Hello, Apologies if this question has already been asked, hopefully you could point me into the right direction I have a Swann DVR box and Sky HD connected to my main tv in the living room and want to show the CCTV on all TV's whilst still being able to use the magic eye. Currently I use the RF output from the Sky HD box which goes into the coax wall socket which goes to my loft. In my bedroom i have another coax wall point which meets in the loft. I have simply linked these two "loose wires" together in the loft to create a loop to the bedroom allowing me to watch sky upstairs. My question, how do i make my TV in the bedroom show CCTV aswell? Would a Y splitter work in the living room? Thanks
