Industrial Applications

1. SME IP Surveillance & Security Deployment

The 16 PoE+ ports with a 225W power budget provide stable power for high-definition IP cameras, and SFP uplink slots allow long-distance transmission to a central NVR. Layer 3 routing facilitates separate subnets for security cameras and corporate traffic to ensure smooth operations.

Problem Solved

Reduces cabling costs while ensuring high-bandwidth, isolated video streams without burdening the core router for local VLAN routing.

2. Multi-Storey Smart Hotel Network Architecture

Powering multiple ceiling-mounted Wireless APs and VoIP phones on different floors. RIP dynamic routing and VLAN configurations allow seamless guest and staff network separation.

Problem Solved

Resolves the complexity of managing IP addresses across different floors using its on-board DHCP Server and DHCP Relay, minimizing inter-VLAN routing latency.

3. Automated Warehouse IoT Connectivity

Managed switch properties with robust QoS ensure real-time, latency-sensitive barcode scanners and AGVs communicate instantly. PoE+ enables powering of industrial wireless access points without separate power drops.

Problem Solved

Eliminates communication jitter and dropped connections by using 802.1p priority queues and loopback protection in challenging warehouse environments.
