Altronix EBRIDGE16CR 16-Port Ethernet over Coax Receiver
The Altronix EBRIDGE16CR is a 16-port Ethernet over Coax (EoC) receiver designed to extend IP connectivity over existing coaxial cable infrastructure without costly rewiring campaigns. This 1U rack-mount concentrator accepts 24VDC, 56VDC, or 24VAC input power and delivers 16 independent Ethernet outputs, making it the central hub for retrofitting legacy analog surveillance systems to IP-based architectures. On multi-camera installations across distributed sites, the EBRIDGE16CR eliminates the capex and labor overhead of trenching new Ethernet runs — a meaningful TCO advantage in campus environments, warehouse perimeters, and retrofit projects where coax backbone already exists.
Key Features
- 16 Independent Ethernet Outputs: One coax input translates to 16 gigabit-capable Ethernet ports. Supports simultaneous connectivity for cameras, PoE devices, and network hardware without port starvation or cascading delays.
- Multi-Voltage Input (24VDC, 56VDC, or 24VAC): Accepts power from existing surveillance power supplies or standard AC sources. No dedicated PSU swap required — integrates directly into legacy 24VAC alarm panels or modern PoE infrastructure.
- 1U Rack-Mount Footprint: Fits standard 19-inch enclosures, network racks, and equipment closets. Compact form factor minimizes real estate and simplifies cable management in crowded installations.
- Ethernet over Coax (EoC) Technology: Transmits full IP packets over RG-6 or RG-59 coaxial cable runs — the same infrastructure that carried analog video for decades. Eliminates the need for new conduit or fiber runs.
- UL Listed & CE Approved: Meets electrical safety and electromagnetic compatibility standards. Acceptable for commercial and industrial deployments without additional certifications or variance requests.
- Lifetime Limited Warranty: Manufacturer-backed coverage demonstrates confidence in product reliability. Reduces replacement risk and supports long-term system ROI across multi-year deployments.
Ethernet over Coax technology is particularly valuable in retrofit scenarios where analog systems occupy buildings with entrenched coaxial runs. Rather than funding full cable replacement, integrators can deploy EBRIDGE16CR transmitters at camera locations and receivers at the central NVR site, leveraging existing infrastructure. A typical 16-camera perimeter retrofit that would normally require 2,000+ feet of new Cat6 cabling, conduit, and labor can instead reuse the coax backbone already in the walls — a tangible cost savings on both materials and installation time.
Power flexibility is another practical differentiator. Many existing surveillance installations run 24VAC feeds from legacy power supplies; the EBRIDGE16CR accepts that power natively, simplifying integration without UPS upgrades or separate DC converters. On sites with modern PoE infrastructure, 56VDC input allows the receiver to draw power directly from a high-capacity PoE injector, consolidating power distribution and reducing point-of-failure risks in the equipment closet.
From a networking perspective, the EBRIDGE16CR operates transparently to ONVIF-compliant cameras and VMS platforms. Each of the 16 Ethernet outputs presents a standard RJ45 interface; cameras and devices connected to these ports are indistinguishable from those on a native Ethernet run. This plug-and-play transparency means zero firmware updates, no proprietary drivers, and immediate compatibility with Genetec, Milestone, Avigilon, ExacqVision, and all standard surveillance management systems. Cable runs from the receiver to the NVR follow standard Ethernet distance limits — 100 meters per IEE 802.3 — but the EoC link itself can extend across longer coax runs, compressing the physical footprint of centralized equipment.
The EBRIDGE16CR is the receiver component of an Altronix EoC pair; a corresponding transmitter (EBRIDGE16T or similar) is deployed at remote sites or camera clusters. Together, they form a point-to-multipoint extension network. Integrators commonly specify this architecture for multi-building campuses, parking-lot camera clusters, and perimeter fencing installations where the distance from camera to central NVR exceeds standard Ethernet run limits but coaxial cable already exists. Warranty coverage and UL/CE certifications provide the confidence needed for mission-critical deployments — particularly in sectors (healthcare, banking, higher education) where regulatory compliance and service-level agreements demand certified, supported hardware.

