The camera is directly connected to the computer, and there is no hard disk recorder.

Standard answer: Today's hard disk video recorders have vga and composite video output. Look at the interface behind your TV. If it is a flat-panel TV, you need a vga cable (public to public) to connect the TV and the hard disk video recorder. You can see the monitoring picture on the video recorder on TV. If it is an old TV with a picture tube, there is usually a composite video interface (the yellow one) behind the TV, then you can connect it to the composite video output behind the hard disk video recorder with a bnc-Lotus connector, and then connect the TV with the hard disk video recorder with a video cable with Lotus street at both ends (where there are electronic accessories).
