•Click on the Event Log icon in the header of the Notification Panel

Events are displayed in the following columns. You can click on any column header to sort the log in ascending or descending order:

•Date/Time – date and time the event occurred

•Event – the type of event

•Source – the resource that initiates the event: device (motion detection, input signal, etc) or server (storage failure, server failure, etc).

•Action – the action that is performed when the event occurs.

•Target – the Users or Devices that are recipient of the action.

•Description – any additional information. For motion detection events, the description includes a hyperlink that will open the device in a new layout and start playback of the event.
