When You Need Simple, Reliable Power Over Long Distances
An 8 port passive PoE switch like the SL820NP is built for environments where standard PoE won’t cut it – think legacy IP cameras, older access points, or custom voltage requirements. This unmanaged switch delivers data and power over a single Cat5e/6 cable, supporting 12V or 24V output per port (pin 4/5+ and 7/8-). That means you can match the exact voltage your powered device needs without worrying about negotiation handshakes.
What sets this 8 port passive PoE switch apart is its ability to push 10Mbps signals up to 250 meters via a DIP switch. In long-range mode, ports 1-8 are isolated from each other but still communicate with the uplink ports, effectively cutting broadcast storms and collision domains. For a security installer running cameras across a warehouse floor or a parking lot, that extra distance often means fewer intermediate switches and lower cabling costs.
The switch also offers one-click VLAN mode, which separates PoE ports from each other while keeping them connected to the uplink. This is a practical way to segment traffic without configuring a managed switch – handy for small office networks or retail stores where you want to isolate guest Wi-Fi from CCTV traffic.
Who uses this 8 port passive PoE switch most? IT admins migrating legacy 12V cameras to a centralized network, small business owners setting up a simple surveillance system, and field techs who need a rugged, fanless switch that works in -20°C to +60°C environments. The metal housing and external power adapter keep heat under control, and the 5.6Gbps backplane ensures no bottlenecks when all ports are active.
- Compatible with 12V and 24V passive PoE devices – check your camera or AP specs before connecting
- DIP switch toggles between normal 100m mode and 250m long-range (10Mbps) mode
- VLAN isolation prevents broadcast loops and improves network stability
- Plug-and-play setup: no configuration required, just connect and power on
