landroverjack 0 Posted March 9, 2015 Hi all I bought a cctv system from domar solutions before Christmas got around to setting it up this weekend. but im having problems with the cameras. Its a 4 camera system but only two are working. i have bought both cameras that arnt working inside and tested them on a 10m roll that i had spare and they both work on that. in my mind there is something wrong with the cabling. I then tried one of the cameras that was working on all four different cables and it works fine on all four. so im lost to whether its the cameras or cabling. the thing that is odd the cameras that dont work, when plugged in there is a high pitch buzzing. the dvr is a H.264 dvr and the cameras are Zxtech Dark Eagle King 60IR Outdoor Bullet Camera 700 TVL CCD 60M Night Vision 2.8mm-12mm Lens cheers jack Share this post Link to post Share on other sites
