VSS Reference User Interface#

Overview#

The major functionalities are encapsulated Tab-wise. Tabs represent the major functionalities of the UI and can be enabled/disabled based on the deployed blueprint/profile. Below the list of tabs on the main left sidebar, exists the controls pertaining to the current tab.

Each tab is described in detail in its respective section below.

The UI provides a global Chat sidebar to interact with an agentic backend service (if the service is deployed). This Chat sidebar is available across multiple tabs (Search, Alerts, etc.) and provides a more integrated experience.

The UI supports both dark and light themes. To change the theme, click the theme toggle button in the top right corner.

Global Chat Sidebar#

Note

The Global Chat Sidebar replaces the separate Chat Tab that previous VSS use cases and workflows relied on. The Chat Tab is no longer actively documented from this release on. You can still enable either surface at deployment time through environment variables on the UI service. For the sidebar, use variables matching NEXT_PUBLIC_(ENABLE_CHAT_SIDEBAR|CHAT_SIDEBAR_.*|SIDEBAR_CHAT_.*). For the legacy Chat Tab, set NEXT_PUBLIC_ENABLE_CHAT_TAB and the other NEXT_PUBLIC_* variables.

VSS Reference User Interface - Global Chat Sidebar - Icon to Open

The Global Chat sidebar can be opened by clicking the Chat icon at the bottom-right corner of the screen as shown above.

The Global Chat Sidebar is a persistent, collapsible chat panel available across multiple tabs (Search, Alerts, etc.) that provides direct access to the Agentic backend service without navigating away from the current view.

VSS Reference User Interface - Global Chat Sidebar

Toggle:

  • Click the chat icon at the bottom-right corner of the screen to open.

  • Click the minimize button on the left edge of the sidebar to close it.

  • The sidebar is resizable by dragging its left edge (between 1/3 and 2/3 of the content area width)

Key Features:

  • Natural language conversational interaction with the Vision Agent

  • Video upload for agent analysis (drag-and-drop or click to browse; MP4, MKV supported)

  • Context-aware queries — attach video clips from search results or alert metadata as context using the “+ Chat” button on video cards or the “Generate Report” button in alert rows

  • Agentic query results are reflected directly in the current tab’s content area (e.g., search results populate the Search Tab grid), if applicable.

  • Chat history with new-conversation and folder-organization support

  • Unseen response indicator (orange border on the “Chat” tab) when responses arrive while the sidebar is collapsed

  • Send applicable agent parameters (supported based on the deployed blueprint/profile) along with the query to the agentic backend service.

  • Preserve the conversation context while working across multiple tabs.

Chat Input#

Type your question in the input box at the bottom of the sidebar. Press Enter or click the send button to submit the query to the Vision Agent. The agent processes the query and streams the response in real time.

For streamed responses, each answer card includes an “Insights” component that shows the intermediate steps of the agent’s reasoning as the response is generated.

VSS Reference User Interface - Global Chat Sidebar - Insights

VSS Reference User Interface - Global Chat Sidebar - Agent Parameters

When the current deployment defines agent parameters, an Agent Parameters control appears in the chat input bar (to the left of the send button). Click it to open a popover, set the supported values, and submit your query. The selected parameters are sent with each request to the agentic backend service.

The available fields depend on the deployed blueprint or profile. For example, a search deployment may expose Search media source type and Enable Critic; a base profile may expose reasoning toggles. If no parameters are configured for the deployment, the control is not shown.

Note

Configure sidebar agent parameters at deployment time with NEXT_PUBLIC_SIDEBAR_CHAT_CHAT_API_CUSTOM_AGENT_PARAMS_JSON on the UI service. Set the value to a JSON object with a params array. Each entry supports name, label, type (boolean, string, number, or select), default-value, optional options for select, optional changeable (defaults to true), and optional tooltip-info.

Video Upload#

VSS Reference User Interface - Global Chat Sidebar - Video Upload

The Chat Sidebar supports uploading video files for analysis by the Agent.

  • Drag and Drop: Drag video files directly into the upload area

  • Click to Browse: Click the upload area to open a file browser

  • Upload Button: Click the upload icon button next to the chat input box

  • Supported Formats: MP4, MKV

After uploading, the agent can analyze the video content and answer questions about it.

Note

Upload functionality through the Chat Sidebar will not be available if disabled in the deployment scripts.

