This article covers QAWIHTFURD PoE Over Coax EOCコンバーター.
Overview
The QAWIHTFURD PoE Over Coax EOC Converter is a specialized networking device that enables simultaneous power and data transmission over standard RG59 coaxial cable up to 3000 feet (approximately 914 meters). This product is ideal for extending IP networks to remote locations without the need for new Ethernet cabling, leveraging existing coaxial infrastructure commonly found in older buildings, warehouses, and surveillance systems. Its hybrid plastic-and-metal housing ensures durability and adequate heat dissipation for continuous operation. Using EOC (Ethernet over Coax) technology, this converter multiplexes Ethernet signals and PoE power onto a single coaxial line. This allows for a seamless migration from analog CCTV systems to IP-based surveillance, or extending network access to outbuildings and remote equipment rooms. The plug-and-play design means minimal configuration is required, making it accessible even for users with limited networking experience.
Key Features
Long-distance transmission up to 3000 feet: Using standard RG59 coaxial cable, the converter can deliver both power and data over distances up to 914 meters, perfect for remote IP cameras or wireless access points. PoE power delivery: The unit supplies Power over Ethernet (PoE) through the coaxial cable, eliminating the need for separate power outlets at the remote device location and reducing installation complexity. Plug-and-play setup: No software or complex configuration is needed. Simply connect the transmitter and receiver units with coaxial cable and Ethernet cables, and the network link is established automatically. Rugged construction: The combination of plastic and metal materials provides a balance of lightweight design and structural integrity, suitable for both indoor and outdoor use in demanding environments. * Utilizes existing cabling: By reusing existing coaxial wiring, this converter saves significant time and cost compared to pulling new Ethernet cables, especially in finished buildings or large facilities.
Connectivity & Compatibility
The QAWIHTFURD converter works with standard RG59 coaxial cable (75 ohm) terminated with BNC connectors. It operates as a pair: the transmitter connects to a network switch or PoE injector via an RJ45 Ethernet port, and the receiver connects to a PoE-compatible device such as an IP camera or wireless access point. The Ethernet interface supports 10/100BASE-TX, providing up to 100 Mbps throughput. PoE compatibility includes IEEE 802.3af (up to 15.4W) and 802.3at (up to 30W), depending on the power source and cable quality. Note that actual performance may vary based on cable length, quality, and environmental factors; real-world testing is recommended before full deployment.
Product Info
As of May 2026, the QAWIHTFURD PoE Over Coax EOC Converter is available on with a price range of approximately 5,000 to 8,000 JPY. The manufacturer's warranty period is not explicitly stated, but typical import products offer a 30-day initial defect coverage. The package includes two units (transmitter and receiver), power adapters, and a quick-start guide. Coaxial cables and BNC connectors must be purchased separately. Availability is primarily through online retailers such as , with limited stock at specialized networking stores.
Best Use Cases
Upgrading analog CCTV systems to IP surveillance: If your building already has coaxial cabling for analog cameras, this converter allows you to replace them with PoE IP cameras without rewiring, saving both time and labor costs. Extending network to remote buildings or outdoor equipment: For warehouses, factories, or campus environments where running new Ethernet is impractical, the 3000-foot range enables reliable connectivity to distant devices. * Deploying network in older or historic buildings: In structures where drilling or cable management is restricted, existing coaxial lines provide a ready-made pathway for IP networking, making this converter an ideal solution.
