I have bought a second hand Defeway DVR ri connect it my garden feeder bird camera. I have set it up and can get the Defeway operating fine on the screen (small tv) I am using but cannot get the camera image to show.mi can get the image on the TV when not using the DVR. I have run a VGA cable between DVR and TV. I have tried different ways of connecting t the camera to either the TV and directly to the DVR but to no avail. any tips for me to try.
