Hi-PoE 16-port Full GigaPoE Switch

The ND-AHHSG1622V is a flagship 20-port All-Gigabit smart PoE++ hybrid switch (16 PoE + 2 Gigabit RJ45 + 2 Gigabit SFP) engineered for high-density surveillance and large-scale IoT networks. With a massive 300W power budget, quad 90W ports, and quadruple gigabit uplinks, it provides the ultimate high-bandwidth solution for modern IP infrastructures.

Core Features

• Quad 90W PoE++ (IEEE 802.3bt)Ports 1-4 deliver up to 90W each, allowing you to simultaneously power four heavy-duty PTZ cameras, high-performance wireless base stations, or digital signage terminals.
• Full Gigabit Architecture & Quad Uplink Equipped with 16*Gigabit PoE ports, 2*Gigabit RJ45 uplinks, and 2*Gigabit SFP slots. The 40Gbps switching capacity ensures smooth, non-blocking transmission for 16 channels of 4K HD video streams.
• AI Watchdog(Self-Healing System) Automatically monitors ports 1-16. If a connected device (like an IP camera) crashes or stops responding, the switch automatically reboots the specific port to restore connection without manual intervention.
• 250m Extend Mode One-key to extend transmission distance to 250 meters, breaking the 100m Ethernet limit. This simplifies cabling for large sites such as industrial parks, warehouses, and parking lots.
• One-Key VLAN Isolation Isolates PoE ports 1-16 to suppress broadcast storms and prevent IP conflicts. This layer of hardware security significantly enhances overall network stability and protects against unauthorized access.
• Power Priority Management Intelligently prioritizes power according to port numbers. When total consumption reaches the 300W limit, it ensures stable power to critical devices (Ports 1-4) by cutting power to lower-priority ports first.
• 4KV Industrial Surge Protection Equipped with professional 4KV protection for both ports and power supply to withstand lightning strikes and voltage surges in harsh outdoor or engineering environments.
• Rugged Design & Silent Operation Built with a galvanized steel shell for superior heat dissipation. The fanless design ensures zero-noise and 24/7 stable operation even in high-temperature environments (up to 55°C).
• Advanced Circuit Safety Built-in 300Winternal power supply featuring Over-Voltage Protection (OVP), short-circuit protection, and 8-core stable power delivery for maximum reliability.
