hazim 0 Posted April 18, 2013 Dear all. I've installed two analog cameras in a warehouse about 70m long. The cameras worked well for several days, and few days ago in a rainy day both cameras stopped working. I found the problem was that the 75 Ohm resistor at the video signal output (smd resistor on camera PCB) was fused in both cameras. This could happen due to a lightning but no lightning happened that day. The coaxial cables of the cameras are placed on the top of the warehouse, and the cameras are installed on the iron of the warehouse, so I'm thinking if any charges for the "stormy" atmosphere was the reason. I've checked the cables and they are ok. Any ideas? Hazim, Regards. Share this post Link to post Share on other sites
bigglebowski 0 Posted April 22, 2013 What do you mean by the resistor was fused? Ive heard of fusible resistors before and they are used for protection in a circuit and when they fail you would call it "open". So if its fused that seems to imply that it is working correctly. So I am conFUSED (get it) boo Share this post Link to post Share on other sites
hazim 0 Posted April 23, 2013 Yes I mean that the 75 Ohm resistor became open. Share this post Link to post Share on other sites
