History — Alarms

← Manual

The Alarms history section is a searchable, paginated log of all alarm incidents recorded by the system. Each alarm groups the suspicious events that triggered it and shows who acknowledged it.

For live alarm management (the floating alarm window, Arm/Disarm controls), see the Overall Layout & Global Controls page. For configuring which events trigger alarms per device, see Devices — Device Alarms tab.

Filter Bar

Clicking the filter bar opens the Filter Alarms Dialog.

Filter Alarms Dialog

Field Description
Devices Filter to alarms triggered by specific devices
Event Type Filter to alarms involving specific event kinds
Time From Lower time bound
Time To Upper time bound

Alarm List

Each alarm is shown as a collapsible accordion entry:

Collapsed — shows the alarm timestamp, event count chip (e.g. “3 Event(s)”), and an “Acknowledged by [user]” chip if the alarm was acknowledged.

Expanded — shows a stack of triggering event rows, each with:

  • Event description (kind + source device)
  • Event timestamp

Clicking a triggering event row opens the Event Detail Panel for that specific event (the same panel used in History — Events).

Live Alarm Floating Window

When an alarm is actively firing and has not been minimised, a draggable, resizable floating window appears over the entire UI. It cannot be blocked by other dialogs.

Window Controls

Control Description
Do Not Disturb toggle Silences the alarm sound while the window stays visible
Dismiss Hides the window; alarm remains active and the notification badge persists
Acknowledge Marks the alarm as acknowledged; clears the active alarm state

Triggering Events (inside the window)

Each triggering event is shown in an expandable accordion. Expanding an event loads associated camera feeds in a twin view showing:

  • Live feed — current camera view
  • Playback — seeked to the exact event timestamp

Arm / Disarm

The Arm/Disarm button in the app bar controls whether “trigger-when-armed” alarm configurations are active across all monitored devices.

State Behaviour on Click
Devices are armed Disarm all
No devices armed Arm all
Armed with bypassed devices Opens a status popover; arm/disarm still available

The button shows counts of armed vs total devices.
