The DH-PFS4226-24ET-240-V3 is a Layer 2 managed PoE switch designed for medium to large-scale surveillance and networking applications. It provides 24 × 100 Mbps PoE ports and 2 × Gigabit uplink ports (RJ45/SFP combo), ensuring reliable connectivity and long-distance transmission.
With Intelligent PoE management, including power consumption control, overload protection, Green PoE, and legacy support, it ensures efficient and safe power distribution. The red port supports 90W IEEE802.3bt Hi-PoE, making it suitable for high-power devices.
Additional features include web-based management with a user-friendly interface, VLAN support, QoS prioritization, link aggregation, port mirroring, and security functions such as IP/MAC binding and IEEE802.1x authentication. Its robust design supports 250 m long-distance PoE transmission, making it ideal for surveillance deployments in offices, schools, hotels, and enterprises.
