yes your right "ring" is the wrong word ( maybe "rail" would have been better ) and I have not made my mind up at all.. just not keen on drilling lots of holes in walls to get power outside. My thought was have 1 cable running 12v @ 10A from 1 psu , and as each camera need a waterprof junction box I could stick a 2A fuse in each box for each camera If 1 camera goes down the rest are fine, You say im gona have problems from day 1 could you please help / enlighten me here

So if I run a ring of 12v @10A ( 5 cameras at 2a ) each splitter then goes into juuction box with a 2A fuse to the camera all should be good ? why never a low voltage ring?

so your saying im to use 12v 2A psu to run all 5 cameras? NVR and cameras are the same make same make

OK be gentle with me, I'm thinking of getting a wireless / wifi system with 5 camera's , each camera has its own psu 12v 2A instead of drilling 5 holes to get power out I was thinking of running 1 cable of 12v and 10A around the house and at each camera an ip65 box for the juction would this work ? would you go slightly higher than 10A ? and what sort of cable to do the ring ? hope this makes sense Just trying to work out how im gona get power to all the camera before purchase , cheers John
