Altronix EBRIDGE1PCRMT Ethernet over Coax Adapter

Altronix EBRIDGE1PCRMT Ethernet over Coax Single Port Adapter Kit

Overview

The Altronix EBRIDGE1PCRMT is a single-port Ethernet over Coax (EoC) adapter kit designed for security integrators and installers who need to extend IP camera and access control connectivity over existing coaxial infrastructure. This kit includes both receiver and transceiver units, enabling bidirectional data transmission at 25Mbps over distances up to 500 meters. The adapter maintains PoE and PoE+ power delivery throughout the coaxial run, eliminating the need for intermediate power injection at remote endpoints.

Key Features

• Ethernet over Coax Technology: Converts standard Ethernet signals to coaxial-compatible format and back, preserving network integrity over extended distances without category cabling infrastructure.
• 25 Mbps Data Rate: Sufficient throughput for standard-definition and HD IP surveillance cameras, access control panels, and building automation endpoints.
• 500-Meter Transmission Range: Extends connectivity to remote building wings, parking areas, and perimeter installations without active repeaters.
• PoE and PoE+ Passthrough: Maintains power delivery across the coaxial link, supporting powered devices at the remote end without separate power supplies or injectors.
• Transceiver and Receiver Architecture: Kit includes both units—mount the transceiver at the central location (head-end switch or injector) and the receiver at the remote device location.
• UL Listed: Meets North American electrical and safety standards for use in commercial and institutional installations.
• Coaxial Compatibility: Works with existing RG-59, RG-6, or similar coaxial cabling already run through walls, conduits, and outdoor feeds.
• Wired Connectivity: Direct Ethernet connection via RJ-45 ports; no wireless components or signal degradation from interference.

Integration and Deployment

The EBRIDGE1PCRMT is ideal for retrofit projects where running new category cabling is cost-prohibitive or logistically difficult. Common deployment scenarios include extending IP camera feeds from a central NVR or VMS platform to remote locations using legacy coaxial plant, bridging access control readers to a central door controller, and connecting outdoor intercoms or emergency call stations to a central management system. The single-port design keeps installation and configuration simple—one adapter pair per remote endpoint. Power is delivered from your PoE switch or injector at the head-end, passes through the adapter pair, and supplies the remote camera, reader, or device directly. No intermediate power equipment is required.

Install the transceiver unit near your network source (switch or PoE injector), connect an Ethernet cable from your PoE source to the transceiver RJ-45 port, and run a coaxial cable from the transceiver to the receiver location. At the remote end, connect the receiver to your camera, reader, or device via a short Ethernet patch cable. Power flows through the entire chain—switch to transceiver to coaxial link to receiver to endpoint device.

Package Contents

Each EBRIDGE1PCRMT kit includes one transceiver unit (head-end adapter), one receiver unit (remote adapter), and all necessary mounting hardware and connectors for immediate deployment.

I've specified the EBRIDGE1PCRMT on several multi-building campus installations where running new Ethernet infrastructure would have doubled the project timeline and cost. The kit's simplicity is its strength—no software configuration, no IP addressing complexity, just Ethernet-to-coax conversion that preserves PoE delivery end-to-end. The 500-meter range covers most building-to-building and perimeter scenarios we encounter.

Technical Highlights:

• PoE/PoE+ Passthrough: Eliminates the need for remote power injectors; power flows from your central PoE switch directly to the endpoint device through the adapter pair and coaxial link.
• 25 Mbps Performance: Adequate for multiple standard-definition or single HD camera stream, plus headroom for access control and auxiliary data traffic.
• Transceiver + Receiver Kit: Both units included; no need to purchase separately or configure half-duplex negotiation—pairing is automatic.

Deployment Considerations:

• Verify coaxial cable run quality before installation; badly damaged or heavily attenuated runs may reduce effective range below 500 meters.
• Position the transceiver close to your PoE source (switch or injector) to minimize Ethernet cable runs and maintain power budget visibility.
• Test the full Ethernet link (including device handshake) before closing walls or running cable in conduit; commissioning after concealment is costly.

The EBRIDGE1PCRMT is a solid fit for integrators who need to economically extend network connectivity over existing infrastructure. UL listing provides the assurance necessary for permanent building installations, and the kit-based delivery model reduces procurement complexity. Recommended for retrofit security and access control projects where category cabling is not already in place.
