PaulsonLaw 0 Posted January 25, 2012 Just wondering if anyone has ever ran a camera video signal down a current active internet cable... TC-L2 cat5, 300' run thanks Share this post Link to post Share on other sites

musher 0 Posted January 25, 2012 I think he's talking about using the unused pairs to host an analog signal. Might be a trick to do a neat installation at either end. Need to split out the pairs with different functions. It's done successfully with phone signals, I have no idea whether the analog video signal would induce errors in the data pairs. Test it and let us know! PS-- I assume you're running 10 or 100MB here. Gigabit uses all the pairs. Share this post Link to post Share on other sites
Soundy 1 Posted January 25, 2012 Yeah, it's theoretically possible, since 10/100 ethernet uses only two pairs (orange and green). You shouldn't see any interference in the video because the data signal is very low power and the video line will be balanced (assuming you're using baluns). I wouldn't expect the video signal to cause issues with the data either, as again, it's very low power, and the different twists in Cat5e/6 are specifically there to prevent crosstalk between pairs.

PaulsonLaw 0 Posted January 25, 2012 I am not worried about the video crosstalk on the TC-L2 cable, great stuff, best made for shielding I am sure.... Not running giga so you say just leave the orng & grn pairs alone huh? Splicing not an issue as where this line comes in to both locations, it has the regular "press in" female ends & runs a short patch to the dvr & the router. Yes, my dvr & router are 100's of feet apart lol. But whats the point in a dvr if someone would find it & steal it lol. Let me know what pairs to remove from the female cat5 ends plza Share this post Link to post Share on other sites
musher 0 Posted January 25, 2012 Pins 123 and 6 are used for ethernet. The colors of the unused pairs may vary depending on how your cable is wired. Look up tia/eia 586a/b Share this post Link to post Share on other sites
Soundy 1 Posted January 26, 2012 I am not worried about the video crosstalk on the TC-L2 cable, great stuff, best made for shielding I am sure.... Jacket shielding really isn't relevant, since the pairs are all inside the same shield... Not running giga so you say just leave the orng & grn pairs alone huh? Well, assuming standard T-568A/B wiring... as musher notes, some cable may use different colors, but those are the most common (the others being blue and brown pairs). If it were me, I'd probably be punching down to a keystone jack in this case, and just leave the blue and brown pairs out - split them off and splice the video run(s) to them directly, or connect them directly to baluns.
