I've been working on a lot more IP video jobs lately. Some of these jobs are retrofit applications.
What I mean by that is that I'm taking out the analog cameras and putting IP video cameras. Most
of the time I am putting the new cameras onto the customer's current network, but some of the times the
cable runs are very long and there isn't a convenient point to connect into the customer's network.
I would like to find a good system for putting Ethernet over coax. It would also be nice to put the
power over coax. I have seen several different systems out there. They range from the simplest of
systems to some that even include a network switch. I was wondering if someone had the experience of
using any of these Ethernet over collect systems. Most of the jobs I'm doing are for professional
companies and am worried about using an off brand system. Any suggestions ???

Hello carlotes44
Yes, there are several different systems on the market today that allow Ethernet over coax(EOC). The one that Iam familiar with is the Etherstretch product from Nitek. I recently used it on a job and found it relatively easy to install. I chose it for a few reasons. First It required no setup. By that I mean I did not have to install any IP addresses or do any network configuration. That seems to be true with most of the units out there. Although several do require setting up switches are pushing buttons to establish communication, the Nitek did not. Also of interest to me was that most of the systems forced POE power onto the coax. This is not in keeping with the IEEE802.3 standard. I am aware of some cameras such as the panasonic outdoor domes which do not like POE power which is non-standards compliant. The model I used for my job was the EL1500C. here is a link to that unit.

I only needed to install for cameras over existing coax and that is why chose the single camera set. They do have some larger systems which actually includes a built-in layer 2 switch. I am not sure if anyone else here on the board tried one of their switches and maybe they can better comment on that product. I hope this is of some help to you. Please let us know your job works out.
