I'm finally finding some time to dedicate to home security & automation again and my first target is an issue I've been experiencing on my cameras. I'm encountering quite a bit of "noise" on many of the feeds, which are horizontal lines and create a wavy look for the picture. It's driving me nuts and I'm not sure exactly where to address the issue.
My first assumption was that I was experiencing an issue with some reused cable from some older cameras, which I had to splice and rewire to get to work. I purchased new cable and hooked up my first camera and while it appears slightly better, I still see lines. Then I recalled I consolodated some of my 12V wall warts into an Elk power distribution unit - (PD9DC12- Link to Example) a while back.
I found that the lines went away for the most part when I went back to using a wall-wart directly. As it stands, I am only using 4 cameras currently on the distribution, so it's not really overloaded. Any ideas on a power distribution solution for 10+ cameras that wouldn't degrade the picture. Would a computer power supply deliver the correct power to the cameras on the 12V feeds?
I realize this has been discussed a bit in other topics, however I believe it mainly revolved around Skibum's massive power supply. Thanks in advance for any ideas. Although I'm currently playing around with the feeds and they may be up and down, you can see examples at my website's main page. The cameras are on the right hand side.
