zacapa07 0 Posted May 6, 2013 Hi All, I'm new- bear with me...? I just bought 2 security camera systems with 4 cameras each. Is it possible to join/combine the video outputs from both DVR's (BNC connections on DVR's) and run them through a single RG6 to a TV monitor? Thanks for assistance!

survtech 0 Posted May 18, 2013 Actually, there are a few of ways to do that: 1. FM Systems makes a couple of "Video Diplexers" that will combine two analog cameras to one cable. Not cheap: http://www.fmsystems-inc.com/cw/Details.cfm?ProdID=95&category=17 PS - you need both a transmitter and a receiver. 2. They also make a Remote Controllable A/B Relay Switch. You'd still need to get 24VDC from the monitor's location to the switch (possibly do-able over the coax): http://www.fmsystems-inc.com/cw/Details.cfm?ProdID=206&category=17 3. Another possible way, but at the sacrifice of some image quality. Two RF Modulators and a signal combiner. You put them on separate channels and tune the TV back and forth: http://www.linearcorp.com/product_detail.php?productId=171 All of the above assume you want to feed "baseband composite" analog video and don't mind switching the TV back-and-forth to see either DVR. Otherwise, your choices are nil. Share this post Link to post Share on other sites
