Friend of mine lives in apartment building. He has security cameras feed coming from that coxial cable that he can directly connect behind his tv and view his lobby. Question is that he wants to record that feed and hows that possible?
He ordered cctv dvr and hooked up that coaxial cable but dvr shows black screen. Does he need any converter or what will be the setup? He does not want to hook it up with pc so what can be done in order to record with dvr or is theres any other small device where he can record. Thanks
