multiple camera types and manufacturers. This eliminates the need for proprietary drivers while maintaining reliable device control through standardized commands for recording, playback, and camera configuration.
Solution Approach 2:
The system automatically detects camera types and configures appropriate settings without requiring manual driver installation or updates. The NVR maintains a library of supported camera types and automatically selects the appropriate configuration profile when a camera is detected.
5Volume of stationary object
If digital video recorders store video data in large databases, then video storage capacity is increased, but database maintenance and data management complexity increases
Solution Approach 1:
The NVR automatically manages video database maintenance tasks including data retention policies, old data archiving, and storage optimization. The system self-adjusts recording parameters based on available storage space and automatically purges or archives data according to configured retention periods without user intervention.
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.
