Fast Ethernet 24 Ports PoE++ Switch with Digital Power Meter for IP Camera Networks

When you are wiring up cameras across a hotel, retail store, or small office, power and signal distance are the first things that bite. This 24-port Fast Ethernet switch combines PoE++ capacity with a built-in digital power meter, so you can see the total PoE load right on the front panel. No laptop, no login, just glance at the display and know whether you have headroom for another camera.

The switch gives you 24 10/100Base-TX PoE ports for cameras and access points, plus two Gigabit copper uplinks and one 1000Base-X SFP slot. Port 1 supports up to 60W per IEEE 802.3bt, which matters for pan-tilt-zoom cameras, video phones, and high-consumption wireless access points. Ports 2-24 run on standard IEEE 802.3af/at and deliver up to 30W each. Since it automatically checks whether a connected device supports PoE, it will not feed power to non-PoE equipment, so a printer or legacy switch plugged in by mistake stays safe.

Built for Real Installations

Distance is another reality of video surveillance. Flip the 10M mode switch and ports 1-16 drop to 10Base-T speeds, which lets them send both power and data up to 250m over standard twisted pair. That covers long driveways, parking lots, or warehouse aisles without adding another switch or fiber run. In addition, the VLAN mode isolates ports 1-24 from each other while leaving the uplink ports open, so a broadcast storm from a faulty camera does not take down the entire network.

Everything else about the unit is for quick deployment: metal case, internal AC power supply, natural cooling, and no software configuration. Put it on a shelf, mount it on a wall, or rack it in a cabinet. The link/activity LEDs and numeric PoE power display make on-site troubleshooting straightforward. For a small business or an installer looking for a reliable, no-nonsense PoE++ network switch, this model fits the budget and the job.
