PoE Injector OEM POE4PG — 4-port Gigabit Power over Ethernet injector

OEM POE4PG is a 4-port Gigabit Power over Ethernet (PoE) injector that supplies data and electrical power to compatible network devices over standard Ethernet cabling. The unit provides four Gigabit RJ45 ports with PoE delivery on each port, enabling simultaneous connectivity and powering of cameras, wireless access points and VoIP phones where a PoE-capable switch is not available. The compact design simplifies installations by removing the need for separate power supplies at each device and allows existing network infrastructure to deliver both power and data.

Advantages

The injector supports four independent Gigabit Ethernet ports with integrated PoE delivery, reducing the need for additional power adapters and separate electrical wiring. It is suitable for retrofit installations and new deployments where centralized power distribution or PoE switches are not present. By combining data and power over the same cable, the unit reduces cabling complexity and installation time while maintaining standard RJ45 connectivity for straightforward integration into existing networks.

Suitable for

• IP surveillance cameras that require both network connectivity and power
• Indoor wireless access points and small Wi‑Fi AP installations
• VoIP phones and desk telephony devices compatible with PoE
• Small office and retail network segments where a PoE switch is not available

Key specifications

• Number of ports: 4 Gigabit RJ45 Ethernet ports with PoE output on each port
• Network speed: Gigabit (1000 Mbps) per port
• PoE capability: Power delivered over standard Ethernet cable to compatible devices
• Physical interface: Standard RJ45 connectors for data and power combined
• Mounting and size: Compact form factor suitable for desktop or wall-mounted installation (refer to manufacturer for exact dimensions)

How to use

Install the POE4PG injector near the network switch or router with available Gigabit uplink. Connect an Ethernet cable from the network switch to the injector's data input or uplink port, then connect powered devices to the four PoE-enabled RJ45 ports using standard Ethernet cables. Ensure the connected devices support PoE and that the total power requirements do not exceed the injector's per-port and overall power capacity. Power up the injector from its AC mains input or provided power adapter, and verify device link/activity LEDs to confirm proper connection and power delivery.

Usage recommendations

Use Category 5e or higher Ethernet cables for reliable Gigabit data rates and stable PoE delivery. Verify the power class and consumption of connected devices to avoid overloading the injector. For installations with multiple high-power devices or where centralized management is required, consider using a managed PoE switch or multiple injectors matched to the total power budget. Place the injector in a ventilated area away from direct heat sources and water exposure.
