Altronix EBRIDGE1CRT Single Port Ethernet Over Coax Adapter

Altronix EBRIDGE1CRT Ethernet over Coax Single Port Adapter Kit

Overview

The Altronix EBRIDGE1CRT is a complete Ethernet over Coax (EoC) adapter solution designed for security integrators and installation professionals who need to extend network connectivity over existing coaxial cabling infrastructure. This kit includes both receiver and transceiver units, enabling bidirectional data transmission at up to 25Mbps alongside simultaneous composite video on the same coax line. The EBRIDGE1CRT operates across distances up to 100 meters, making it ideal for retrofit deployments where running new Ethernet cabling is impractical or cost-prohibitive.

Key Features

• 25Mbps Ethernet Throughput: Sufficient bandwidth for HD video streams, PTZ camera control, and dual-direction IP communication over existing coax infrastructure
• Simultaneous Composite Video Support: Transmits analog composite video and Ethernet data on the same coaxial cable without cross-interference, preserving legacy analog installations
• Extended Range Coverage: Reaches 100 meters over standard RG-59 or RG-6 coax, eliminating the need for supplementary cabling in large facility deployments
• Flexible Power Input Options: Accepts 12VDC, 24VDC, or 16/24VAC input, allowing integration with existing power distribution systems and UPS configurations
• Complete Kit Configuration: Paired receiver and transceiver units reduce ordering complexity and ensure field compatibility without separate procurement
• Regulatory Compliance: UL Listed and CE marked, meeting North American and European safety and EMC standards required for commercial security deployments

Integration & Compatibility

The EBRIDGE1CRT functions as a transparent Ethernet bridge, connecting IP security cameras, access control readers, and network devices to PoE switches or NVRs located in central equipment rooms. The simultaneous video capability makes it particularly valuable in mixed analog-IP migration scenarios, where operators maintain existing analog camera feeds while introducing network-based devices on the same coax runs. Single-port design simplifies installation on individual camera drops or branch circuits, and the included transceiver/receiver pair eliminates field guesswork regarding unit orientation.

Package Contents

Kit includes one transceiver unit, one receiver unit, and all necessary interconnect components for immediate deployment. Both units feature F-type coax connectors and terminal block power inputs, compatible with standard security system wiring practices.

James Everett

I've specified the Altronix EBRIDGE1CRT on several retrofit projects where running new Ethernet to remote camera locations wasn't feasible. The kit's ability to carry simultaneous analog video and IP data on one coax line significantly reduces truck rolls and material costs during phased digital migrations. The 100-meter range covers most building sections without requiring intermediate repeaters.

Technical Highlights:

• Dual-Mode Transmission: The EBRIDGE1CRT transmits 25Mbps Ethernet alongside composite video, letting you operate legacy analog monitoring systems while rolling out network cameras incrementally
• Power Flexibility: Input options for 12/24VDC and 16/24VAC allow direct connection to existing security power supplies, eliminating dedicated adapters

Deployment Considerations:

• Verify coax cable condition before installation — existing RG-59 runs may exhibit higher attenuation; RG-6 is recommended for maximum range and signal integrity
• Position power supplies near transceiver units to minimize voltage drop over long terminal runs and ensure stable 25Mbps operation

The EBRIDGE1CRT is a straightforward, standards-based solution for extending network reach without infrastructure overhaul. Its UL and CE approvals streamline approval for commercial and institutional contracts. Pair it with PoE switches for a complete edge-to-core deployment strategy.
