Very cool. Is there a recommended 5in1 DVR to buy - and what should I be looking for in the camera spec to ensure I can switch it over and utilise the coax? Are adapters required to go from the co-ax to the camera etc? I am looking for help as to which DVR and cameras to buy … and also need a replacement camera in the gate control etc. Do hikvision have the 5:1 DVR, cameras and gate control / camera that are all compatible?? Thanks so much
