The PoE Switch is an unmanaged switch equipped with a high-performance switching engine and large cache, ensuring smooth transmission of video streams. It features four DIP switches and supports PoE Watchdog, long-distance PoE, VIP port, and port isolation functions. The red port supports IEEE 802.3bt and Hi-PoE standards and can deliver up to 90 W. The device operates reliably within a temperature range of −10 °C to 55 °C and provides EMC compliance along with protection against overvoltage, overcurrent, static electricity, lightning strikes, pulses, and other types of interference.

BT 90W (Red Port)
The red ports support IEEE 802.3af, IEEE 802.3at, IEEE 802.3bt, and Hi-PoE standards with a maximum output power of up to 90 W per port, making them suitable for powering high-consumption devices.

Long Distance PoE
Each PoE port supports transmission distances of up to 250 m, meeting long-range wired transmission requirements, with bandwidth adjusted to 10 Mbps for extended reach.

PoE Watchdog
This innovative feature automatically detects port status and restarts failed ports when a connection exception occurs, enabling intelligent operation and maintenance while significantly reducing manual servicing costs.

Port Isolation
Devices connected to different ports are prevented from communicating with each other without the need for VLAN configuration. This protects data from leakage through PoE ports and isolates broadcast storms, ensuring a safer and more stable network environment.

Application Scenarios
Suitable for deployment in houses, factories, offices, and similar environments.
