UltraHighResolution Posted May 3, 2007 Share Posted May 3, 2007 Has anyone used the Network over mains modules to transmit IP cameras? I have found one from Devolo which claims 200Mbps at distances of 200 metres. Does this mean to go 400 metres I could go Camera -> Network to Mains adaptor -> 200m Mains -> Mains to Network adaptor -> switcher -> Network to Mains adaptor -> 200m Mains -> Mains to Network adaptor -> recorder ??? for any help Link to comment https://www.thesecurityinstaller.co.uk/community/topic/18881-network-over-mains/ Share on other sites More sharing options...

But are there any sites out there with these sized premises that don't have single phase? Never dealt with mains networking but I would have thought it's dependent on single phase. I could be wrong though but it does seem to add up what I mention.

UltraHighResolution Posted May 3, 2007 Author Share Posted May 3, 2007 Hi The application is specifically a stately home with mains lighting all over the garden and mains running the electric gates at the end of the drive some 400 metres away, I am not an electrician, is there a way to check the phase/ continuity?

You need to look at the mains. Stately home suggests large so every possibility its 3 phase. As i understand it, Network over mains must be on same phase and no ELCB and RCDs either.

Just a suggestion UHR, but maybe have a look at the model plate / wiring on the gate drive motor; it would hopefully indicate whether it's a single phase motor ... or not.

whistle Posted May 3, 2007 Share Posted May 3, 2007 I tried to do cat5 transmission over 3 pahse and it DOES NOT WORK it must be on the same phase. Agreed, we had loads of problems on a site with 3 phase and cat 5.

Not necessarily proof. Motor could be single phase...but on a different phase to say the PC/Router.

leesutton Posted May 6, 2007 Share Posted May 6, 2007 The 2 modules have to be on the same phase or they cant talk to each other. lee Lee Sutton E-Mail: leesutton@centurianfire.co.uk Website: www.centurianfire.co.uk Phone: 0845 094 9870 CENTURIAN FIRE & SECURITY (part of centurian group limited) Link to comment https://www.thesecurityinstaller.co.uk/community/topic/18881-network-over-mains/#findComment-164967 Share on other sites More sharing options...
Gopher Posted May 7, 2007 Share Posted May 7, 2007 Yeah I've read reviews of items similar to what your looking at and they clearly tell you that you cannot fit anything in the way of them they both have to be plugged into sockets and be on the same phase - no Surge protectors, it's even recommended you don't plug it into a 4-way extension either. Also they way your planning it would WORK but only and I say ONLY if the 2 sockets either side of the switcher were on different phases as other wise you'd get interferance as each unit tried to transmitted on very similar frequencies.
