I have also used PoE extenders from EnableIT and they really made my job a lot easier. I had a situation where I needed to extend power and signal over quite a long distance and standard solutions were not enough. I agree with the previous comment that it is important to monitor the quality of the cables because it can really affect the stability of the connection. And one more thing – PoE extenders are ideal for working with devices that require stable power, such as CCTV cameras. For example, we have such a system on site and using these extenders we were able to significantly improve the network configuration.
