macky872 Posted September 10, 2013 Share Posted September 10, 2013 I have installed 4 cameras ,longest run 100 metres , But the pictures are poor is this due to me using only two of the wires for + and two for - , the cat 5 cable is solid copper , I have used this before to longer runs , with 4 for + and 4 for - , and it worked fine, is there a limit o the distance per how many wires you use. Any help would be appreciated. Link to comment Share on other sites More sharing options...
Alarm Protection Posted September 10, 2013 Share Posted September 10, 2013 I would never use cat5 to power cameras. Rip the cabling back out and install proper cable for the best results. ! Link to comment Share on other sites More sharing options...
PSE Posted September 10, 2013 Share Posted September 10, 2013 Going off the above post, I'm hoping you have used baluns for it, not just connected the ends to the video signal and hoped for the best ?  Sounds daft, But had to ask...  Explain exactly how you have connected them up then we can go from there Link to comment Share on other sites More sharing options...

macky872 Posted September 10, 2013 Author Share Posted September 10, 2013 Yes the connection is baluns with a seperate PSU for power running 4 cameras at 1 amp each all on a seperate cable not using the cat 5 for anything other than picture.

Ronnie Posted September 10, 2013 Share Posted September 10, 2013 Eh? Cat5 is perfectly suitable for powering cameras. Link to comment Share on other sites More sharing options...
macky872 Posted September 10, 2013 Author Share Posted September 10, 2013 I have not been very clear , here goes The cameras are powered by separate cable ( not cat 5) and PSU. The cat 5 cable has 8 wires which I have used on 2 cameras, 2 to + 2 to- and same for the second camera. Should I have used 1 cable using 4 per camera ?

whistle Posted September 10, 2013 Share Posted September 10, 2013 We have done this for well over 200m on cat 5 with baluns. Infact I am powering up a Pelco dome tomorrow that's on cat 5 and that's 300m from an axis Q7401 encoder. Link to comment Share on other sites More sharing options...
macky872 Posted September 10, 2013 Author Share Posted September 10, 2013 How many of the wires would you connect to the balun , I have used 2 per terminal over 100 meters. And should I have done this differently. Link to comment Share on other sites More sharing options...
