bentech 1 Posted October 17, 2016 Hi , We have a few cams that are mounted to a big metallic frame (Outside gate) for 5 years now. Every 1 or 2 years , we got damaged cams because , i think , lighting. Opening the cams , we can see burned components inside. We use 12 VDC as power and baluns for video transmission. I don't know if damage is coming from power ( i doubt) or from the BNC . How can I protect the cams from this ? Tks for your help.... Share this post Link to post Share on other sites