Controls/Settings Panel#

VSS Reference User Interface - Global Chat Sidebar - Chat Controls Open Close Icon

The collapsible left side panel inside the Chat Sidebar contains chat controls:

  • New chat: Start a new conversation

  • New folder: Create a new folder to organize conversations

  • Search: Search through existing conversations

  • Chat History: List of previous conversations (shows “No data” when empty)

  • Export data: Export conversation data to a file

  • Import data: Import (a previous exported) conversation data from a file

  • Settings: Open the settings dialog

The settings dialog allows you to configure:

  • “HTTP URL for Chat Completion” — The URL of the agent query HTTP endpoint.

  • “Websocket URL for Chat Completion” — The URL of the agent query websocket endpoint.

  • “Websocket Schema” — The schema of the agent query websocket endpoint.

  • “Enable Intermediate Steps” — Show or hide the “Insights” component in the response.

  • “Expand Intermediate Steps by default” — Auto-expand the hierarchy in the “Insights” component.

  • “Override intermediate Steps with same Id” — Show nested hierarchy view of agent call sequences.

Interaction with Tabs#

The Chat Sidebar integrates with different tabs: Example flows are:

  • In the Search Tab, when the sidebar is open, manual search controls are disabled. Queries submitted through the sidebar trigger an agentic search, and matching video results populate the Search Tab’s content area. Use the “+ Chat” button on video cards to attach clip context to the sidebar input (see + Chat Button).

  • In the Alerts Tab, use the “Generate Report” button in an expanded alert row to send alert metadata to the Chat Sidebar for AI-powered analysis.

  • Video/Sensor related context can be added to the chat input by clicking the “+ Chat” button on video/sensor cards in the Search Tab, Video Management Tab.

Unseen Response Indicator#

When a response arrives while the Chat Sidebar is collapsed, the Chat icon shows an orange border to indicate unseen content. Clear the indicator by:

  • Opening the Chat Sidebar — viewing the content marks it as seen.

  • Clicking the cancel button on the orange border — marks content as seen without opening the sidebar.

Tabs#

1. Alerts Tab#

The Alerts Tab provides a complete interface for monitoring, investigating, and managing AI-detected incidents. It is organized into two views accessible from the left sidebar:

  • View Alerts — Real-time monitoring dashboard for viewing, filtering, and investigating detected incidents.

  • Manage Alerts — Configuration interface for creating and managing real-time alert rules.

  2. Alerts Table — Sortable, paginated table with video playback and metadata

Filter Controls#
VLM Verified Toggle#

Filters alerts by VLM verification status:

  • ON 🔵 = Show only VLM-verified alerts

  • OFF ⚪ = Show all unverified alerts

Verdict Filter#
VSS Reference User Interface - Alerts Tab - Verdict Filter

Visible only when VLM Verified is ON. Options:

  • All

  • Confirmed (true positives)

  • Not Confirmed

  • Rejected (false positives)

  • Verification Failed

Sensor / Alert Type / Alert Triggered#
VSS Reference User Interface - Alerts Tab - Sensor / Alert Type / Alert Triggered Filter

Three dropdown filters for narrowing results:

  1. Click a dropdown → Select a value → A filter tag appears below

  2. Click ✕ on a tag to remove it

  3. Quick add: Click sensor, alert type, or alert triggered values directly in the table rows to add them as filters

Filter Tags: Color-coded badges (🔵 Sensor • 🟠 Alert Type • 🟢 Triggered). Multiple filters use AND logic.

Alerts Settings#
VSS Reference User Interface - Alerts Tab - Alerts Settings

Click the gear icon (⚙) in the filter bar to open the Alerts Settings popover. This popover contains:

Query Range:

Controls the time window for fetching alerts from the API.

  • Preset options: 10 min (default) • 20 min • 30 min • 1h • 2h

  • Custom: Select “Custom” to enter a specific duration. If a maximum search time limit is configured (via NEXT_PUBLIC_ALERTS_TAB_MAX_SEARCH_TIME_LIMIT), the custom value will be capped accordingly. A value of 0 means unlimited.

Tip: Shorter query ranges load faster and reduce server load.

Fetch Size:

Controls the maximum number of alerts returned per API call.

  • Preset options: 50 • 100 • 200 • 500 • 1000 • 2000 • 5000

  • Custom: Select “Custom” to enter a value between 10 and 5000

Note: Higher fetch sizes may result in slower API responses. The fetch size also determines when the “Load More” button becomes available — if the API returns a batch equal to the fetch size, more data may be available.

