Weather protection for ethernet cables?
« on: February 24, 2021, 11:57:02 AM »

One of my CCTV NVR cameras as always had a problem after it as been raining. It doesn't happen during the rain but after. The only thing I can put it down to is that camera ethernet cable is laid on the roof of the extension (the other 2 are going along walls). So I'm thinking that the water over time is somehow getting in to the cable as its laying there.

The problem is with that particular cable it goes through parts of the house I can't reach (in to the loft) etc. But I think the main problem is outside on the roof. I know there are weather proof ethernet cables. This could be one as it came with the SWANN camera. But I can't really replace the whole cable because of where it is.

So my question is, does anyone recommend something I can manually wrap around the outside of the cable (the part outside the house) that will help protect it against the water as its laid there?

Amazon market some ethernet cables as ‘outdoor’, such as the 50m one I have just bought. I’m intending to put my network cable inside nylon-ribbed semi-flexible pipe though, to keep all water out, as well as protecting against mechanical intrusion.

  Hose pipe, sealed at both ends to keep the water out. As I have said elsewhere, I have had coax cables going to various aerials and and a satellite dish out in the garden, with everything working as installed after many years in the ground. PVC cables do allow water to get in, if left in water. Under ground cables are often filled with grease and metal barrier fitted to prevent this.

  What I am puzzled about is the fact water getting into the cable does not cause a continuous fault to your camera. Years ago I wanted  to quickly get my 12 volt battery supply extended to my new shed. I saw a lump of mains orange extension cable  laying around, so I dug a long groove in my lawn and placed the cable carrying 12V  into the ground and buried it. A few years later the -ve earth wire disappeared. I temporarily made the supply good by connecting the -ve to the mains supply earth. Ultimately I dug up my old 12V cable feed and found that the -ve wire had corroded away. I replaced the 12V feed by putting  a new cable into hose pipe, and that has lasted for years. Hope no electricians are looking at this reply................

Thanks for the suggestions guys.

It is very weird. I only get problems with the camera after it has rained (during it still tends to work). The picture will keep cutting out, so the time will keep jumping as it jumps frames, and then it'll freeze the picture on that camera and when I reset the cameras it won't show, the other 2 will act normal through-out all this.

I think at some point I need to setup a new camera system. It would be good to be able to use a wifi setup instead of ethernet cables. But powering the cameras will be the issue. I wonder if there is a small solar powered panel that could attach to the cameras that would supply it with enough power?
