Hello guys Im using a gv-800 card for cctv video, and now i want to add cctv audio to one of my cameras.... locally i have access to this mic: imgur. com/DzAzM.jpg (join the U RL, couldnt post urls because im new ) i would ignore the video cable, as my cam is already wired with siamese rg59 What cable should i run from my GV800 to the mic? can i run the standard cctv video siamese cable, cut the mics power & audio and patch them?

hello guys last year i installed my cctv system based on a pci gv-800 12ch card... with the new 8.3 software i want to add another 16ch gv-800 card.... how can i know if my current card is compatible with dual cards mode? im running 8.2 now.... thx in advance Greetings
