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

try the baluns that work on the 2 cam cables that dont, if they dont work its gota be something else.

power?

shorts on cable?

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.

The client had an external Cat5 laid to the house

check the cable.

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 )

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

how rude

how rude

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

Make sure each camera is using a single twisted pair, you may have one using a pair and the other 2 crossed.
