Review on Cudy Gigabit PoE Extender - 10/100/1000Mbps, 1-Channel PoE Repeater & Amplifier - Wall-Mount, IEEE 802.3at / 802.3af Compliant, Plug & Play (Not Compatible with Passive PoE) by Cedric Edwards

We wanted to install a security camera outside our house (we have a few more in different locations). However, we are in a large rural area and the road is approximately 450 feet from the house. We tried solar/wifi cameras and even with external hotspots the wifi connection was unstable. One day I noticed a telephone box on a pole that we were trying to install and when I opened it I found 4 pairs of unused CAT3 wires - 4 pairs consists of an Ethernet cable (although it's usually CAT5 or 6). This cable went straight to my house through a cable duct. I continued with the network connection to my PoE+ switch. It worked at first, I was amazed, Ethernet ran over 500ft - max spec is around 330ft. However, it proved unreliable and PoE was not reliable either. No wonder my cable tester measured the length of the entire route to be just under 600 feet (roughly 600 feet) — nearly double the spec. up to 3 extensions for a maximum length of 1320 feet). I decided to try a POE10 first as it was supposed to be in the demarcation box in my house. I replaced the connection with two RJ45 connectors and plugged in a POE10, BOOM! It worked right away, my PoE cable tester showed full voltage at the end of the 600ft line - in fact the Cudy POE10 drives 100Mbps Ethernet over a 550ft CAT3 cable - AMAZING! Best of all, no electricity is required, the power strip is powered by the extended PoE+! Our PoE+ pan/tilt/zoom camera, which consumes around 15-20W PoE+, works great and produces great images. My managed switch tells me I have a 1Gbps connection, but I can't confirm that as it sees the Cudy injector and the camera itself only needs 100Mbps. One day I will test a more network intensive device but for now the Cudy POE10 injector works great and solved a big network problem for us. We could even fit one of the 2 port weatherproof Cudys at the end of the line and try to add a second chamber. Kudos to this device, can't recommend it highly enough! Five stars all the way! Disclaimer: What I've done is totally non-standard, and I'm not saying everyone should try things like this, but if it works in very complex environments like this, there shouldn't be any problems in more typical use cases.
