mudcow007 0 Posted February 6, 2018 Hello all, i have just installed a DS-7204HUHI-K1 with x3 DS-2CE56H1T-ITM cameras. I'm using Cat5 with baluns (cheap ones from eBay). Stupidly, i have one run of cable for 2 of the cameras (one pair video, one pair power on each), an on the single camera, one pair video with another pair power with the rest of the unused pairs "nipped" off. Cable runs are short, say 20 - 30ft Max Looking at the video output from a monitor connected to the NVR/ DVR the image is grainy an slightly pixelated (spelling?) could using baluns cause this? Should I be using coax & bncs? maybe im expecting too much? Share this post Link to post Share on other sites
jeromephone 6 Posted February 6, 2018 I would check the power at the camera and try running a short bnc patch cord and power wires to the camera and see what kind of picture you are getting running power through size 24 wire(cat5) vs 18 gauge stranded copper is bound to cause more voltage drop than the 18ga which is a common power wire size. also if running CCA the voltage drop could be worse/ if you have followed this forum you will note that CCA is never reccommended and may be against code in some areas Share this post Link to post Share on other sites
tomcctv 190 Posted February 6, 2018 +1 Plus when you say bought from eBay baluns do they look like this eBay is full of these and they are not baluns. Share this post Link to post Share on other sites
