Q-SEE QS50B 50' BNC Male Cable with 2 Female Connectors

Comment:
I wish they'd have a smaller cable as in length, but this will do just fine as it extends my camera's distance from the base, excellent cable, high quality.

I used one of these to extend an outdoor run (combined it with the 60' from the Q-See kit). No problems installing it, and no problems with video quality either. As the description indicates (but the photo does not) it comes with BNC gender changers so you can use it as an extension and not just a replacement cable, it also comes with a small extension for the power cable though I never needed it. Cable is white as shown, not black like the original cables from the Q-See camera kit. As cables they aren't cheap, but you couldn't make your own for much less if you only need one or two.

I have one of the lorex systems that runs through a pc as well as one of the dvr systems from q-see, these extension cables are way cheaper than those from lorex and the setup is way simpler for the q-see as well.
