Hi first time poster........ I'm installing an AV system for someone at the moment and the guy who installed his CCTV has vanished. He's installed an 8 channel AV tech server with 6 cameras attached. This is a mac household apparantly. I;ve tried installing the cctv_1.0 program and it works fine........but only for 4 cameras. am I missing something. Apologies for posting this in what is clearly a PC forum, but I didnt know where to put it! Regards Loggo
