Hi , to start with check if your DVR can take IP cameras - most new DVR allow limited IP cameras to be connected. Preferably get the same brand IP camera or if not the same brand ensure that both the DVR/NVR and Camera are ONVIF compatible. Use a IP sniffer or software supplied with the Cam to change the IP and connect the cam to a switch which in turn connects to network port on the DVR/NVR. Search for the IP cam on the DVR/NVR and add it to the table.
