Automated Device ID Assignment via DHCP for Surveillance Systems

Solution Overview

Problem

Manual configuration of device IDs for video surveillance front-end devices is labor-intensive and time-consuming, especially in large systems, increasing labor costs and prolonging the online setup process.

Innovation Solution

Front-end devices use their own identification information, such as MAC addresses, to register with a central management server, which assigns a unique device ID, allowing automatic configuration and online access without human intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual configuration of device IDs is used for each front-end device, then the device can be registered and connected to the video surveillance system, but the labor costs increase and the getting-online period is lengthened

Engineering Contradiction:

Improvedevice registrationVSAvoidgetting-online period

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The front-end device automatically obtains its device ID through DHCP protocol without requiring manual configuration. The device sends a DHCP request, receives the device ID automatically, and completes registration independently, eliminating the need for manual intervention and significantly reducing the getting-online period

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

A DHCP server is introduced as an intermediary between the front-end device and the video surveillance system. The DHCP server automatically assigns device IDs to front-end devices through standardized DHCP protocols, enabling automated registration and connection without manual configuration

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method for getting a device online, a method for sending addresses, a front-end device, a server and a surveillance system are provided, wherein the method for getting a device online includes: a front-end device carrying its own device identification to request a central management server for a registration; receiving a device address assigned by the central management server to the front-end device after the registration is successful; using the device address to request an online management server for getting online, receiving a request response fed back by the online management server. Through the above technical solution, the embodiment of the present invention solves the problem that the front-end devices need to be manually configured with device IDs one by one.
