  1. This isn't really an issue im bothered about, just wondering whats going on. PTZ (on my house) with a powered mic (from amazon) that jumps the 12vdc power to the camera. https://www.amazon.ca/gp/product/B0769RYBTB/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 When the PTZ moves Zebra bars roll across the screen. Solution was to disconnect the ground from the mix so only the signal runs back to the DVR, No Zebra lines! I tried ferrite blocks on each cable at different locations, didnt work. Does a Mic only need the signal wire to work, ever? Any thoughts?
