Hi, I hope someone can help me out. I have bought a 8 camera cctv DVR system from ebay (http://www.ebay.co.uk/itm/900TVL-8-Channel-1TB-CCTV-DVR-Outdoor-Camera-HDMI-Home-Video-Surveillance-System-/141392956671?pt=UK_CCTV&var=&hash=item20ebad4cff) It is running with a total of 8 cameras, 7 of them are running from 18 meter pre-made cables and 1 with a set of balun's (http://www.kenable.co.uk/product_info.php?cPath=212_305&products_id=6986) with about 10 meters of cat6 I have checked all the cables, wiring and cameras but the camera on the balun gives me a very bad picture, but only at night, in the day time it is fine. Any advice on this would be great!

Hi, Thanks for the advice, The power supply is a shared 12V 4A for 4 cameras, I would of though this would have been enough, I also have another camera right next to this one, pointing to the right, it is on a pre-made cable and does not give any trouble at all. I am only using a single twisted pair for power brown 12V + and brown/white 12V -, could that be giving me voltage/current drop and causing this trouble when the IR kicks in? as I didn't even think about it, I will try to use brown & brown/white for 12v + and blue & blue/white for 12v - and post my outcome. Thanks
