Name: 16-Port PoE Switch
Brand: Dahua
SKU: PFS4218-16ET-240

Feeds a Fast Ethernet camera network and links it to the backbone over gigabit combo uplinks.

A Layer 2 managed switch with sixteen Fast Ethernet PoE ports and two gigabit combo uplinks. It feeds edge devices such as cameras and access points straight over the cable, and gathers VLAN, port mirroring and IGMP snooping settings in a browser interface.

Key features

Intelligent PoEFeeds IEEE802.3af, IEEE802.3at, Hi-PoE and IEEE802.3bt devices; port 1 and port 2 reach 90 W.

Long distance transmissionCarries PoE power up to 250 m, so remote camera points need no extra power box.

PoE watchdogShuts down the port of an unresponsive device and powers it back up, so the camera recovers on its own.

Combo uplinkPort 17 and port 18 accept both RJ-45 and SFP, meeting a copper or fiber backbone.

Traffic priorityWRR queueing plus 802.1P and DSCP priorities put video streams ahead of management traffic.

Electrical resilienceLightning protection reaches 4 kV in common mode and 2 kV in differential mode; ESD contact discharge withstands 6 kV.

Transmission distance figures come from the Dahua test lab and serve only as reference; the actual distance varies with the power consumption of connected devices and the cable type and condition.
