Review on Dualcomm POE Over Coax Adapter Kit DECA 200 by Kenneth Cotton

This is a very elegant solution when you need to use a POE camera (or other POE device) with traditional coaxial cabling. If you have a 4-wire ethernet interface to your camera (Doorbird), you will need to contact the company for a DECA-Mode A kit for DECA-Mode A. If you have any problem with the product, do not hesitate to send an email to Dualcomm immediately. I did it on Saturday and the inventor of the device replied within 2 hours. Two emails later, the problem was identified as the Doorbird camera I was using had a 4-wire (non-standard) Ethernet interface versus the nominal 8-wire. The solution was to replace the DECA Mode B block with a DECA Mode A block (the company did so, no questions asked). It worked great because the right configuration was set.
