The ZKR Central Monitoring Software is a web-based monitor that observes all activities such as nurse calls, code blue (and any custom emergency codes), assist calls, and nurse presences throughout the hospital. It can show picture IDs of personnel that are present in patient rooms. Different parameters (call type, department, and floor info) can be filtered based on needs. In this way, the focus of health personnel can be directed and reaction and intervention times can be minimized.
