Hello, forum! I encountered a problem when using PoE extenders from EnableIT and decided to ask your opinion. I have several CCTV cameras in the office, and I decided to connect them via PoE extenders at distances of about 70-80 meters. So far everything seems to be working fine, but sometimes, especially in rainy weather, the cameras start to freeze, or the video loses quality. The question is, could this be related to the extenders, or rather to the cable? I use Cat5e, could this be the reason? I would like to understand what could cause such surges, and how to make the system more stable. Has anyone had a similar experience?

Interesting discussion! I have also encountered using PoE extenders from EnableIT, and in my experience, most of these problems are indeed related to the quality of the cable or its improper installation. Of course, weather conditions can have an effect, but first of all, you should pay attention to the cable itself and the type of connections. As for power supplies, I also agree that it is important to consider the load on the system, especially if you use many devices. I had a situation when, when connecting several cameras at a distance of about 80 meters with a regular Cat5e, delays began to appear, and I also decided to replace the cable with Cat6 - the result was better.
I have just recently Compare PoE Extenders from EnableIT, so I can share my experience. First of all, it should be immediately clarified that PoE extenders in principle can be prone to certain problems if you do not take into account several factors. As for the fact that your cameras sometimes freeze - there can be several reasons, and the cable is one of the most important factors. If you use standard Cat5e, signal losses can occur at distances of 70-80 meters, especially if the cable does not meet the recommended specifications or there is some damage along its section. Even small defects in the wiring or a bad connection can cause such surges. If your cameras require high bandwidth, then Cat5e may not be ideal. I would advise trying Cat6 or Cat6a - they cope better with data transmission over long distances and ensure stable operation at long distances. Even if you use good cables, it is important that the connections are made correctly: if the cable was poorly connected somewhere during the installation or its conductors were damaged, this can also cause problems with the signal.
