dudu_georgescu 0 Posted March 23, 2009 Hi, I am using the a pair of the following balun: Muxlab 50032 (http://www.muxlab.com/assets/files/datasheets/VE_Quad_Video_Balun.pdf) to run 4 video signals through the same cat 5e cable (Belden cable). Unfortunately I am getting some signal interference (i.e. waves on the screen of the four cameras) significant enough to trigger the motion detection of the DVR each couple of seconds. If I disconnect any three cameras, then the remaining one works properly, no interference. My questions would be: (i) is this interference normal (because if that is the case, I would have no choice but run more cables and I hate drilling holes in-between floors) (ii) could it be a problem with the cable (good quality, Belden fast-cat 5e, rated for 350MHZ, works with no problem if I only use it for one camera) (iii) could it be a faulty balun (No shielding in between signals) (iv) could it be some static, and if I discharge it somehow, then everything would work fine (iv) some other thing Any kind of help would be greatly appreciated.
