Unmanaged PoE Switch Dahua Technology SF1005P — 5x Fast Ethernet (10/100), L2, PoE, 48–57V, Black

DH-SF1005P is an unmanaged L2 PoE switch with five Fast Ethernet (10/100) RJ-45 ports designed for small networks and PoE devices such as IP cameras. It supports full-duplex transmission, a switching capacity of 1.8 Gbit/s and accepts 48–57 V DC input for PoE power. The compact, wall-mountable black enclosure provides basic switching functionality and two transmission modes to adapt to different network scenarios.

Advantages

The switch provides intelligent PoE management with real-time power monitoring and prioritisation of important ports, reducing the risk of power-related malfunctions. One orange Hi-PoE port can supply up to 60 W for high-power devices. Built-in PoE Watchdog enables automatic detection and restart of failed ports to recover IPC connections without manual intervention. The device supports extended PoE transmission up to 250 m and an 8-pin assignment on Ethernet ports to improve compatibility and reduce cable loss.

Suitable for

• Small office or home networks requiring PoE for IP cameras or access points
• Surveillance systems with a mix of standard PoE and one high-power device
• Installations needing simple unmanaged L2 switching and wall-mount deployment
• Projects that benefit from extended PoE reach (up to 250 m)

When it may not be suitable

This unmanaged switch does not provide advanced managed features such as VLAN configuration, QoS policies, SNMP monitoring or port mirroring, so it is not suitable for networks that require centralized management, fine-grained traffic control or enterprise-grade monitoring. It also does not support 10 GbE connections, so environments needing multi-gigabit uplinks should choose a different model.

Key specifications

• Ports: 5 × Fast Ethernet (10/100) RJ-45 (4 PoE ports + 1 uplink)
• PoE standards: IEEE 802.3af/802.3at plus one Hi-PoE port supporting up to 60 W output
• PoE input voltage: 48–57 V DC
• Switching capacity: 1.8 Gbit/s
• Transmission modes: Extend Mode On / Extend Mode Off
• Long-distance PoE: supports up to 250 m
• 8-pin assignment: PoE power on full 8-pin Ethernet assignment
• Working temperature: wide operating temperature range (device rated for outdoor/indoor use per manufacturer specs)

How to use

Mount the switch on a wall or place it on a flat surface near the network devices. Connect the DC power input (48–57 V) or an appropriate PoE power source, then connect IP cameras, access points or other PoE devices to the RJ-45 PoE ports. Use the uplink port for connection to your router or core switch. Configure the Extend Mode and PoE Watchdog via the device controls or web interface (if supported) to enable long-distance PoE or automatic port restart. Monitor connected devices and ensure total PoE power draw does not exceed the available power budget.

What to consider before purchase

• Required total PoE power budget versus the switch’s available power and the Hi-PoE 60 W port capabilities
• Need for managed features (VLANs, QoS, SNMP) — this device is unmanaged
• Distance from switch to powered devices if using long-distance PoE (up to 250 m supported)
• Compatibility of connected devices with 8-pin PoE assignment and supported PoE standards

Recommendations

For reliable operation, plan your PoE power budget, connect high-power devices to the orange Hi-PoE port, enable PoE Watchdog to reduce manual resets, and use quality Cat5e or Cat6 cabling for optimal PoE and data transmission.
