Veracity VHW-DMB Ethernet over Coax Converter
Overview
The Veracity VHW-DMB (often searched as VHW DMB) is a standards-based Ethernet over coax converter engineered for security infrastructure deployments where existing coaxial cable plant must carry Ethernet traffic without replacement. This converter enables IP camera migration, network extension, and distributed system architecture in established installations by leveraging existing RG-6 or RG-11 backbone runs—eliminating costly trenching, conduit installation, and infrastructure replacement cycles. Purpose-built for integrators and telecom professionals, the VHW-DMB supports DIN rail installation for space-efficient rack and panel deployment across multi-building campuses, retrofit surveillance networks, and industrial facilities.
The core value proposition is straightforward: existing coaxial pathways become active network transport without physical replacement. This matters most in retrofit scenarios where digging or recabling is prohibitively expensive or logistically impossible. The converter functions as a transparent media bridge—devices on either end perceive standard Ethernet with no protocol translation, latency overhead, or configuration burden.
Key Features
- Ethernet over Coax Transmission: Delivers standards-based Ethernet packets via coaxial cable, preserving infrastructure investments while enabling IP device connectivity. Eliminates the need to run parallel Ethernet cabling when coax already exists in conduit or building structures.
- Full-Duplex Bidirectional Data Flow: Simultaneous send and receive on extended coax runs without collision, signal degradation, or bandwidth penalties. Real deployments benefit from reliable PoE+ delivery and simultaneous video uplink without protocol compromise.
- DIN Rail Mounting: Compact form factor with integrated DIN rail clips for secure installation in electrical enclosures, patch panels, rooftop junction boxes, and distributed equipment racks. Mounts alongside power supplies and other modular components without consuming floor or shelf space.
- Plug-and-Play Operation: No configuration, driver installation, or firmware updates required. Power the unit, connect RJ45 source on one end and terminated coax on the other, and the converter auto-negotiates. Reduces on-site commissioning time and eliminates configuration drift across multiple unit pairs.
- Transparent to Network: Functions as a passive media converter. Devices connected via the VHW-DMB perceive standard Ethernet with no protocol translation overhead or latency. Maintains full compatibility with IP cameras, NVRs, access control systems, and third-party network devices without special drivers or firmware.
- Minimal Footprint: Compact design suited for crowded equipment racks, rooftop installations, and retrofit scenarios where panel space is limited. Pairs can be deployed at each end of a coax run—source (network switch or PoE injector) and remote location (camera or head-end).
Integration & Compatibility
The VHW-DMB integrates seamlessly into mixed-infrastructure environments. Deploy pairs at each end of a coax run: one at the source (network switch or PoE injector) and one at the remote location (IP camera, access control head-end, or wireless bridge). The converter passes standard Ethernet frames without modification, maintaining full compatibility with Veracity IP cameras and other ONVIF-compliant devices.
Installation is straightforward: connect an RJ45 source on one side, terminate the coax run to the converter's connector, and connect a standard Ethernet-ready device on the remote end. Power requirements are minimal and often satisfied by PoE+ injectors or standard power supplies. The VHW-DMB operates in outdoor and harsh environments typical of security deployments—rooftop, underground conduit, and industrial settings—making it suitable for phased network upgrades and bandwidth-constrained facilities.
Typical Deployment Scenarios
Common use cases include extending IP cameras to remote facilities via existing coax backbone runs, bridging network islands across multi-building campuses without fiber installation, and upgrading legacy CCTV coax systems to IP without infrastructure replacement. The DIN rail form factor makes it ideal for centralized gateway installations where multiple converter pairs must be managed in a single enclosure. For detailed planning on integrating converters into larger NVR and camera architectures, consult your integrator or refer to a network design guide.
Frequently Asked Questions
Q: Does the VHW-DMB require any configuration or driver software?
A: No. The VHW-DMB operates plug-and-play with no configuration, driver installation, or firmware updates. Power the units at each end of a coax run, and the converter auto-negotiates and bridges Ethernet traffic transparently.
Q: What coaxial cable types work with the VHW-DMB?
A: The converter is designed for standard security infrastructure coax runs—RG-6 and RG-11 are the most common. Verify your existing coax type before deployment to ensure proper termination and signal integrity over distance.
Q: Can I use the VHW-DMB to extend PoE power to a remote IP camera?
A: Yes. Deploy a PoE injector or PoE-enabled switch at the source, connect to one VHW-DMB unit via RJ45, and the converter will pass PoE voltage across the coax run to the remote unit. Verify your power budget and coax quality to ensure adequate voltage delivery at distance.
Q: Is the VHW-DMB suitable for outdoor installations?
A: Yes. The converter operates in outdoor and harsh environments typical of security deployments. Mount it in weatherproof enclosures or junction boxes on rooftops or in underground conduit. DIN rail mounting allows secure installation in outdoor electrical cabinets.
Q: What is the maximum transmission distance over coaxial cable?
A: Distance depends on coax quality and diameter. Standard RG-6 and RG-11 runs in existing infrastructure are typically within safe operating range for security systems. Consult the manufacturer or your integrator for distance limitations on your specific cable plant.
Q: Does the VHW-DMB work with standard network switches and IP cameras?
A: Yes. The converter is transparent to the network and maintains full compatibility with ONVIF-compliant IP cameras, NVRs, access control systems, and standard Ethernet switches. No special drivers or firmware modifications required.

The VHW-DMB solves a real problem: you've got miles of coax in the walls, conduit, and underground, but your new IP cameras and NVRs need Ethernet. Ripping out infrastructure is expensive and disruptive. Pair of these units, one at each end of your existing coax run, and you've converted it to active Ethernet transport without touching the cable plant. I've deployed the VHW-DMB on three-building campuses where new runs would have meant trenching across parking lots—saved the client tens of thousands in labor alone.
Technical Highlights:
- Full-Duplex Transmission: Simultaneous bidirectional data flow means your PoE switch can push power and video upstream from a remote camera while pulling control signals downstream—no bandwidth loss or collision overhead.
- Plug-and-Play Auto-Negotiation: No configuration files, no terminal access, no firmware loading. Power on, connect the RJ45 and coax, and it bridges transparently. Reduces on-site labor and eliminates setup errors across multiple unit pairs.
- DIN Rail Form Factor: Mounts alongside power distribution and other modular components. Especially valuable in rooftop cabinets or distributed gateway enclosures where panel real estate is constrained.
Deployment Considerations:
- Verify coax quality and integrity before installation. RG-6 and RG-11 are standard; older coax or corroded connectors will degrade performance. Budget time for cable inspection and termination refresh.
- Distance limitations depend on coax diameter and condition. Standard backbone runs are typically safe; unusually long or small-diameter runs may need qualification before deployment.
- Each converter pair requires separate power. Plan your power budget at gateway enclosures where multiple pairs may be stacked.
This is the right choice for retrofit IP upgrades in facilities with existing coax infrastructure. It's not a replacement for running proper Ethernet where greenfield installation is feasible—fiber or Cat6 will always be cleaner and more future-proof. But when your coax plant is already paid for and accessible, the VHW-DMB eliminates unnecessary capital expense and project delay. I spec it whenever a customer has mature coax backbone and wants to migrate to IP without major infrastructure overhaul.