Refresh Controls#
VSS Reference User Interface - Alerts Tab - Refresh Controls

Auto-Refresh (↻ icon): Configurable intervals — 1s / 5s / 10s / 30s / 1min. When enabled, the icon turns blue with a pulsing dot indicator.

Manual Refresh (🔄 icon): Click to refresh data immediately. The icon spins while loading.

Best Practice: Use 1–5s intervals for active monitoring, 30s–1min to reduce load, and disable auto-refresh during detailed analysis.

Alerts Table#
VSS Reference User Interface - Alerts Tab - Table Overview

Table Toolbar#

The sticky toolbar above the table header provides:

  • Alerts displayed — Total count of alerts matching current filters

  • Pagination summary — Shows “Page X of Y · Showing start–end” when pagination is active

  • Rows per page — Control how many rows are displayed per page. Presets: 10 • 20 • 50 • 100 • 200 • 500, or enter a custom value (1–500)

  • Time display — Toggle between Local time and UTC for timestamps shown in the table

  • 3rd click = Reset to default ⇅

Pagination#
VSS Reference User Interface - Alerts Tab - Table Pagination

The table supports client-side pagination:

  • Page navigation — Previous/Next buttons and page number buttons with ellipsis for large page counts

  • Rows per page — Adjustable from the table toolbar (presets: 10, 20, 50, 100, 200, 500, or custom 1–500)

  • Auto-reset — The table automatically returns to page 1 when filters, query range, VLM settings, page size, or sort order change

Load More Alerts#
VSS Reference User Interface - Alerts Tab - Load More Alerts

When additional data may be available beyond the current fetch size, a “Load more alerts” button appears at the bottom of the last page.

  • The button shows the batch size: “Load more alerts (up to N)”

  • Clicking it fetches older alerts and appends them to the existing dataset

  • Auto-refresh must be disabled to use Load More — a tooltip explains this when auto-refresh is active

  • After loading more alerts, the table resets expanded rows and sort state while preserving the current view

How it works: The Load More function queries for alerts older than the earliest alert in the current dataset. Results are merged and deduplicated by alert ID.

Expandable Rows#
VSS Reference User Interface - Alerts Tab - Expandable Rows

Click ▼ or ⓘ to expand a row and view its Metadata section.

Available actions in expanded rows:

  • Generate Report — Sends alert metadata to the Global Chat Sidebar for AI-powered analysis (available when a report prompt template is configured). The Chat Sidebar opens automatically with the alert context pre-filled, allowing follow-up questions about the incident.

  • Copy Report Prompt — Copies a formatted template with metadata for AI analysis to clipboard

  • Copy Metadata — Copies the complete JSON metadata for debugging or sharing

All copy actions show a visual confirmation.

Video Playback#
VSS Reference User Interface - Alerts Tab - Video Playback

Click the thumbnail or play button to open a video modal with Play/Pause, seek bar, volume control, and fullscreen support.

Requires: Sensor mapping, VST service, and network connectivity.

Manage Alerts#

The Manage Alerts view provides an interface for creating and managing real-time alert rules. These rules configure the alert bridge service to detect specific events on live video streams.

VSS Reference User Interface - Alerts Tab - Manage Alerts Overview

Requirements: The Manage Alerts feature requires the Alerts API URL to be configured (NEXT_PUBLIC_ALERTS_API_URL). Without this, the view will display an error.

Alert Rule Kinds#

The Manage Alerts view has tabs for different rule types:

  • Real-time Alerts — Active and fully functional. Configure rules that process live video streams.

  • Alert Verification — Coming soon (currently disabled).

Filter and Refresh#
VSS Reference User Interface - Alerts Tab - Manage Alerts Filters

The filter bar provides text-based filtering for the rules table:

  • Live Stream URL — Filter rules by stream URL (substring, case-insensitive)

  • Alert Type — Filter rules by alert type (substring, case-insensitive)

  • Refresh — Click to reload the rules list from the API

Alert Rules Table#
VSS Reference User Interface - Alerts Tab - Manage Alerts Table

The table displays all configured real-time alert rules with the following columns:

Column

Description

Actions

Duplicate (copy as new draft) and Delete (two-step confirmation: trash icon → confirm/cancel) for saved rules. For draft rows: Duplicate and Discard.

Thumbnail

Live stream preview image from the configured sensor. Automatically resolves the sensor from the stream URL.

Live Stream URL

For saved rules: read-only RTSP stream URL resolved at creation time. For draft rows: a sensor picker (combobox) sourced from VIOS’s live-stream catalog — the selected sensor’s RTSP URL is shown below the picker for verification.

