Hi everyone,
I know there are a million different post on this topic out there and people usually have all kinds of different problems running ethernet cabling but I just ran into a (at least to me) very interesting problem which I can’t explain to myself and I couldn't find any reasonable explanation for so far. That’s why I thought I put this out there to the community and maybe somebody with more experience and brainpower than me can offer an explanation.
Recently I put up a camera network with 10 IP cameras and on 3 different buildings, using a Ubiquity PTMP setup and TP-Link POE Switches as well as good quality cable (Ubiquity shielded outdoor cable + Shielded connectors).
After some tweaking the system is running great and I have no dramas but one.
The one problem I am having is one camera about 40m away from one switch which I can’t connect to (not the longest cable I ran).
I tried various different things to get it to work:
- I made sure the cable is running under the roof avoiding any electrical installation.
- making sure Camera is getting Power -PoE is delivered all the way and the camera is booting and operational, according to the LEDs flashing (tested with a POE tester as well as a different camera,
same camera tested closer to the switch as well where its working fine).
- I even tried a different switch and rerouted a whole new cable to tick boxes.
- I redone all the connectors multiple times (making sure my technic is right) and tested the cable with a cable tester
- still no results.
That’s why I figured out the signal must be the problem and cut the cable in the middle and put a switch in to '''repeat'' the signal and it works?! -_-
Atm I just can’t explain myself why POE is delivered fine and just the signal seems to cut out along the way for some reason (on this short distance).
I really hope somebody can offer a solution because I really don’t want to set another power point and waste a switch for one cable.
Thanks very much
Phil
