Using IP cameras on existing coaxial / analog wrg59 or rg6 cable
Posted by José A. Noy at Friday, November 13, 2009MX-2Wire MX 2-Wire Copper Connection
1. Product Description
The Mx2wire will be a complete new category of MX product and allows to develop new market segments and applications.
Main objective is to connect MX cameras or other PoE or NON-PoE devices through a 2- wire copper connection. This is extremely interesting to re-use existing copper wires like antenna coax, telephone or power cables. With this device you can retro-fit older buildings, replace analog installations, extend networking to other rooms and installation sites with very low installation effort. Mx2wire is only working as pair. See system diagram:
Important Notice: MX-2Wire is only working as a set of 2 devices and therefore will be only delivered as set of 2. You can not mix Mx2wire with other Ethernet modulators.
2. Major Product Advantages
Mx2wire transports data and power according to PoE standard
Mx2wire does not require separate power supply
Mx2wire uses existing telephone, power or antenna coax cables and cuts down tremendously the time and effort for installations
Mx2wire converts an existing 2 wire line into a modern multi-media-line - quick, easy and inexpensive.
Mx2wire is a quality product made in Germany: R&D and Production done 100% in Germany
3. Major Product Features USPs (Unique Sales Proposition)
Transmission of Ethernet connectivity and PoE via 2 wire
Easy connection of 10/100 Mbit Ethernet-devices
Replaces cost- and time intensive installation of network cabling
Connection to PC, WLAN DSL-router, IP-camera, IP-telephone, IP-door unit, etc.
Connected devices can be powered up to 7 Watt via PoE
Ideal, when wireless connections are not possible (due to distance to transmitter, wall thickness, etc.)
Data transmission of up to 500m, data rate (depending on distance) up to 15Mbit/s net
Easy installation in standard electrical sockets (surface and in-wall mount) developed, manufactured and patented by MOBOTIX in Germany
Two LEDs indicating connectivity and power status
Power supply of Mx2wire via one single standard-PoE-switch
4. Power and Bandwidth - Distance Performance
Mx2wire always starts as a class 0 device and powers PoE devices up to 7 Watt (Class2). This is the max. power available of PoE devices. However, the final power, arriving at the PoE device is depending on the length, type and quality of the used cable. Due to Physics, especially when the used cable is too long, only data can be transported but not any guaranteed power level according to PoE anymore. Therefore, we have made some measurements with different cable types, in order to give customers guidelines what can be expected under “normal” circumstances. In these cases when the cable is too long, you will read in the table at max. transported PoE power N.A. However, as MX cameras are only requiring 3 Watt, this is sometimes sufficient to power a camera, but has to be tested on case by case.

Retail
Chain stores, individual stores, department stores, discounter chains, gas station shops, convenience stores, banks, fast food chains, coffee shops, etc.


When they work, they work really well, but you will often find that old wiring has a lot of ghosts lurking in it. Things thing poor splice jobs, taps that are not obvious at first and corrosion at junction blocks can really massively degrade the throughput.
If you're going to be using these sorts of devices for IP video, it can be helpful to run a simple iperf (or similar) test between two devices at the endpoints to see what kind of throughput you can reasonably expect.
I have an Asus EEE netbook that is handy for being one end of a network throughput or connectivity test.
Great insight. I appreciate bringing in the point of testing cables. We have run on this issue many times before. Testing the cable can relieve you from much head ache.
We published this particular conversion kit due to the fact that it works very well with our Mobotix camera line.
