Altronix EBRIDGE4PCRX EoC 4-Port Receiver

Overview

The Altronix EBRIDGE4PCRX is a rack-mount Ethernet over Coax (EoC) receiver designed for distributed IP security deployments where legacy coaxial infrastructure must be leveraged for IP device connectivity. This four-port receiver accepts EoC signals transmitted over standard coaxial cable and converts them back to IP Ethernet, simultaneously generating regulated power output for connected devices. The EBRIDGE4PCRX outputs 48–56 VDC PoE and PoE+ capability across all four ports, eliminating the need for separate power supplies at remote endpoints. Each port delivers 25 Mbps throughput, making it suitable for surveillance cameras, access control readers, intercoms, and other IP security devices in extended-distance installations.

This receiver requires a compatible EoC transceiver at the headend to complete the coax-to-Ethernet bridge. Its UL Listed and CE-approved design meets North American and European regulatory standards for security system deployments.

Key Features

• 4 IP Ethernet Output Ports: Each port delivers independent 25 Mbps throughput and PoE/PoE+ power generation
• PoE/PoE+ Power Output: Generates 48–56 VDC across all four ports for integrated power delivery to IP cameras, readers, and other powered devices
• Rack Mount Form Factor: Designed for integration into standard 19-inch security system racks and cabinets
• EoC Receiver Architecture: Converts EoC signals received over coaxial cable back to standard IP Ethernet; requires compatible transceiver at headend
• UL Listed & CE Approved: Meets UL and CE regulatory requirements for fire alarm and security system installations
• Extended Distance Capability: Leverages existing coaxial infrastructure to reach remote endpoints beyond standard Ethernet limitations

Integration & Compatibility

The EBRIDGE4PCRX functions as the remote receiver in an Ethernet over Coax system architecture. It must be paired with a compatible EoC transceiver installed at the headend location. The receiver accepts coax input, demodulates the EoC signal, and presents four independent Ethernet ports with integrated PoE/PoE+ output. This architecture is ideal for retrofit installations where running new twisted-pair cabling is impractical or cost-prohibitive, and existing coaxial runs can be repurposed for IP connectivity.

The four output ports operate independently, allowing mixed device types (IP cameras, access control devices, intercoms) to be powered and networked from a single receiver unit. The 48–56 VDC output is compatible with industrial-grade powered devices and eliminates intermediate power injectors at the remote site.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

I've specified the EBRIDGE4PCRX in several retrofit projects where coaxial runs already exist between a central headend and remote building wings. The ability to avoid costly re-cabling while simultaneously adding IP capability and power distribution makes this receiver a practical choice for integrators managing legacy infrastructure upgrades. The four independent ports with integrated PoE/PoE+ output streamline power management at the remote end.

Technical Highlights:

• Per-Port Throughput: 25 Mbps per port supports standard definition and moderate bitrate IP cameras, access control streams, and intercom traffic without saturation on typical security networks
• Power Integration: 48–56 VDC PoE/PoE+ output eliminates separate PSU requirements at the remote receiver location, reducing footprint and complexity
• Regulatory Compliance: UL Listed and CE marked design ensures compliance with fire alarm and security system installation codes

Deployment Considerations:

• Confirm coaxial cable run length and condition before installation; EoC performance depends on signal integrity over the coax backbone
• Verify that your headend transceiver is EoC-compatible with this receiver model to ensure proper signal handshake and power delivery
• Plan power distribution at the receiver rack; all four ports source from a single 48–56 VDC supply, so aggregate device current draw must be accounted for

For integrators consolidating distributed camera and access control networks over existing coaxial infrastructure, the EBRIDGE4PCRX delivers straightforward EoC receive functionality with built-in power generation. Specify it when coax-to-IP conversion and integrated PoE are required at a single remote endpoint.
