Hi Everybody!.. I am new to the forum and would like to ask a question which might in some way help someone else with this problem. I am an alarm engineer and have only done the odd cctv install with honeywell domes and dvr's and all has been well. I have installed in my home an ademco 4ch 1TB dvr with a Samsung 3080P and Samsung monitor with hdmi connection. To be honest the quality is superb!... My problem is I have installed an RG59 from the attic where the equipment is down to my Sony smart tv in the living room. I have used the Spot Monitor from the dvr which is BNC then used an RCA to go into the tv ( Video ). I am getting a great picture for around 6 seconds then it just goes blank!! I then put it into the scart on AV1 and still the same...great picture but for only 6 seconds....It is not the cable as I have now run a brand new cable and still the same... also if the connections were dodgy I would get a terrible picture or all snowy. Question is can you have a BNC at one end and an RCA at the other?. Or does any of you tech guys have a solution for spot monitor. Many thanks in advance to all!. Regards. Rob