Alert Type

Classification type for the alert rule. Editable for draft rows, read-only for saved rules.

Prompt

Detection prompt describing what the rule should look for. Editable for draft rows, read-only for saved rules.

Status

Rule status badge (e.g., “active”) with creation timestamp for saved rules.

Sorting: Saved rules can be sorted by Alert Type, Prompt, or Status columns using the three-state sort cycle (ascending → descending → reset).

Creating Alert Rules#
VSS Reference User Interface - Alerts Tab - Create Alert Rule with Sensor Picker

There are two ways to create a new alert rule:

  1. Sidebar button — Click “Create alert rule” in the left sidebar (visible when Manage Alerts tab is active)

  2. Inline button — Click “Create alert rule” at the bottom of the rules table

Both actions add a new draft row at the bottom of the table with editable fields:

  • Live Stream URL (required) — A sensor picker (combobox) populated from VIOS’s live-stream catalog. See Picking a sensor below.

  • Alert Type (required) — Specify the alert classification

  • Prompt (required) — Describe what the rule should detect

Click Save to submit the rule to the alert bridge API. The UI looks up the selected sensor name in the catalog, attaches the resolved RTSP URL, and posts the rule.

Picking a sensor

When you click “+ Create alert rule” (or duplicate an existing row), the UI immediately calls GET /v1/live/streams on VIOS to fetch the current catalog of registered live streams. Each catalog entry carries the friendly sensor name, its RTSP URL, and the VIOS stream id. The catalog is not cached — every “+ Create alert rule” click fetches it fresh, so sensors registered in VIOS (for example, after uploading a new video through NVStreamer or the VIOS UI) appear in the dropdown right away.

In the draft row’s Live Stream URL column:

  • Click the input to open a dropdown listing every sensor returned by VIOS.

  • Type to filter — the list narrows to entries whose name contains what you’ve typed (case-insensitive).

  • Click a suggestion, or use ↑/↓ and Enter to pick one. Escape closes the dropdown.

  • After selection, the chosen sensor’s RTSP URL is shown as a hint below the input so you can verify you picked the right one.

The dropdown shows friendly names (for example, warehouse-cam-1 or sample_warehouse.mp4), not URLs. You never need to copy/paste an RTSP URL — the UI resolves it from VIOS and sends it with the rule.

Custom sensor names

You can also type a sensor name that is not yet in the VIOS catalog (for example, a stream you plan to register later). The UI shows a “Not in VIOS catalog — will be created against this sensor name” hint below the input and forwards only the sensor name to the alert bridge; the alert bridge decides whether to accept the rule.

Empty state: When no rules exist, the table displays instructions to use the “Create alert rule” button to get started.

Deleting Alert Rules#

To delete a saved rule:

  1. Click the trash icon in the Actions column

  2. The icon changes to a confirm/cancel pair

  3. Click the checkmark to confirm deletion, or the X to cancel

Draft rows that have not been saved can be removed by clicking the Discard button.

2. Dashboard Tab#

This tab shows the Kibana dashboard for the blueprint that it is deployed on.

VSS Reference User Interface - Dashboard Tab

Note

Blueprint deployments typically include a pre-configured Kibana dashboard (as shown above).

Refer to the Kibana documentation for usage details.

3. Search Tab#

Confirmation state (shown for 2 seconds after clicking). The clip context has been attached to the chat input.

Disabled

The button is grayed out when the Chat Sidebar is not available (e.g., chat sidebar feature is not enabled in the deployment).

Note

The + Chat button adds the video clip as a context reference — it does not automatically send a message. After adding context, open the Chat Sidebar and type your question. Multiple clips can be added as context before sending a query.

Video Playback#
VSS Reference User Interface - Search Tab - Video Playback

Click the play button or thumbnail to open the video playback modal with:

  • Play/Pause controls

  • Seek bar

  • Volume control

  • Fullscreen option

  • Search by Image button (appears when video is paused, if enabled)

Requires: VST service connectivity and proper sensor configuration.

Chat Sidebar#

VSS Reference User Interface - Search Tab Overview with Open Chat Sidebar

The Search Tab includes the Global Chat Sidebar on the right side, providing direct access to the Vision Agent without leaving the search interface. Refer to the Global Chat Sidebar section for full feature details (video upload, chat controls, settings, etc.).

