Port Description

24 x 10/100/1000Base-T PoE ports (ports 1-24, PoE+ up to 25.4W each), 1 x 10/100/1000Base-T uplink port with PoE++ up to 60W (port 25), 1 x 10/100/1000Base-T uplink port (port 26), + 1 x 1000Base-X SFP slot (port 27).
  • Unmanaged 24 port gigabit PoE switch – no configuration needed, true plug-and-play for IP cameras and VoIP phones
  • 24 PoE+ ports (IEEE 802.3af/at, up to 25.4W each) plus one PoE++ port (IEEE 802.3bt, up to 60W) for high-power devices
  • DIP switch enables 250m long-distance transmission on ports 1-24 at 10Mbps – extend your network without extra hardware
  • One-key VLAN mode isolates downstream ports to reduce broadcast storms and improve security in surveillance setups
  • Digital tube displays real-time PoE power utilization – monitor load at a glance
  • Fanless metal housing with internal power supply, operates from -20°C to 60°C – reliable in demanding environments
  • Optional 6KV/4KV surge protection and AI watchdog (auto-reboot) for extra resilience









Designed for Surveillance, Built for Simplicity

If you’re deploying a camera system in a hotel, retail store, or office, you don’t want to spend hours configuring a managed switch. This unmanaged 24 port gigabit PoE switch gives you exactly what you need: reliable power over Ethernet, plug-and-play setup, and extra reach when cameras are far from the wiring closet. With 24 PoE+ ports delivering up to 25.4W per port and one dedicated PoE++ port pushing 60W for pan-tilt-zoom (PTZ) cameras or wireless access points, you can handle mixed-device environments without thinking about power budgets.

The real differentiator? A hardware DIP switch that forces ports 1–24 to 10Mbps mode, extending transmission distance up to 250 meters over standard Cat5e cable. No extra repeaters or converters – just flip the switch and your camera link stretches further. Combine that with VLAN isolation on the same switch: downstream ports can’t talk to each other, cutting broadcast storms and keeping your surveillance traffic separate from guest Wi-Fi. Upstream ports (25–27) still communicate freely with your router or NVR.

Everything runs in a fanless metal chassis rated for -20°C to 60°C, so it handles heat from PoE loads without a noisy fan. The built-in power supply keeps the footprint clean, and the digital tube on the front panel shows you real-time PoE power usage at a glance – no fancy software needed. For installations that need extra protection, optional surge protection (6KV common mode / 4KV differential mode) and AI watchdog auto-reboot are available on select batches.

This 24 port unmanaged PoE switch gigabit model is the workhorse for any small-to-medium business network that values uptime over complexity. Ship it, plug it in, connect your cameras and APs – done.
