A big THANK YOU Kawboy! " title="Applause" /> " title="Applause" /> " title="Applause" /> You were spot on! The four affected cameras were all running off the same PSU. I swapped this out for another which I had and BINGO all the interference has gone. You've saved me a lot of time and effort (and probably money) and I'm really grateful for you taking the time to suggest this. I hope this thread can help others with similar issues... Doug

Thanks so much - I'll take a look - yes, four cameras went at once, about 3 years after installation and they are sharing a 12v PSU. I'll take a look and very much appreciate the pointer! Doug

please help if you can, this is driving me nuts!!!

Greetings everyone, great forum and thanks for allowing me to post a question. I have a K-Guard 8 channel DVR system, with 8 standard wired cameras protecting my property. I installed this myself using the supplied/standard equipment. That was back in 2010. Since then it has work flawlessly and I've been very pleased with it. However, about 4 or 5 weeks ago, I started getting interference on 4 of the cameras, which I had not had before. This takes the form of slow rolling horizontal "faded" lines, usually 2 on screen at any one time. The affected cameras are all on the same side of the house. Would anyone have any idea what might suddenly have started affecting them? The next door property is about 10 feet from my house. Thanks for any help you can offer, happy to answer any further questions. Doug.