Toggle:

  • Click the vertical “Chat” tab on the right edge to open or close the sidebar

  • The sidebar is resizable by dragging its left edge (between 1/3 and 2/3 of the content area width)

  • Default width: 380px

Interaction Modes:

When the Chat Sidebar is open, the behavior is similar to when it is collapsed while an agent query is executing: the search controls (search input, source type, filters, and filter tags) are disabled in both cases. In the open state, users interact with the agent through the Chat Sidebar, and the agent’s responses can automatically populate the search results grid. This allows conversational search — ask the agent a question and see matching video results appear in the main search area.

Example

Type a natural-language query in the Chat Sidebar and the agent will run a search and fill the results grid. For example, ask “person with yellow hat carrying boxes”; the agent interprets the query, runs the search, and matching video clips appear in the main area. The screenshot below illustrates this flow: the query in the chat and the corresponding search results (e.g. thumbnails and clips) shown in the grid.

VSS Reference User Interface - Search Tab - Chat query "person with yellow hat carrying boxes" and search results

When the Chat Sidebar is collapsed, the search controls are re-enabled and users can perform manual searches with filters as usual.

Unseen response indicator:

When a response to a query is unseen and the Chat Sidebar was closed, the vertical “Chat” tab on the right edge shows an orange border once the new response is generated to indicate unseen content. You can clear the indicator (mark as seen) in either of these ways:

  • Open the Chat Sidebar — viewing the content marks it as seen and removes the orange border.

  • Click the cancel button on the orange border — marks the new content as seen and removes the indicator without opening the sidebar.

Agentic Query Results#

When a query is submitted through the Chat Sidebar, the agent’s response can populate video results directly in the Search Tab’s main content area. The agent interprets the natural language query, executes a search, and matching video clips appear in the results grid alongside the chat response.

At the bottom of the agent’s response in the Chat Sidebar, a “See all results in: Search Tab” link is displayed. When the user is on a different tab (e.g., Alerts, Video Management), clicking this link navigates back to the Search Tab and displays the query results.

VSS Reference User Interface - Search Tab - Back to Search Tab link in agent response

Critic Verification#

When the Critic Agent is enabled and has run for a search request, search result cards display verification details for each evaluated clip. The Critic Agent uses a VLM (Vision Language Model) to verify whether each search result actually matches the user’s query.

Users can toggle the critic agent on or off per query using the Enable Critic toggle in the Chat Sidebar settings.

VSS Reference User Interface - Search Tab - Enable Critic Toggle in Chat Sidebar Settings

When the critic agent has run, the search result cards show the verification outcome:

VSS Reference User Interface - Search Tab - Critic Verification on Video Cards

Result Card Indicators:

Each evaluated result card shows the critic verdict through visual cues:

Indicator

Description

Border color

The card border is colored to reflect the verdict: green for confirmed, red for rejected, yellow for unverified. Cards from searches that did not use the critic agent retain the default gray border.

Verdict badge

A colored badge below the similarity score displays the verdict: ✓ Confirmed (green), ✗ Rejected (red), or ? Unverified (yellow).

Criteria chips

Below the verdict badge, each criterion extracted from the query is listed as a small chip with a green check (✓) when satisfied or a red cross (✗) when not satisfied (e.g., subject:person, carrying boxes, wearing a yellow safety vest).

Sorting Behavior:

When critic results are present, search results are automatically re-sorted by verdict before similarity:

  1. Confirmed results appear first

  2. Unverified results appear second

  3. Rejected results appear last

Within each verdict group, results are ordered by descending similarity score. When the critic agent did not run for the request, results retain their original similarity ordering.

Note

The Critic Agent is enabled by default. To disable it across the entire deployment, set ENABLE_CRITIC=false before deploying. See Critic Agent Overview for more details.

Search by Image#

VSS Reference User Interface - Search Tab - Search by Image Button

Search by Image allows you to select a detected object from a paused video frame and perform an agentic search for visually similar objects across all cameras and video streams.

Note

Search by Image is only available when the mediaWithObjectsBbox option is enabled in the deployment configuration. This feature requires the MDX Web API (/frames endpoint) and VST Picture API to be deployed and accessible.

How to Use:

  1. Play a video — Click on a video card from the search results to open the video playback modal.

  2. Pause the video — Pause playback at the frame containing the object of interest. A “Search by Image” button appears in the center of the paused video.

  3. Enter Search by Image Mode — Click the “Search by Image” button. The system fetches the still frame and any detected bounding boxes from the backend.

  4. Select an object — Click on a bounding box to select the target object. The selected box is highlighted in green. An info bar below shows the selected object ID and type.

