Monitoring Station Operator Guide
This guide covers the essential workflows and features for Alarm Receiving Centre (ARC) and remote monitoring station operators processing events in TetherX.
Getting Started
Choosing your View
TetherX offers two view modes for processing events:
- List View - Displays events in a compact table format with timestamps, site names, camera names, and event details. Recommended for monitoring operators as it allows sequential processing and shows more events on screen.
- Thumbnail View - Displays events as image thumbnails in a grid. Useful for visual scanning but less efficient for high-volume processing.
Most operators prefer List View for systematic event processing. Switch between views using the icons in the view menu.

Processing Events
Event States
Understanding event states helps you track your workflow:
| State | Description |
|---|---|
| Open | New events requiring attention |
| Pending | Events currently being viewed by an operator - prevents multiple operators reviewing the same event. Clears after 3 minutes of inactivity |
| Closed | Events that have been reviewed and closed by an operator |
| Hidden | Events still recording in the background, but not shown in the open events list or monitoring strip |
When you open an event to review it, the system automatically marks it as Pending for 3 minutes. This prevents other operators from duplicating your work and indicates you're actively reviewing it.
Sorting Events
Tip: Select today's date in the left sidebar date picker to sort events ascending from oldest to newest. This helps process events in chronological order, ensuring older events don't get missed.
Bulk Selection
You can select multiple events at once to perform bulk actions such as closing or hiding several events simultaneously.
Drag to select: Click and drag a selection box across multiple events to select them all at once. This works in both List View and Thumbnail View.
Other selection methods:
- Use the Select dropdown in the view menu to bulk select events by time period (e.g., last hour, today)
- In List View, use the checkbox in the header row to select all events currently visible on screen
Tip: Press Escape to quickly deselect all selected events.
Once events are selected, use the bulk action buttons to close, hide, or perform other actions on all selected events at once.
The Monitoring Strip
When you close an event that still has active analytics or motion, it moves to the Monitoring Strip on the right side of your screen instead of disappearing immediately.

How It Works
- Events remain in the monitoring strip for a configurable period (default 5 minutes) before automatically closing
- A countdown timer shows time remaining for each event
- Events are sorted oldest first by default (closest to expiring at top)
- In the final 30 seconds, the countdown pulses red - giving you a chance to double-check nothing important is happening
Activity Alerts
- Events flash whenever new analytics are detected (person, vehicle, motion)
- This draws your attention to sites with ongoing activity that may need reopening
- Click the reopen button to bring the event back for full review
Tip: The monitoring strip helps you catch important activity that occurs just after you close an event - such as a person returning or a vehicle entering after initial movement.
Live Preview Features
Live Camera Preview on Hover
In List View, hover over the camera icon next to a site name to see a live preview of what's currently happening on that camera.

This is useful for:
- Quickly checking if activity is ongoing before opening the full event
- Verifying the camera is operational
- Getting context before reviewing recordings
Live Thumbnail Toggle
Enable Live Preview in the view menu to replace static event thumbnails with live camera feeds for any event still in progress.
- Shows real-time footage instead of a captured moment
- Helps identify ongoing incidents
- Automatically reverts to static thumbnail when the event completes
Controlling Event Flow
Pausing Real-time Updates
When processing a backlog of events, use the Real-time toggle in the view menu to temporarily stop new events from appearing.
This helps you:
- Focus on existing events without interruption
- Process events systematically without the list shifting
- Catch up during busy periods
Warning: Remember to re-enable real-time updates when you've cleared your queue. New events will still be recorded - they just won't appear until you toggle it back on.
Site Notes
Site notes contain critical information for responding to events at specific locations. They typically include:
- Site address and cross streets
- Monitored hours
- Keyholder contact details
- Emergency response procedures
- Priority cameras and special instructions
- Site maps and access information
Viewing Site Notes
Look for the notes icon next to the site name in the event row. Click or hover to view the notes in a popover.

Reporting Issues
If you experience glitches, slowdowns, or unexpected behaviour while processing events, please report it so we can investigate. TetherX includes ARC Slowdown Diagnostics - internal tooling that helps our support team quickly identify and resolve performance issues in control room environments.
ARC Performance Report
For monitoring station performance issues, use the dedicated ARC Performance Report form on our support page. This form collects all the diagnostic information we need to investigate quickly.
Before submitting, have the following information ready:
| Information | Example |
|---|---|
| Time window | 14:20-14:30 (5-10 minute window when issue occurred) |
| Date and timezone | 23 Jan 2026, GMT |
| Affected sites | ABC Warehouse, XYZ Industrial Park |
| Speed test results | Visit speedtest.net - note download, upload, and ping |
| Workstation specs | Windows 11, Chrome v120, 16GB RAM |
| Screenshots | Full-screen capture showing the issue |
How to Report
- Visit the support page
- Click Report Performance Issue to open the ARC Performance Report form
- Fill in the required fields - issue type, time window, and description
- Add optional diagnostic information (speed test, workstation specs)
- Attach any screenshots showing the issue
Tip: For intermittent issues, note approximately how often they occur and any patterns you've noticed (e.g., "happens during busy periods" or "only affects certain sites").
Warning: If the issue relates to a specific site or event, include the site name and a link to the affected event in your report. This helps our team investigate the exact data you were viewing when the problem occurred.
