Hello, 
  
I was told and by trying it myself this digital wireless receiver is not compatible with this DVR attached to one of it's video channels.  I don't get any picture from the camera.   
  
I imagine the composite signal from the RCA is not in a compatible format the DVR can handle.  Not sure what it's sending out from that receiver that only a tv or monitor can display.  But would anyone know or is there any modulator or adapter I can use to convert this signal to something the DVR can interpret and display? 
  
Thanks for any help
