On October 28, 2025, the China International Social Public Safety Expo grandly opened at the Shenzhen Convention and Exhibition Center (Futian). This year's expo, with the theme "Digital Driven, Smart Innovation for the Future," focused on the application of cutting-edge technologies such as artificial intelligence, 5G, the Internet of Things, big data, machine vision, and low-altitude security. At the exhibition, we showcased two solutions: long-distance power supply to replace traditional transceivers, and CVR SD-WAN remote monitoring networking for security. Together, these solutions promote the evolution of security systems towards greater efficiency, reliability, and intelligence.

Optoelectronic Integration · Minimal Deployment
Long-distance power supply replaces traditional transceivers

At this year's Security Expo, we launched the targeted "Long-Distance Power Supply Replacing Traditional Transceivers" solution, effectively addressing core issues that traditional security networking has long faced, such as multiple fault points, difficult troubleshooting, complicated installation, messy cabling, and limited scalability. This provides enterprises, campuses, large warehouses, plazas, tunnels, and other scenarios with a simpler, more stable, and efficient deployment option.

The long-distance power supply solution that replaces traditional transceivers uses a fiber-optic composite cable as its core, enabling a single cable to transmit both video data and DC power simultaneously, without the need to lay separate power lines and fiber optics. This significantly simplifies the wiring structure and reduces labor and material costs. The solution breaks through the traditional 100-meter transmission limit, with a maximum coverage of up to 300 meters, perfectly meeting the requirements of longer-distance monitoring scenarios.

At the device level, we use a high-performance ZH-F1 single-port ONU, which is equipped with a PON port and a DC interface. It can access optical signals transmitted through a splitter, and its power output port supports up to 30W, fully meeting the power requirements of most surveillance cameras. A plug-and-play fiber server requires no debugging or configuration and can seamlessly connect to an NVR for video recording, enabling centralized storage and management of video data. Additionally, the solution supports full gigabit transmission, and the strong anti-interference characteristics of the composite optical-electrical cable effectively ensure image transmission quality when multiple cameras operate simultaneously. The video remains stable without flickering or interruption, providing a more stable and reliable long-distance power supply and data transmission solution for security surveillance systems.

In terms of system architecture, this solution achieves a fundamental optimization of the network structure. In traditional solutions, each monitoring point requires pairwise transceivers, whereas this solution uses an online ZH-F1 single-port ONU device for access, eliminating the need for paired configuration and directly reducing potential fault points by two-thirds. At the same time, the passive splitters deployed in the system do not require external power or regular maintenance, significantly reducing operational complexity while effectively saving energy costs. This innovative architecture thoroughly addresses the core pain points of traditional security networking schemes, such as excessive nodes, frequent faults, and complex maintenance, providing a more stable and reliable transmission guarantee for security systems.

After large-scale commercial verification by operator networks, this solution has demonstrated outstanding stability and reliability. The zero-threshold entry optical solution not only creates a clear competitive advantage over traditional solutions but also opens up an entirely new market track. It also brings considerable profit growth for enterprises, helping integrators and contractors overcome the challenges of homogeneous competition, effectively leaving behind industry stagnation, and achieving high-quality, sustainable development.

Integrated Cloud and Network · Full-Scale Connectivity
CVR SD-WAN Remote Monitoring Network

At this year's Security Expo, we launched our remote monitoring networked security solution, centered on the deep integration of the CVR video fusion cloud platform and SD-WAN technology. With an ultra-simple architecture, one-stop service, full optical connectivity, and exceptional compatibility, it provides an integrated cross-regional security management solution for enterprises, industrial parks, logistics warehouses, and chain supermarkets, among various other scenarios.

The Smart Guangxun CVR Video Fusion Cloud Platform is based on a cloud-edge-end integrated architecture and offers outstanding video access and processing capabilities. The platform fully supports mainstream protocols such as the national standard GB/T28181, GA/T1400, RTMP, and RTSP/ONVIF, allowing seamless connection with various cameras, NVRs, and smart gateway devices. Both new and existing equipment can be easily integrated for lightweight access to a massive number of resources. The platform supports multi-channel high-definition display from 720P up to 4K, provides 24/7 intelligent recording and accurate playback functions, and enables remote command and emergency response through PTZ control and two-way voice intercom, providing solid evidence for event tracing and accountability.

Additionally, the platform features an intelligent alarm hub that supports multi-channel real-time alerts, with critical alarms reaching relevant personnel within 5 seconds. Leveraging AI analysis capabilities, it can accurately identify over 100 risk scenarios and intelligently recognize people, vehicles, and objects in monitoring footage, providing intelligent support for a wide range of security applications.

CVR can also be deeply integrated with SD-WAN, creating a unique advantage for remote networking. The solution adopts an innovative 'headquarters central management' model, where headquarters monitoring staff only need to log into the CVR platform to directly view real-time footage and historical recordings from all branch cameras, without having to log into each branch's NVR or cameras individually. Moreover, both headquarters and branches do not need a fixed IP external network or public IP address to achieve secure networking, significantly reducing network deployment costs. In terms of deployment architecture, CVR functionality only needs to be enabled on the headquarters' integrated router, without enabling it at the branches, and the headquarters' integrated router does not require additional storage device configuration, greatly simplifying system complexity. The unique three-layer networking technology effectively solves the problem of branches being unable to access dedicated lines, while perfectly meeting headquarters' management requirements for unified data distribution and auditing.

CVR SD-WAN remote monitoring networking, with its advantages of flexible deployment, centralized management, low cost, and easy maintenance, is bringing a new digital transformation experience to the security industry, helping enterprises build a smarter, more efficient, and more economical cross-regional security management system.

Global Attention
Smart Light Speed Leads a New Era in Security

During this year's Security Expo, the Zhihui Guangxun booth attracted professional clients from Europe, Southeast Asia, the Middle East, and other regions around the world, thanks to its innovative technical solutions and mature practical applications. Overseas customers highly praised the cost-effectiveness of the long-distance power supply solutions and the centralized management features of CVR SD-WAN, particularly appreciating the stability and ease of deployment demonstrated in real-world scenarios.
