    Hello all I currently use a night owl system and the cameras take bnc connecters. I have noticed on the cameras that I added length to them I think its effecting the video picture. I got some 100 foot wires off Amazon but think it is causing a poor picture.

    Any way to do custom length wires at home?

    I know this is super late but if you are still working on this :)

    Yes, cheap cables can cause all kind of artifacts in the picture quality of HD video CCTV cams. Making your own cables (especially for long runs) is best for avoiding the issues with cheap premade cables.
    The cable is easily found everywhere - it is an RG59 designed for base band video (solid copper center, 90-95% copper braid), that is siamese with an 18/2 for power.
    Avoid getting cheap cable that is not solid copper center. Copper clad steel or aluminum (many times seen as CCS, CSS, CCA...) is stiffer, harder to work with (which can cause issues in the installation of the cable) and higher loss per foot. By the way, as of 1/19/2020 doing a general search on Amazon.com showed no good CCTV cable. It was all claded junk other than a $200+ spool.
    Luckily Walmart of all places has some right now for only $73.50 for 500ft.: https://www.walmart.com/ip/VideoSec...ance-Cable-for-Security-Cameras-cqz/151045588

    For the ends, I like using Belden's BNC compression connectors. They are available on amazon: https://www.amazon.com/RG59-BNC-Connectors-25-Pack/dp/B00BYE9MX2/
    You will also need to get a compression tool to put the ends on. There are a lot of cheaper BNC compression ends you can buy. Having tried many of them, some are OK but aggravating to put on. While others are just junk. YMMV.

    Something else you might want to think about. Use Cat5e or Cat6 instead. You use baluns at the ends of the cable to send/receive power & BNC video. And if you ever decide to switch to IP cameras, it makes it super simple. https://www.amazon.com/dp/B01BH2O550/
