## Overview

Dualcomm's Ethernet over Coax (DECA-100) twin pack enables a true 100Mbps Ethernet connection over existing coaxial cables up to 240 meters. This passive adapter kit is ideal for upgrading analog surveillance to IP cameras or building a high-speed home network without new wiring. Its plug-and-play design requires no power source, delivering reliable, long-distance connectivity that outperforms typical Wi-Fi setups.

## Description

Dualcomm Ethernet-over-Coax (EoC) kit includes two passive RJ45 Ethernet-to-Coax adapters (DECA-100) to enable an 100Mbps Ethernet connection over a coaxial cable with transmission distance as long as 240 meters (850 feet), which provides an extremely cost-effective solution for the two following applications： [Application #1: IP camera security surveillance system over coaxial cables] An IP camera is the state of art for today's video security surveillance systems which usually require completely new cabling by replacing the coaxial cables of analog video with twisted pair cables (e.g., Cat5e cable) for transmission of IP based video packets. By using Dualcomm's EoC adapters, an IP camera security system can be quickly set up with the pre-existing coaxial cables. The saving will be significant from otherwise the costs of new cabling and the associated labors. [Application #2: True 100Mbps home networking over in-home coax cables] Dualcomm's EoC adapters can be used to set up a local area network (LAN) in your home over the pre-existing coax cabling which provides true 100Mbps speed and reliable and long distance coverage much superior than wireless (Wi-Fi) connections. Especially, If you are a subscriber of a IPTV service provider such as AT&T U-Verse TV, the in-building coax cabling of your home will no longer used as it was originally used for distributing analog Television signals. Therefore, by using Dualcomm EoC adapters, you can quickly build a high-speed home network over otherwise unused coax cabling for distributing your digital TV signals to the TV sets as well as providing Internet connections to the computers and other Internet appliances in your home!

Review: Absolutely spectacular! Fast and easy! If only they cost half as much, they would be perfect. My main router is in the basement, where my office is, and where the cable, internet and phone wiring enters the house. Even with an awesome and expensive wireless router, the signal two floors above was a bit slow. I did not want to run an Ethernet cable either through the walls or on the outside of the house (it's just such a pain in the neck), but noticed some extra, unused coax wiring that went from the basement to the second floor. So first, I set up a satellite router in the basement just to make sure that I had everything configured correctly. Then I bought these adapters, screwed them to both ends of an existing wire, connected one end to the existing router, and connected the other end going to the satellite router. It worked instantaneously and fabulously. I never even looked to see if there were any documentation, as it was completely unnecessary. The only possible problem that I can see anyone running into would involve the satellite router. If you are plugging from the primary router directly to a PC, it seems quite foolproof to me. Oh, and the speed is outstanding, even going from PC to wireless router to RG45 cable to Dualcomm Ethernet Adapter to coax cable to the other Dualcomm Ethernet Adapter to another RG45 cable to the base router to a cable modem to the world. I am getting 45 Mbps without breaking a sweat, with no perceivable start-up lag time.
Review: Das Produkt tut genau was es soll. Vorteile: keine Stromversorgung nötig, passiver Adapter, SMA Anschluß für SAT Antennenkabel. Leider nur 100MB/s erreichbar, aber das reicht mir aus. Das ist ein echter Problemlöser für die Ethernetverkabelung, wenn kein Ethernetkabel verlegt werden kann, aber ein SAT-Antennenkabel vorhanden ist.

## Features

- Transmission distance of up to 240 meters (850 Feet). It works only with point to point connection. It will not work if there is a splitter between the two EoC adapters
- Great for migrating analog video surveillance systems to IO camera based systems
- Passive adapter for Ethernet transmission over a coaxial cable
- Great for buing a 100Mbps home network over existing in-house coax cabling

Had some coax line already running in the walls of my house. Wanted to convert it to CAT5. These did the trick. A bit pricey but sure was easier that running network cable in the walls.
