Need help with CCTV video interference in Video Transmission/Control Devices Posted June 7, 2021 Yes I’m using bnc plugs. Yes. We have over around 80 cameras in 3 floors and in each floor we have 2 jumble boxes like this one (https://www.surveillance-video.com/accessory-rj860ap.html?gclid=EAIaIQobChMI5N3Gk_GE8QIVyhitBh3EEwpyEAQYBCABEgIYafD_BwE) but bigger for the Ptzs. For the stills we use a different one that connects the red and black cable and has a fuse. when I was testing the ptz I used a jumble box that we have in our camera room but no other camera uses this jumble box for power.
