Product Description

The Dahua DH-PFS4226-24ET-240 is a professional Layer 2 managed PoE switch designed specifically for large-scale IP surveillance and enterprise network environments. It features 24 × 10/100 Mbps PoE ports, enabling reliable power and data delivery to IP cameras, access points, and other PoE-enabled devices.

For high-speed uplink connectivity, the switch provides:

• 2 × Gigabit RJ45 uplink ports
• 2 × Gigabit SFP ports (combo)

This ensures flexible backbone integration using both copper and fiber connections.

The switch supports IEEE 802.3af/at/bt and Hi-PoE standards, delivering:

• Up to 90 W on ports 1–2 (Hi-PoE for PTZ cameras)
• Up to 30 W on remaining ports
• Total PoE budget: 240 W

It includes advanced PoE management features, allowing real-time monitoring of power consumption and intelligent power allocation. Additionally, PoE Watchdog automatically detects and restarts unresponsive devices, ensuring continuous operation.

With long-distance PoE transmission up to 250 meters, VLAN support, QoS prioritization, and enterprise-grade security, this switch is ideal for large CCTV systems, campuses, and commercial networks.
