cctvman123 0 Posted June 9, 2015 Hello all... I have one of those cheap import video security dvr's that has a hdmi video output to view my video cameras. I have verified that the hdmi cable is good, the connection to a tv with hdmi is good and able to display the security cameras and the hdmi in port on the slingbox 500 is good. It comes down to the connection from the security dvr to the slingbox not recognizing the video. The slingbox just does not show anything. Would anyone know what could be causing this issue? Does anyone really know what these import hdmi dvr really output? Share this post Link to post Share on other sites
