Afraid not, you're working with a complete novice here who literally bought a system off Amazon and plugged it all together and got away with it for 2 years...lol Quote Link to comment Share on other sites More sharing options...
PeterJames Posted November 6, 2016 Share Posted November 6, 2016 You need to check that the power supplies are working. If the new camera was faulty or you accidentally shorted the cable, this could have blown all three supplies. With a multi meter you will be able to tell what voltage if any is coming from the supplies. You lose current through cable, you should cut the cable to length rather than having excess coiled up.

the_italian Posted November 6, 2016 Author Share Posted November 6, 2016 Great, thanks. So in theory, if I just buy a new power supply, what should I be buying to safely run all 8 cameras? And should this solve the issue rather than worrying about the other power units? Is there any way for all 8 cameras to have been damaged or the DVR itself? Or is it more likely to be purely the power supply issue? Quote Link to comment Share on other sites More sharing options...
PeterJames Posted November 6, 2016 Share Posted November 6, 2016 I would normally allow 1amp per camera, so a 2amp psu will run 2 cameras. But first you need to check if the existing PSU's are working because if theyre not you need to find out what caused them to stop working. Before you fit any new ones Quote Link to comment Share on other sites More sharing options...
the_italian Posted November 6, 2016 Author Share Posted November 6, 2016 No bother. Based on my limited ability and understanding of all things electronic, would you suggest getting someone in to have a look at it then? I can buy a multi meter but the reality is I'm not really going to have a clue what caused them to fail, if that is the case. Quote Link to comment Share on other sites More sharing options...

Probably best, an engineer should find your problem quite quickly Quote Link to comment Share on other sites More sharing options...
