    Just found the shop is having 2 phase on the electricity, I have checked the earth, everything seems to be fine, Even the looping is fine, I have no idea what to do?

    It is a restaurant. I think he is running in Single phase I have to check this!. I will try to ground the case as you said and give the results. What type of ground loop devices do you suggest? Here my work is to install only the CCTV. If the real problem is with ground looping, or electrical wiring then I have to speak to the owners of the shop. Thank you for the advice

    As you mensioned I have changed the camera & I have done a new cabling to those effected cameras. I do not see any changes. After I saw the plasma screen. I did tell the guys to not to use it. So far they do not use it. Since this issue is a high priority. The shop is running 24/7. Well I saw slight disturbance even before the plasma TV in those cameras.

    Well, all the camera's power supply is comming from one power source. As far as I know the shop is fully functioning and after our cabling no other work is been carried out, and I do not see any. Just a 42" plasma screen is been fitted. Even that is not on our line of area. All our cables are running inside a plastic casing, Now the shop is fully fitted with plaster celing. so it is very difficult to see any power is crossing our cables inside/Middle of the covered area.

    Hi there, I have installed 7 Cameras in a shop. Out of 7 3 of the cameras are getting lines across the picture not heavy. There a few meters apart. They were working when I installed them. After a month or so I get this problem. Any help would be greatly appreciated. Thank you
