ive got a 4 way avtech, with 4 cams, was working ok untill i added a fourth camera, now 2 of the cameras have got coloured lines going through them, when i diconnect all the cameras they are ok when only one is connected any ideas

bosch dome cameras, 2.5 amp 24v psu the problem started when i added 1 camera used cat 5 for power , i will swap this out for flex and see what happens.

samsung have got a good range of kit out for this , not to expensive to

no 2 power supplies but even if i attach 2 that are of 1 psu i get 1 good picture and 1 with coloured lines on it ?
