Description

A PoE budget for a whole camera system

All 24 PoE ports follow IEEE 802.3af and 802.3at, and the switch also supports 802.3bt and Dahua Hi-PoE for higher-power devices. The 240 W are shared between the connected devices. Intelligent PoE management shows consumption and lets you switch power on a single port off and on again, so a frozen camera can be rebooted without a site visit.

Who this network switch is for

Installers building a surveillance system with up to 24 IP cameras in an office, warehouse or retail space; small businesses that want access points and IP phones powered from one device; and IT staff who need a rack-mount switch in a metal housing that works from −10 to 55 °C.

Questions & answers

How many IP cameras can this switch power?

There are 24 PoE ports and a 240 W budget, which works out to 10 W per port on average with every port in use. Check your cameras' data sheets: if each draws under 10 W, all 24 can run at once.

Is it managed, and can I set up VLANs?

Yes. It is a managed L2 switch configured through a web interface or the cloud, with 32 port-based VLANs, flow control and jumbo frames.

Can it be mounted in a server rack?

Yes, the manufacturer lists rack mounting. The housing measures 440 × 220 × 44 mm and weighs 2.5 kg, and it can also sit on a desk.
