Good Morning, 
Did a search but couldn't find an answer. 
I purchased a home that is wired with Q-see connectors.  I have a Samsung DVR and camera. 
Is there an adapter to use the existing Q-see wiring with Samsung cameras and DVR?  The connectors are different. 
  
My issue is that all the wiring is inside the walls and I have no access to run new ones to certain spots. 
  
Any help?
