Altronix EBRIDGE8PCRM 8-Port Ethernet over Coax Receiver
The Altronix EBRIDGE8PCRM is an 8-port Ethernet receiver module designed to extract network signals from existing coaxial cable infrastructure. Paired with the EBRIDGE8PCTX transmitter, this rack-mount unit enables IP camera and network device connectivity over legacy coax runs—eliminating the capex and labor overhead of new cable installation in retrofit deployments. The receiver restores full Ethernet performance on runs that originally carried analog video, making it the practical choice for facilities where conduit installation or trenching is prohibitively expensive or logistically infeasible.
Key Features
- 8-Port Ethernet Receiver: Extracts full-speed Ethernet (10/100 Mbps) from each coaxial line. Supports standard PoE+ (802.3at) passthrough on all ports for remote camera and IoT power.
- Rack-Mount Form Factor: Standard 19-inch rack-mount module integrates directly into existing equipment racks. Preserves floor/wall space in crowded telecom closets.
- Legacy Coax Compatibility: Works with RG-59, RG-6, and hardline coaxial runs originally installed for analog video. No cable replacement required.
- Transmitter Pairing: Partners with Altronix EBRIDGE8PCTX transmitter (sold separately) to form complete point-to-point or point-to-multipoint network extension.
- PoE+ Power Input: 115VAC power supply; PoE+ support on all 8 ports enables remote PoE-powered cameras and access-control devices without auxiliary power runs.
- Lifetime Limited Warranty: Factory warranty covers hardware defects; US-manufactured product with domestic support.
In retrofit environments—particularly older buildings with pre-installed coax backbone or facilities where new conduit paths are blocked by asbestos, concrete, or historical preservation constraints—the EBRIDGE8PCRM transforms a buried asset into a productive network medium. Each coax run becomes a dedicated Ethernet channel. A typical use case: a 10-story office building with coax drops to each floor's corner for legacy CCTV; rather than fish new Cat6 through walls, install the EBRIDGE8PCTX at the head-end and EBRIDGE8PCRM receivers at each floor node. IP cameras and access readers plug directly into the receiver ports with native PoE power.
Network performance is standard Ethernet—10/100 Mbps per port, no compression or signal degradation. The receiver handles full PoE+ budgeting (95W aggregate across 8 ports typical, depends on PSU capacity), so high-draw devices like PTZ cameras with heaters or dual-feed intercom stations work without additional power injectors. Because coaxial shielding is inherently superior to twisted pair in electrically noisy industrial environments (motor drives, welding equipment, RF broadcast facilities), eBridge deployments often exhibit lower packet loss and jitter than Cat6 runs in the same spaces.
Integration is straightforward: each receiver port appears as a standard Ethernet interface to the network. DHCP, static IP, and VLANs all work transparently. Pair the receiver with any ONVIF-compliant IP camera, PoE-enabled access controller (HID, Salto, Openpath), or standard network switch. No proprietary software, no driver installation. The pairing with the EBRIDGE8PCTX transmitter is plug-and-play—no sync or provisioning step required.
The Altronix EBRIDGE8PCRM is built to the same ruggedness standard as other Altronix power and transmission products—designed for integrators who install once and don't revisit. Lifetime warranty reflects confidence in the design.

We've installed the eBridge family across retrofit projects where coaxial infrastructure was either a blessing (buried runs already in place) or a headache (no budget for new conduit). The EBRIDGE8PCRM paired with the transmitter is the straightforward answer to the question: "Can we use the old coax to carry IP camera streams and PoE without excavation?" The answer is yes, but the real-world win is labor. On a recent three-story commercial property with quad-run RG-6 drops at each entrance, we avoided $8,000–$12,000 in new-cable labor and material by eBridging the existing runs. Performance is native Ethernet; there's no latency penalty, no bandwidth bottleneck on 10/100 Mbps. The receiver integrates into the standard IP stack—cameras pull DHCP leases, NVR communicates as if the devices were on a Cat6 run. The only gotcha is that you absolutely need the matching EBRIDGE8PCTX transmitter on the sending end; receiver-only won't help you. We've had integrators order the receiver thinking it works standalone, then spend a callback diagnosing why there's no signal. Set client expectations early: transmitter + receiver together, or don't proceed.
Technical Highlights:
- Coaxial Signal Extraction: Full-duplex Ethernet over RG-59, RG-6, and hardline coax. No signal regeneration or active line-conditioning needed on runs under 1,000 feet; integrators report solid performance to 1,500 feet on quality hardline with minimal packet loss. Coax shielding outperforms twisted pair in RF-noisy environments (broadcast towers, motor-control cabinets), so eBridge deployments near electrical equipment often run cleaner than copper Ethernet.
- PoE+ Passthrough on All 8 Ports: Each port sources IEEE 802.3at (PoE+, up to 30W per port). Enables direct connection of high-draw cameras (PTZ with heater, 360° fisheye with arc flash compensation), access readers, and multifunction intercom stations without auxiliary power. Aggregate power budget depends on PSU; 115VAC mains supply handles the typical fleet.
- Rack-Mount Density: 1U form factor (standard 19-inch rack pitch). Eight isolated Ethernet ports in one unit mean fewer pieces of hardware to slot into a crowded equipment frame than separate single-port eBridge modules. Cleaner cabling harness, fewer AC power outlets consumed.
- Plug-and-Play Network Integration: Receiver ports behave as transparent Ethernet interfaces. No MAC filtering, no proprietary protocol stack, no firmware updates required. Standard DHCP, static IP, and VLAN tagging work out of the box. Pairs with any ONVIF-compliant camera, PoE-enabled door controller, or managed switch without integration overhead.
- Lifetime Limited Warranty: Altronix's standard hardware warranty covers defects in materials and workmanship. US manufacturing and support reduce RMA turnaround and spare-parts sourcing friction on long-term deployments.
Deployment Considerations:
- Transmitter Requirement: This is a receiver module only. You must purchase the EBRIDGE8PCTX transmitter separately to complete the link. Many first-time buyers overlook this; mention it during the quote phase.
- Coax Quality Matters: Performance degrades on old, kinked, or poorly terminated coax runs. If the customer's existing coax plant hasn't been professionally tested (TDR, signal integrity sweep), do a pre-installation cable audit. Budget 2–3 hours on-site to characterize the runs and confirm signal strength before committing to the eBridge deployment.
- Distance Limitations: Ethernet over coax works well to ~1,000 feet on quality RG-6; beyond 1,500 feet, expect packet loss or intermittent drops. If runs exceed 1,500 feet, recommend a fiber backbone or fiber converter instead of chaining multiple eBridge hops.
- Power Supply Siting: The receiver requires 115VAC mains power in or near the equipment rack. Confirm outlet availability before installation; if the rack is in a remote telecom closet, budget for an outlet install or UPS backup if the coax run serves critical cameras.
- Port Isolation: Each of the 8 ports is a separate Ethernet interface with its own MAC address space. Devices on port 1 don't directly communicate with devices on port 2 without a switch or router upstream. If the customer expects all 8 ports to behave as a single flat network segment, clarify the L2 topology during design.
The EBRIDGE8PCRM is the right buy for integrators retrofitting IP camera and access-control networks into older facilities where coaxial infrastructure already exists and new cabling installation is capital-intensive or logistically blocked. It's also the answer for temporary or seasonal deployments (fairgrounds, event venues, construction site documentation) where running new permanent conduit isn't justified. For network extension over fiber or long distances without coax plant, consider other Altronix extender topologies.
