LINOVISION POE Over Coax EOC Converter IP Over Coax Max 3000ft Power and Data Transmission Over Regular RG59 Coaxial Cable for Upgrading Analog Surveillance System to IP Surveillance System

Works great, the larger gauge wire you use the better it works. I used 14guage and went over 500ft

I own a company providing IT, Automation, and Camera systems for large homes here in Texas and I was skeptical when I saw these. The way of the world is IP cameras but a job we were bidding on was wired with the old RG59 with 16/2 siamese type cable and it would have been impossible and costly to run new wire. Of course, the client wanted the latest and greatest IP-type cameras to use with the automation system we were putting in, so I started searching. I found these and could not believe that one, how inexpensive they were, and 2, they actually solve a HUGE issue in our industry. So I bought a set to test at our shop and low and behold they were literally plug and play. So I bid the job with them specified and it went off without a hitch. Whats even more amazing is they include two adapters in the kit that just have two screww terminals markets + and - on one end and a BNC connector on the other. There wasn't anything in the instructions about this and I wouldn't have given them another thought as we just use the existing wire and add our own BNC connector. However, one of the coax wires on this job had been cut leaving the 16/2 wire the only thing intact. On a whim, I hooked those little adapters up to the 16/2 at either end and it just worked. So that is a 4K camera sending its signal 155 feet over a speaker wire and looks just as good as being hooked up with a network wire. I am completely shocked by these and we will be ordering more.

works great.. added a splitter at transmitter end was able to run two cameras on one rg coax cable

I am using these EOC adapters to connect a low-power WiFi AP and a HomeKit gate controller at the end of 1800 ft. of RG11 coax that runs from the house to the gate. I have a PoE switch, but I went ahead and purchased the Linovision 30W PoE injector in order to get the most power down the cable. You'll need to be able to add BNC connectors onto your coax, which can be a challenge. Once it's all hooked up, though, network function works, PoE works...so, for basic network connectivity, this is a great solution. There is a caveat. These modules only pass unicast IP traffic. I deducted a star because that information should be included somewhere in the description or specifications. HomeKit, and most other smart home systems, rely upon Bonjour/Zeroconf, which relies on multicast traffic--primarily mDNS--for service discovery and general operation. So if you want to use these to extend your network out to a smart home device, including smart cameras, you'll need to have a way to publish the device's mDNS record(s) manually so your smart home controller can find it. For example, you can use dns-sd on macOS, or avahi on linux...but it's non-trivial. Don't expect it to "just work." Linovision's tech support was responsive to my question regarding this issue. It took them a few days, but they did finally confirm that this device does not pass multicast traffic. This makes a certain amount of sense from the standpoint of optimizing network bandwidth, but it should be mentioned in the documentation. It would be really nice to have the ability to enable multicast if desired. All in all, the fact that I can get solid PoE and network connectivity—lack of multicast notwithstanding—over 1800 ft of coax is amazing. These units are super compact, they don’t seem to run hot, and by golly they work. I’m impressed. Update: After running great nonstop for several weeks, the "Receiver" (which is the module that "receives" ethernet & power and sends it down the coax) completely died. Linovision tech support came through immediately, and had a replacement to me very quickly. So, another customer service win for them. I am, though, concerned about the root cause of the failure, because I don't want the new one to die in a few weeks. Since the unit has an internal heat sink, and it's associated with the power circuitry, I'm going to start with an assumption that something overheated in or around those components. I'll see what I can do to keep the replacement cooler, and see how long it lasts. Fingers crossed. Update 2: The replacement unit has been in service for over a year now, and is working great. Apparently my gate is a high-static area and tends to eat electronics during lightning storms. After adding good grounding to the coax, the DC lines, even the gate itself, things have become much more stable and reliable.

Worked beautifully. Save the cost of expensive rewire.

These things got me out of a jam. Installed new cameras and they were all bnc cams, ran new lines for more bnc cams but when the next cams arrived they were poe, renting another lift and rewiring lines was out of the question, these poe over coax converters saved the day, install is super easy plug and play, video quality is awesome 4K, speed and connectivity is solid no dropped or freeze frames, definitely worth the price, if you need support they have youtube videos for you to follow but it's pretty straight forward, probably won't need it, instructions are printed right on the box.

Solid performance from this set. Used to power a new 4MP IP camera over an older siamese RG59/16-2 cable (approximately 80' run) that could not be replaced without major demolition. Plugged directly into the NVR port supporting POE+ Our client saw no difference in the performance of the camera using this EOC balun set as compared to the other cameras operating on Cat6E. Make sure you have room on the camera end for the transmitter, moderate sized j-box or within the building structure itself.

The project worked great for one day and then just stop working. to unpredictable to be used this for this application. It was used with an old coax cable.
