Mike J Posted December 17, 2007 Posted December 17, 2007 Hi Guys I think I may have answered my own question on this but I thought it was worth running past you. Just did a job this weekend where I had to install 3 cameras into a garage on a domestic property. The client had an external Cat5 laid to the house so I figured that using Balluns was a great solution. I got my cameras from Gtec Security (www.gtecsecurity.co.uk) and I asked if they had passive Balluns. They did at

Mike J Posted December 17, 2007 Author Posted December 17, 2007 Thats the kinda thinking I like!!! Will do that. Not a power problem as the cameras are powered locally and work on a test monitor.

arfur mo Posted December 17, 2007 Posted December 17, 2007 not sure how much you know about CAT5e, but it has connection convention for colour code use. cheap LED testers offer very basic tests, a reasonable tester looks at cable mapping and split pairs, as with all test kit the better it is the more it costs. The colour code should be as follows and IS important to adhere to _: 1 White/Orange 2 Orange 3 White/Green 4 BLUE 5 White/Blue 6 GREEN 7 White/Brown 8 BROWN if the above is correct make sure the cables are full pressed down into the IDC connectors, if you don't have a punch down tool use the back of a stanley knife blade (with obviously greatest care taken for your own safety ) regs alan If you think education is difficult, try being stupid!!!!
camerabloke Posted December 17, 2007 Posted December 17, 2007 if they work on test monitor it has got to be baluns or cable,try checking continuity if the balun trick doesnt work,or the dvr input might be faulty try swapping them artound Eucam Security Systems 0845 4630 746 www.eucam.co.uk

Neutech Posted December 18, 2007 Posted December 18, 2007 Not being cheeky but what way did you wire it all into a JB? Have you tried putting signal from each balun down a pair? Green/White cam 1 etc other thing is 414v 4 port Balun, rj45 into hub then Co-ax to each cam Have used a number of them with no problem as for the
breff Posted December 18, 2007 Posted December 18, 2007 Make sure each camera is using a single twisted pair, you may have one using a pair and the other 2 crossed. The opinions I express are mine and are usually correct! (Except when I'm wrong)(which I'm not)
