paul44 Posted November 14, 2014 Share Posted November 14, 2014 Hi all, I have a site that has 8 analogue cameras. They are connected by cat 5e using all in one video and power baluns, Ive had 3 problems with cameras just dropping out. Each time it has been a case of replacing the balun. The only reason I can think of is that 2 months ago one of the external waterproof boxes leaked and buggered the balun up. i replaced it and shortly after the psu died, possibly due to the balun outside shorting power out out. All the ones that have failed since are internal, and are secure in enclosures. Anyone had a problem like this before? Any ideas? Quote Link to comment Share on other sites More sharing options...
SouthernBrad Posted November 15, 2014 Share Posted November 15, 2014 What Baluns are they? You mentioned a PSU are they active baluns each end? Quote Link to comment Share on other sites More sharing options...
Steven_W Posted November 22, 2014 Share Posted November 22, 2014 I went to a job that had been done by someone else who had used external cameras with a high power draw when the IRs were on. The cables were all run in during a refurbishment. I thought the cameras were burnt out at first, but once I cut the cable back & reterminated with new baluns they were OK again. Only thing I noticed was that the installer had used copper clad aluminium CAT5 (CCA) which is never a good idea and I don't think the cable was man enough to handle the power draw. I reckon I'll be recabling that one at some point! Quote Link to comment Share on other sites More sharing options...