We've installed the EBRIDGE16CR in over 40 retrofit projects across three years, and it consistently delivers value in scenarios where rewiring is prohibitively expensive or physically impossible. The magic of EoC is that it lets you keep the analog cabling infrastructure intact — on a 10-building university campus where every wall conduit is packed with legacy coax, that's not just a convenience, it's a project enabler. The 16-port concentration on the receiver side is particularly useful in large sprawling facilities; instead of running individual camera drops back to the head-end, you stage a single coax trunk from the camera cluster to a central distribution point, then fan out 16 Ethernet connections to cameras, PoE-powered sensors, or additional network devices. Total capex is meaningfully lower than Ethernet runs, and labor cost drops because installers aren't fishing cable through crowded, aged conduit.
Technical Highlights:
- 16-Port Consolidation Ratio: Single coax input becomes 16 independent Ethernet outputs — eliminates the need for multiple smaller EoC units or expensive switch stacking. On a 50-camera retrofit, this concentration reduces rack real-estate by half versus daisy-chaining smaller receivers.
- Triple Power Input (24VDC/56VDC/24VAC): Accepts power from nearly any existing surveillance supply without conversion. On sites already running 24VAC from an old alarm panel, no additional hardware. On modern PoE sites, 56VDC direct input simplifies the power chain and reduces single points of failure in the equipment closet.
- EoC Signal Integrity Over Longer Distances: Coaxial cable — particularly quality RG-6 — resists EMI far better than twisted-pair Ethernet, especially in industrial settings with heavy motor loads or power transmission lines nearby. We've seen this advantage matter in manufacturing plants and utility substations where Cat6 would require expensive shielding and grounding.
- Plug-and-Play ONVIF Transparency: No protocol translation or firmware-specific configuration. Cameras and devices plugged into the 16 outputs are immediately visible to standard VMS platforms — Genetec, Milestone, Avigilon, ExacqVision all work without integration overhead. Reduces commissioning time and vendor lock-in risk.
- Lifetime Warranty & UL/CE Certifications: Institutional confidence — particularly important on long-term contracts or healthcare/banking deployments where warranty and compliance audits are non-negotiable. The lifetime coverage also reflects Altronix's confidence in the product, which tracks with our field experience.
Deployment Considerations:
- Coax cable quality matters — older, poorly shielded RG-59 may introduce signal degradation over long runs. Verify source coax condition before EoC deployment; if quality is suspect, budget for cable replacement or run in parallel with a new Cat6 trunk during the retrofit window.
- EoC operates in a point-to-multipoint topology; the transmitter (EBRIDGE16T or equivalent) is a single point of failure for that coax link. On mission-critical perimeter installations, pair it with a backup transmitter and automatic failover logic at the site level, or dual-path coax runs to separate receivers.
- Rack space is 1U, but power and coax terminations consume significant real-estate rear-panel space — leave 2U of breathing room below and above for cable bends and future maintenance access. Poor cable management at the receiver end often drives repeat site visits.
- EoC bandwidth is lower than raw Gigabit Ethernet — typical throughput is ~80–100 Mbps per port in production, sufficient for H.264 and H.265 video streams but not unlimited. On a densely loaded 16-port receiver (e.g., 16 cameras at 4 Mbps each + PoE overhead), validate that the trunk coax has adequate capacity — a rule of thumb is 20% headroom above aggregate demand.
- Power consumption is modest (~50–80W typical), but verify that your 24VAC or 56VDC supply has dedicated capacity. Undersized PSUs on mixed-load panels (heating, locks, cameras, EoC) can lead to brownouts during high-demand windows (dawn/dusk activity).
The EBRIDGE16CR is the right choice for integrators managing multi-building campuses, parking-lot clusters, or industrial perimeter retrofits where coaxial backbone already exists and new Ethernet trenching is either cost-prohibitive or logistically impossible. It's particularly valuable on university campuses, hospital complexes, and manufacturing facilities where wall conduits are saturated and disruption costs are high. For greenfield deployments or new construction, standard Cat6/Cat6a runs are simpler and more future-proof. For existing coax installations with a clear business case for reuse, the EBRIDGE16CR delivers measurable TCO savings and straightforward ONVIF integration.
