Since the VA2CS system is interoperable with the majority of patient call systems on the market, the staff can receive alerts on their DECT terminal, only the no-image alert is received. If the staff is equipped with a smartphone with the VA2CS application, they will receive the alert with the associated image. At all time, all alerts can be gotten from a computer in the nurses’ room. It is possible to broadcast the alerts to certain staff, according to criteria, for example: 1st floor alerts for the staff responsible.
