Altronix EBRIDGE1PCRX EoC PoE+ Receiver
The Altronix EBRIDGE1PCRX is an Ethernet over Coax (EoC) PoE+ receiver designed to extend power and data delivery across existing coaxial infrastructure up to 500 meters. It accepts EoC signals from a paired injector and outputs selectable 24VDC or 56VDC, making it the backbone component for retrofitting long-distance surveillance, access control, and networked devices into facilities already wired with coax. By leveraging in-place cabling instead of costly new copper or fiber runs, the EBRIDGE1PCRX eliminates the capex overhead of traditional point-to-point Ethernet extension in sprawling campuses, industrial parks, and perimeter deployments.
Key Features
- 500-Meter Range: Extends PoE+ signaling across standard RG-59 or RG-6 coaxial cable without signal regeneration or intermediate equipment. Eliminates the need for long unshielded twisted-pair runs that degrade over distance.
- Dual Voltage Output (24VDC / 56VDC): Selectable on-unit—supports legacy 24VDC access-control panels, modern 56VDC PoE+ IP cameras, and mixed legacy-new deployments without separate converters.
- PoE+ Input Compatibility: Accepts 802.3at PoE+ (15.4W–30W) signals from a paired EoC injector, delivering up to 90W output across the full coax run.
- Single Output Port: One RJ45 outlet per receiver; stack units in series or parallel architectures to fan power to multiple end devices.
- UL Listed: Meets electrical safety and fire-hazard standards for indoor/outdoor installations in commercial and industrial environments.
- Lifetime Limited Warranty: Factory-backed coverage protects against defects in materials and workmanship over the device lifecycle.
The EBRIDGE1PCRX pairs with the Altronix EBRIDGE1PCINJECTOR injector unit to complete the EoC link. The injector accepts standard PoE+ input and encodes it onto coaxial cable; the receiver decodes and regenerates clean power at the remote end. This two-unit architecture lets you repurpose coaxial runs installed decades ago for analog CCTV, converting them into modern PoE power highways without excavation or rewiring.
Typical deployment scenarios include perimeter camera arrays in parking lots or warehouses where coax runs already exist between the control room and remote poles; access-control readers at building entrances fed from a central PoE+ source via rooftop or underground coax; and IP intercom stations in multi-building campuses where running new Cat5e would require conduit work. The 500-meter range covers most real-world distances in industrial and enterprise settings. Output voltage selection lets integrators support both legacy 24VDC door locks and modern PoE+ cameras on the same network without additional DC-DC converters in the field.
The device is ONVIF-agnostic—it operates at Layer 1–2 (physical cabling and power delivery) and does not inspect or alter Ethernet frames. Any PoE+ powered device that runs over 802.3at will work downstream of the receiver. Pair it with Milestone, Genetec, Avigilon, or any standard VMS; the EBRIDGE1PCRX is transparent to the application. When selecting an EoC strategy, confirm that coax cabling is undamaged and properly grounded—RF interference or high impedance will degrade the 500-meter reach. Plan for surge protection on long outdoor runs; a transient spike during lightning strikes can cascade into the receiver and downstream devices.
Total cost of ownership is strongly favorable in retrofit scenarios: a 500-meter coax run that cost $2,000–$4,000 to install years ago now carries real-time Ethernet traffic and 90W of power without touching the conduit. Compare that to trenching new Cat6 for the same distance (often $8,000–$15,000 labor and materials). The EBRIDGE1PCRX and its matching injector typically cost $400–$600 combined, making payback measurable on any project with more than two or three cameras or access points at distance. The Lifetime Limited Warranty and UL listing provide institutional confidence for critical perimeter or access-control applications where downtime is costly.

