ayalas 0 Posted July 30, 2007 I think i have the idea now on how to do this , but now my question is would you need some permishion from the cable company? Its for a 3 floor building i already installed 4 cams and the clients would like to see just one of them on there tvs the one at the front gate for visitors. thanks...

survtech 0 Posted July 30, 2007 I assume this is in a business building? Does the client own /lease the whole building? If so, you could probably use a notch filter to remove one or more channels and insert the video there with a RF Modulator and a combiner. Check with CATV distribution manufacturers for details. The main concern for most cablecos would be that your camera signal doesn't backfeed to their system. There are products to prevent this. Share this post Link to post Share on other sites
