NVR IP camera's will not work on one side of my house. Cannot find cause

I have a 16 channel NVR system. 13 camera's work fine, but any camera's I mount on one side of my house stop working. no error just black display. I have tried swapping camera's and channels and the camera's will work once I move them, but not on that side of the house. I tested using shielded Cat7e cables and that did not help. there are no powerlines or electrical equipment on that side of the house. There is nothing in my crawlspace, attic space no anything near the area. The only thing is a gas line for the fireplace. it runs the entire length of the wall and the camera's would always be 5' from it. Xcel says there are no signals in this line.

I have been troubleshooting this for 6 months. I can take a camera and cable and channel fully working on another side of my house and the moment I move it to that side of the house. BLACK signal. No error. I have put emi/rfi filters over the cables. i have run the cable UNDER the house, over the attic. longest way around. Nothing works.

the camera's get IP addresses and from all setup screens look just like all the other channels. manufacturer cannot find anything wrong with any of the equipment.

Note: I had ZERO issues on this side of the house when I had the same brand DVR system. I just switched to a 4K NVR and this started immediately

Are you actually moving the cable? Did you makes these cables yourself? If so did you use the 568B standard?
 
With ^^ @fenderman.

So you are 100% sure all these camera's work with a 1m prefab UTP cable?

And if you pull that 200m cable to the working side, and pull that same cable to the other side, that same cable fails to work?

If that is the case, I bet 2$ that you have an alien power plant in your proximity which interferes with all possible ethernet communications. ;-)

Happy Camming :p

the system came with 16 100ft cables. I have tested replacing the 3 cables on that side of the house with shielded cat7e and it didnt change anything. If I Hook the 3 camera's up with short cables up next to the NVR, they all work fine

If I take a working camera from the opposite side of the housewithout even disconnecting the cable, the camera display goes off as soon as i get it to that side of the house

It’s important to answer the questions asked. When you made your own cable did you use the 568B standard.

Hang on, you plugin your camera as side "left", you walk, with the cable plugged in, and when you arrive to side "right", that working camera is dead?

Sorry, I increase my bet to $10 on that alien signal disruptor :-)

yes. something appears to interfere on that side of the house, but 220, cable, HVAC etc are on the other side of the house. The sole item on this side is the Natural Gas line. Xcel energy says my meter is not RF . I have been suspecting it is an RF meter, but how would it stop 3 wired camera's...

connect your laptop/pc to one of the poe ports and set to dynamic ip. you should then be able to access the poe cameras, obviously 7 of the remaining cameras.

Not sure if the nvr user interface has a detect function.
 
So you are not moving the physical cable as sort of suggested but simply moving a camera? If this is the case then it would suggest a cable problem?

If you are moving the physical cable then how are you able to do that and if you are the what happens if that same cable is plugged into the NVR and with it cooled at your feet you plug the cam in?

it works fine on the same 100ft cable in the house.

After looking up my gas meter by image, I am positive mine is an FR meter (Automatic meter reading (AMR)). Xcel Energy drives trucks around that pick up the RF signal.

Anyway, today I went to lowes and got 25 feet of aluminum mesh 48" wide screen and I built a 5 sided Faraday box around my meter leaving the street side open for the city to get signal. It was a $30 project which is way less than the cat7e cables were

Low and behold the camera's came on. they are slightly glitchy, but have signal. I am guessing the meter is the culprit because this has been 6 months and i have signal for the first time on that side of the house. I will keep working the faraday concept

Welcome to IPCT ! :wave:
Thanks for sharing with us the (apparent) solution...you made what is generally a boring intro by a newb VERY interesting and educational!

My guess is that the RF isn't getting into the cables; it's getting into the cameras. I'm curious: do the cameras have metal bodies or plastic bodies? If the bodies are plastic, then lack of shielding could be making the camera electronics vulnerable to RF interference.

You could test this by shielding one of the cameras, and seeing if that clears up the remaining glitches. Or, if you have another model of camera with a metal body, you could install it and see how it performs.
 
But your definitely on to something! You had results with the faraday cage. Maybe try different type of screening material. Try one that is steel, maybe with a 1/4” mesh

they are metal framed. i tried wrapping a camera in 8 layers of foil, but it did not do anything
