Reliable 24 Port Fanless PoE Switch Built for Real-World Surveillance & SME Deployments

If you are setting up a medium-density IP camera system in a hotel, supermarket, or office, you know what matters: stable power delivery, minimal heat, and no fan noise. This 24 port fanless PoE switch delivers exactly that. With 24 10/100Base-T PoE ports (23 ports supporting IEEE802.3af/at up to 25.4W per port, and port 23 supporting PoE++ up to 60W), it automatically detects whether the connected device needs PoE, so you never worry about frying a non-PoE camera or access point.

Two Gigabit copper uplink ports and two 1000Base-X SFP slots handle traffic aggregation to your backbone or NVR. The built-in DIP switch lets you force ports 1-24 to 10M mode for up to 250-meter transmission over existing Cat5 cabling – a lifesaver for long corridors or outdoor runs where extending cable would be expensive. Plus, when VLAN mode is enabled, ports 1-24 are isolated from each other but still communicate with uplink ports, cutting down broadcast storms and improving network efficiency.

This unmanaged switch is truly plug-and-play – no CLI, no web GUI, no training needed. The metal housing and fanless design keep it running quietly in a hotel front desk or a retail back office, even in environments with dust or limited airflow. For extra protection, optional 6KV common mode / 4KV differential mode surge protection and an AI network watchdog (self-healing) are available. It’s the kind of tool that makes IT admins and small business owners sleep better.
