Supporting IEEE 802.3af/at/bt and Hi-PoE standards, ports 1-2 deliver up to 90W each for power-hungry devices, while ports 3-24 provide up to 30W per port — with a massive 375W total PoE budget to keep your entire system powered reliably. Enjoy extended reach with long-distance PoE transmission up to 250m (at reduced 10Mbps bandwidth), perfect for large-scale installations without extra repeaters.

Advanced smart features include:

• PoE Watchdog: Automatically detects and reboots faulty cameras for minimal downtime and reduced maintenance
• VIP Ports: Prioritizes traffic on ports 1-8 for critical video feeds
• Port Isolation: Prevents device-to-device communication for enhanced security and storm protection
• Built-in protections: 6kV contact/8kV air ESD, 4kV common/2kV differential lightning surge resistance
• 4 DIP switches for easy mode selection (PoE watchdog, long distance, VIP, isolation)

With a 56 Gbps switching capacity, 41.66 Mpps forwarding rate, and 4 Mbit buffer, it ensures lag-free Gigabit performance. Operates from -10°C to +55°C, features a sturdy sheet metal case, and supports rack or desktop installation.
