The diagram illustrates a complete and efficient network infrastructure powered by the SDZ Link Easy Smart Managed Ethernet Switch. Internet connectivity from the ISP is delivered to the router, which functions as the DHCP server to automatically assign IP addresses across the network.

From the router, the connection is distributed to the SDZ Link managed switch, acting as the central network hub. The switch efficiently connects multiple devices including CCTV cameras, an NVR for video recording and monitoring, user devices such as laptops and PCs, a wireless access point for WiFi coverage, and a network printer.

This structured topology ensures stable communication, centralized management, and reliable performance for both surveillance and user network operations. With smart switching technology and seamless connectivity, SDZ Link provides a scalable and dependable solution for modern business and security environments.

Ensure maximum network stability and long-term equipment protection with our AI PoE Switch, engineered with built-in 4KV lightning and surge protection. Designed for demanding environments such as outdoor CCTV installations, industrial facilities, and commercial buildings, this switch delivers reliable power and high-speed data transmission while safeguarding connected devices from electrical surges and lightning strikes.

With intelligent PoE management and stable multi-port connectivity, it supports seamless integration for IP cameras, wireless access points, and other PoE-enabled devices. The robust metal housing enhances durability, while the advanced protection system minimizes downtime, reduces maintenance costs, and ensures uninterrupted network performance.

Ideal for surveillance systems, smart buildings, and enterprise networking solutions, our AI PoE Switch provides the reliability, protection, and performance your infrastructure demands.

AI Watchdog Protection is an intelligent monitoring feature designed to ensure continuous and stable network performance. It automatically monitors data transmission and PoE port activity in real time.

If the system detects abnormal behavior such as network freeze, data transmission failure, or device unresponsiveness (for example, an IP camera going offline), the AI Watchdog will automatically cut and restore power to the affected port. This auto-restart function helps recover connected devices without requiring manual intervention.

By reducing downtime and minimizing the need for on-site maintenance, AI Watchdog Protection enhances system reliability, improves operational efficiency, and ensures uninterrupted surveillance and network connectivity

Our PoE Switch is equipped with Ultra-Extended Mode, allowing greater flexibility in network installation.

In Normal Mode, the switch supports data transmission up to 100 meters at 100Mbps, which is the standard distance for most PoE applications.

By enabling Extended Mode, the transmission distance can reach up to 250 meters**, ideal for long-range CCTV installations and remote device deployment. This mode operates at 10Mbps, ensuring stable connectivity for surveillance systems and other essential network devices.

With a total power budget of 120W, the switch delivers reliable PoE performance while supporting extended coverage for larger areas.

Ultra-Extended Mode is perfect for warehouses, parking areas, industrial sites, and outdoor surveillance where devices are located far from the main network cabinet.
