DH-PFT3485
System Overview
The Device is a hardened PoE extender. It works together with conventional PoE devices to extend their maximum base transmission distance to 350 meters.
Functions
PoE Input
Gigabit PoE input and 100 Mbps PoE output, just one cable satisfies demand of power supply and signal transmission.
Long Distance PoE
By dialing or enabling long-range transmission on the WEB interface, the transmission distance of a PoE port can be up to 250 m, meeting the requirement of wired transmission (bandwidth reduced to 10 Mbps).
Red Port 90W
The red ports support IEEE802.3af, IEEE802.3at, IEEE802.3bt and Hi-PoE standards. Suitable for powering high-power devices.
PoE Watchdog
Adopts the innovative PoE Watchdog. PoE Watchdog can be switched on by dialing/turning on the WEB page switch. It enables the switch to automatically detect port status and restart the failed ports to recover connection in case of IPC connection exception. This enables intelligent operation and maintenance management in its true sense and effectively reduces manual maintenance costs.
- 4× 100 Mbps PoE Ethernet ports, 1 × 1000 Mbps PoE Ethernet port.
- All ports meet the requirements of IEEE802.3af and IEEE802.3at standards. The red ports also conform with Hi-PoE and IEEE802.3bt standards.
- 250 m long-distance PoE transmission, which can be enabled by the DIP switch.
- PoE Watchdog for real-time detection of terminal device status.
- Fanless.
- Full-metal.
- Lightning Protection: common mode: 4 kV, differential mode: 2 kV.
- Desktop mount and DIN-rail mount.
Wide Operating Temperature
Supports working at ambient temperatures of –30 °C to +65 °C and has built-in professional mine-proof circuits, effectively reducing the impact of thunderstorms on network systems and improving system robustness, adapted to harsh environments.
Full Metal Design
With a full-metal design, the device features a durable casing and provides excellent heat dissipation to ensure its performance in a harsh environment.
Scene
It designed for different surveillance scenarios such as roads in parks/communities, malls, medium to large factories, and construction sites.
