KevinE Posted August 25, 2010 Share Posted August 25, 2010 Hello, Im looking to extend a covert body-worn bullet camera cable which uses a 4-core (3 core plus screen really) cable. It is terminated in a 2.5mm 4-pole jack plug to go into a solid state recorder, I have a plug and socket so I can make up a mini extension lead.The problem is getting the cable; its only for a 1.5m metre run, so 75R low-noise stuff isn't needed (I doubt what's fitted is, either). The original fixed cable is only 2mm in outer diameter, I dont want much bigger as I won't reliably terminate it in the tiny connectors I've got. Cheers, Kevin Link to comment Share on other sites More sharing options...
sleah Posted August 26, 2010 Share Posted August 26, 2010 Does it definately have to be screened? If not, flexible telephone/alarm cable will do the job :unsure: You may get away without the screen for a short run, could be worth experimenting....

Robin Pratt Posted August 26, 2010 Share Posted August 26, 2010 CPC do a screened version of the 4 core alarm cable, CB11431, but its 4mm dia so may be too tight..... Alternatively you could use something like lavalier mic cable from Mogami or similar, but its "tinsel" conductors so will be an absolute **** to solder Link to comment Share on other sites More sharing options...
dbuckley Posted August 27, 2010 Share Posted August 27, 2010 Depending on your level of desperateness, buy a low cost CCTV camery from B&Q, and these come with many meters of cable, which I believe will match your specification. Link to comment Share on other sites More sharing options...
musht Posted August 27, 2010 Share Posted August 27, 2010 Depending on your level of desperateness, buy a low cost CCTV camery from B&Q, and these come with many meters of cable, which I believe will match your specification. Not so sure, usually `shotgun` cable twin core screened side by side with power. Over any range baluns and Cat5 cheaper. Anway 4pole 2.5mm common phone headphone connector, 2.5mm f-f extension rare but possibly butcher one of the 2.5mm-3.5mm or phone adaptor cable?

dbuckley Posted August 27, 2010 Share Posted August 27, 2010 Not so sure, usually `shotgun` cable twin core screened side by side with power.Having just had a dig in the garage, the "Micromark" brand cameras I have (E2a: these) use a single cable, not a shotgun, and its about the same diameter as four core alarm cable. Shotgun (power and video seperate) cable is more upmarket than I am suggesting, these are cheap cameras. Link to comment Share on other sites More sharing options...
Jivemaster Posted August 28, 2010 Share Posted August 28, 2010 What sort of duty does the lead have to withstand? Could you pull some lengths of enamelled copper wire up some heatshrink? Maybe twist one pair for noise rejection. My local shop sells heatshrink in 1.2m lengths. I had some maplin leads that worked well when installing board and bullet cameras they were just 4 core "alarm wire" from scart plug to bare ends. they were supplied at 20metres long and worked fine - no attempt at 75R or screening!

Silvie Posted August 29, 2010 Share Posted August 29, 2010 For a 1.5 metre run, I would use anything.......... BT cable, alarm cable, cat5, bell wire, speak wire.... anything will work, picture quality and voltage will be fine.... Paul. Link to comment Share on other sites More sharing options...
KevinE Posted August 29, 2010 Author Share Posted August 29, 2010 The plugs will not physically accept anything much bigger than 2 or 3mm total outside diameter cable. In the end, I found a duff mini laptop mouse and cut the cable off that, it was just long enough. Link to comment Share on other sites More sharing options...
