simyf 0 Posted February 6, 2009 I'm using 5A 12VDC switching power supply for CCTV cameras and noticed that the Video had interference. Anyway to eliminate this? I have tested using 12V DC Transformer type of Adaptor to the camera and the video quality is normal. Share this post Link to post Share on other sites
