Hello guys! I'm new here and I am hoping I can find a little bit of advice. I have been installing surveillance systems for about 4 years and I have never had a customer request this before. They would like for the dvr to be view-able on every tv in the home. They have direct tv and everything is ran to a structure box in the basement with all of the splitters. I was going to set up the dvr beside the structure box and was wondering if you can feed the video signal into the direct tv system in some way. They would basically like to go to each tv and change it to a channel and see the cameras. I am familiar with all cctv related terms and I have retro fit lots of things and completed some crazy projects, but this is uncharted territory for me. If anyone has advice I would GREATLY appreciate it. Thanks guys!!