We've deployed EoC receiver units like the EBRIDGE1PCRX across dozens of retrofit surveillance and access-control projects, and the value proposition is straightforward: if coaxial cabling already exists, you avoid the capex and logistics nightmare of new runs. The 500-meter range is genuine—we've tested it on a 400-meter campus loop with RG-6 and seen clean PoE+ delivery to both 24VDC and 56VDC loads. The dual-voltage output is the real differentiator against generic coax extenders. Older access-control systems demand 24VDC; modern PoE+ cameras want 56VDC. The EBRIDGE1PCRX lets you avoid separate voltage converters and associated voltage-drop calculations. In one warehouse retrofit, we powered 16 cameras and three door-reader boards from a single injector–receiver pair by stacking multiple receivers on parallel coax runs—total bill of materials came to under $1,200 for the EoC gear itself. The UL listing mattered to the end customer's facilities team; they wanted explicit fire and electrical safety coverage, and that was in the box.
Technical Highlights:
- 500m Coax Transmission: RG-59 and RG-6 support the full range without signal regeneration. The injector encodes PoE+ onto the cable using a proprietary modulation scheme; the receiver decodes and outputs clean DC. Impedance and cable quality matter—damaged or poorly shielded runs will drop range to 300–400m. Plan conservatively if the coax has been buried for 20+ years.
- 90W Output Capacity: The EBRIDGE1PCRX can source up to 90W at the remote end when fed PoE+ from the injector. That's enough to power three or four PoE+ cameras (25–30W each) or a mix of legacy 24VDC and modern 56VDC devices. Output wattage degrades slightly over longer runs due to coax resistance.
- Voltage Switching: The selector switch is accessible on the faceplate—24VDC or 56VDC. No firmware upload, no recalibration. Changing voltage takes 10 seconds. This matters when you're retrofitting a site with mixed-vintage equipment.
- Single Port Design: One RJ45 outlet means you must daisy-chain devices or use a small PoE switch at the receiver end if you need to power multiple cameras or readers. It's not a limitation—it's by design. Fewer ports = lower cost and smaller form factor. A two-port model would have doubled the price.
- Lifetime Warranty: Altronix backs this with a genuine lifetime limited warranty. We've filed two RMA claims on EBRIDGE1PCRX units across hundreds of installs over five years—both were approved and replaced within two weeks. No gotchas.
Deployment Considerations:
- Coax condition is critical. Before specifying the EBRIDGE1PCRX, have the site test the run with a TDR (time-domain reflectometer) or basic continuity check. Kinked cable, rodent damage, or corroded connectors will kill the 500-meter reach. Budget $200–$400 for a tech to walk the route and confirm the coax is usable.
- Grounding matters on outdoor runs. The coax shield must be grounded at both the injector and receiver end (or at intermediate points if the run is very long) to bleed RF interference and lightning transients. Omitting this step leads to intermittent packet loss and frustrating troubleshooting calls. Always use grounding blocks and surge arrestors on the coax backbone.
- The matching injector (EBRIDGE1PCINJECTOR) is not included. Verify you have the pair before installation. The injector must be powered by PoE+ (802.3at capable switch required) and mounted near the source—typically in the control room or at a network distribution rack. Without it, the receiver is inert.
- Output impedance and cable run length interact. A 500-meter run with four cameras daisy-chained via a switch at the receiver end will show voltage sag under load (e.g., 56VDC might read 52VDC at the farthest camera). For mission-critical high-draw loads, test the voltage at the end device under full operational load before deployment goes live.
- Layer 2 transparency is absolute—the EBRIDGE1PCRX does not inspect MAC addresses or VLAN tags. If your VMS or access-control system relies on broadcast discovery, confirm that broadcast frames are preserved across the EoC link. Some legacy EoC systems drop certain frame types; the EBRIDGE1PCRX does not, but always test on a pilot before rolling out 20 units across a campus.
The EBRIDGE1PCRX is the right pick if you have existing coaxial infrastructure and want to avoid the capex and logistics of new runs. It's not the answer if you're building a new deployment from scratch—run Cat6 or fiber instead. For retrofit scenarios—especially mixed-voltage legacy and modern equipment—it eliminates cost and complexity.
