Dahua HS4412-8ET-120 Managed 8-Port PoE Switch, 4 Uplinks, 120W

All eight RJ-45 ports deliver Power over Ethernet, so each connected device receives both data and power through a single network cable. That removes the need for separate power adapters at every camera or access point and keeps installations tidy. It is especially useful where devices are mounted on ceilings, walls or outdoor poles, far from a power socket, and it lets you power and reconnect equipment centrally from the switch.

Two of the eight PoE ports support 4-pair PoE (PoE++), which uses all four wire pairs in the cable to deliver more power than standard PoE. This makes them suitable for more demanding equipment, such as PTZ cameras with motors and heaters or higher-end wireless access points. The remaining ports cover everyday devices, and the whole switch works within a shared 120 W PoE budget, which you should keep in mind when planning how many power-hungry devices to connect.

The total PoE budget of 120 W is shared across all powered ports. In practice, that is enough for a typical set of IP cameras in a small shop, office or home installation, with headroom for one or two more demanding PoE++ devices. Before connecting equipment, add up the rated power draw of each device to make sure the combined load stays within the 120 W limit.

Alongside the copper ports, the switch provides four fibre uplink ports for connecting to the core network, an NVR or another switch. Fibre links can bridge longer distances than copper cabling and are not affected by electrical interference, which helps when the switch sits in a separate building or at the far end of a site. The manufacturer does not list the uplink speed or module type in the specifications provided.

As a managed Layer 2 switch, the HS4412-8ET-120 offers more control than a basic plug-and-play unmanaged model. Managed switching lets administrators configure and monitor ports rather than relying on fixed default behaviour, which is valuable for separating camera traffic and troubleshooting connections. The available management features and interface are not detailed in the specifications provided, so check Dahua's documentation for the exact functions.

The switch uses a desktop form factor and is not designed for rack mounting, so it fits on a shelf, a desk or in a small network cabinet. The Fast Ethernet (10/100 Mbps) copper ports suit IP cameras, VoIP phones and access points rather than high-bandwidth workstations. It suits installers, small businesses and home users building a compact CCTV or office network with PoE-powered devices.
