sparky83 Posted July 18, 2005 Share Posted July 18, 2005 Ive seen T connectors advertised before in CCTV magazines but never seen them used. We always loop in and out of monitors or if we're really stuck we use a special 12V splitter so the signal is not degraded. But when can I use a T connector or whatever they may be called? Do they have to be plugged in a special way with the video in at the pointy end or what??? Are they only to be used on short runs? Is there much signal lost? Is it ok to use them on a professional install? I'm only asking because I dont know anything about them! Trade Member Link to comment Share on other sites More sharing options...
bri Posted July 18, 2005 Share Posted July 18, 2005 AH HAAAA!!! We promote a product that requires the use of a t connecter. Its a video smoke detection system that picks up smoke faster than conventional smoke detectors and retrofits into existing cctv systems or we will provide cctv system and fire system in one.No signal loss and no other loss. Anyone got customers who might be interested get in touch with me and we will provide a demo or site visit. Bri Link to comment Share on other sites More sharing options...
Brian c Posted July 18, 2005 Share Posted July 18, 2005 I've used the T, F and straight through connectors now and again. I've heard other people say they can cause problems with poor connections/signal loss, but I've never had a problem with them. Put a bit of tape round them if you're using them for a join. If you don't know......ask. Link to comment Share on other sites More sharing options...
Adi Posted July 18, 2005 Share Posted July 18, 2005 Anywhere you want to mate. Obviously the less connections the better but ive used them with no side effects. On one job a camera is teed off to a monitor while the signal carries on to the video and another monitor. I really can't be ar**** with it anymore.

Nova-Security Posted July 18, 2005 Share Posted July 18, 2005 Just make shure that you only have one 75ohm termination, if spliting for monitors make sure one is on Hi Res and the last one on 75ohm termination. www.nova-security.co.uk www.nsiapproved.co.uk No PMs please unless i know you or you are using this board with your proper name.

norman Posted July 18, 2005 Share Posted July 18, 2005 As above, the 75 ohm resistor basically buffers the signal, (it's going quite fast!) I don't do CCTV install anymore but I used to heat shrink any straight through joins. Nothing is foolproof to a sufficiently talented fool.

ian.cant Posted July 18, 2005 Share Posted July 18, 2005 Avoid T-piece connectors if you can, as you will most probably not be able to correctly terminate the signal. As you say loop-thru's are common place these days, especially on monitor's and most kit will auto terminate the signal so if you use a T-piece you dont have a single end of line, you have 2 and therefore 2 terminations. I cant think of the correct terminolgy for the effect this will cause but your picture will be very bright and you may not be able to do much about it. Unless you have termination switches or control of the termination one way or another. They do have a place but these days those places are rare, avoid them if you can.
