Abstract

A method for decreasing the risk of monitoring data failing to be stored includes periodically sending a test message from the monitoring device to a Networked Storage Device, NSD, generating an NSD fail signal in the monitoring device if events following the sending of the test message indicates that the NSD is not operating properly, and sending, in response to the NSD fail signal, a fail message from the monitoring device for detection outside housing of monitoring device.
