NOYAFA NF-488 POE Tester for Power Over Ethernet, Network Cable Continuity Checking , Switch Loop-Back POE Detector

NOYAFA NF-488 works exactly as described. You can't ask for more than that. At this price point I was prepared to be disappointed because others cost so much more. But I was pleasantly surprised. It does what it says it will do which should not cost all that much since it ain't much. But others do charge a lot more to do the same thing. It does feel very light and thin plastic so don't drop kick it across your room and you should be fine.

I am very happy I picked this tool up. I run alot of ethernet cable of alot of different projects, one being POE cameras and needed to test the POE output and this was able to do that at a great price point compared to alot of other testers out there. Has lots of functions to only need one tester to carry around. Came in a nice carrying case to protect it and increase it's longevity on the job. Found it easy to simple to use.

J’ai peut-être sauvé mes deux caméra poe, des deux d’injecteurs poe dit standard qui ne l’était pas.

Good POE/ethernet tester. Used it to figure out the POE version coming out of an adapter. Also used it to figure out which twisted pairs were incorrectly lined up. Worked great.

This POE checker paid for itself in its first use. It worked as described, and the instructions were good enough to ensure I was using it correctly. I have a bunch of externally installed POE cameras (monitored by Blue Iris). Every once in a while one goes out and I need to determine the source of the problem. Usually it's a camera, but sometimes, especially for cameras 150 feet away mounted on the stairs down to my dock, it could be a switch or cable problem. Or in one case for me, a bad connection in a barrel connector (for connecting two cables together). I had to analyze the worst case today and this meter saved me multiple trips down to the dock. Using its continuity tester I was able to determine that cable segments were still good. Using the POE tester I was able to determine power was getting to the dock, and it was 47+ volts, still good enough to power a POE cam. That left the camera, which had gone out. Without this tester I wouldn't have known that my segmented cabling was not involved in the failure. This tester will be put to use again, I'm sure. POE cams and outdoor cable runs have their failures.