  5. Execute the search — Click the “Search” button in the info bar to find similar objects across all streams. The agent will process the query and return matching results.

  6. Cancel — Click “Cancel” in the info bar or close the modal to exit Search by Image mode.

VSS Reference User Interface - Search Tab - Search by Image Overlay with Bounding Boxes

Search by Image Overlay:

When Search by Image mode is active, the video is replaced by a still frame with bounding boxes drawn around detected objects:

Element

Description

Frame Image

The still frame captured at the paused timestamp, fetched from the VST /picture API

Bounding Boxes (white)

Detected objects in the frame. Hover to highlight; click to select

Selected Box (green)

The currently selected object for search. Click again to deselect

Info Bar

Displays the selected object ID, object type, and action buttons (Search / Cancel)

Info Bar States:

  • No objects detected — Displays “No bounding boxes detected in this frame”

  • Objects available, none selected — Displays “Select one to search for similar object embeddings across views/cameras”

  • Object selected — Displays the object ID and type (e.g., Person, Pallet) with a “Search” button

Search Execution:

When you click “Search” after selecting an object, the system:

  1. Sends a query to the Vision Agent: Find similar objects matching object_id=<selected_id>

  2. Closes the video modal

  3. Displays matching results in the search results grid, showing video clips where similar objects were detected across different cameras/streams

Tip

For best results, pause the video at a frame where the object of interest is clearly visible and the bounding box accurately covers the object.

4. Video Management Tab#

Video Management Tab provides an interface for managing video streams, including uploaded video files and live RTSP camera feeds.

VSS Reference User Interface - Video Management Tab Overview

Key Features:

  • Upload video files (MP4, MKV formats)

  • Optional upload configuration fields (if configured via system settings)

  • Add live RTSP camera streams

  • Grid view of all streams with thumbnails

  • Search and filter streams by name and type

  • Bulk selection and deletion of streams

  • Real-time upload progress tracking

  • Stream metadata display (codec, framerate)

Main Sections:

This guide covers the primary interface components:

  1. Toolbar - Search, filter, upload, and bulk operations

  2. Streams Grid - Visual display of all video and RTSP streams

Both toggles are enabled by default. Disable either to filter the view.

Upload Video / Add RTSP Buttons#
VSS Reference User Interface - Video Management Tab - Upload Video and Add RTSP Buttons

  • Upload Video - Opens the video upload dialog for uploading video files

  • Add RTSP - Opens the RTSP stream configuration dialog for adding live camera feeds

Note

These buttons may appear disabled (grayed out) if the deployment does not support the respective features. A disabled Upload Video button indicates that video file uploads are not enabled in the current deployment configuration. Similarly, a disabled Add RTSP button indicates that RTSP stream management is not supported in this deployment.

Streams Grid#

VSS Reference User Interface - Video Management Tab - Streams Grid

The main content area displays all streams as cards in a responsive grid layout.

Stream Card#
VSS Reference User Interface - Video Management Tab - Stream Card

Each stream card displays:

Element

Description

Checkbox

Select stream for bulk operations

Stream Name

Sensor or file name (displayed in header)

Thumbnail

Live preview for RTSP, last frame for uploaded videos

Type Badge

“RTSP” for live streams, file extension (e.g., “MP4”, “MKV”) for videos

Copy Button

Copy stream context to clipboard as JSON (contains sensorName and streamId)

Video Metadata

Video codec (e.g., H264, H265) and framerate (e.g., 30 fps)

Video Preview#
VSS Reference User Interface - Video Management Tab - Video Preview

When you click on a stream card, a popup opens to play the video preview for that stream.

Empty State#
VSS Reference User Interface - Video Management Tab - Empty State

When no streams exist, an empty state is displayed with a button to upload your first video. Files can also be dragged and dropped into the empty state to upload them.

Upload Dialog#

VSS Reference User Interface - Video Management Tab - Upload Dialog

The upload dialog allows you to select video files and optionally configure them before uploading:

File Selection:

  • Click the dashed area or drag-and-drop files to select videos

  • Supported formats: MP4, MKV

  • Multiple files can be selected at once

  • Click “+ Add More” to add additional files after initial selection

File Configuration:

Each file in the upload list can be expanded (click the chevron icon) to configure optional fields if system-level configuration is enabled.

Note: Configuration fields are optional and only appear if NEXT_PUBLIC_CHAT_UPLOAD_FILE_CONFIG_TEMPLATE_JSON is configured. Common field types include boolean toggles, text inputs, number inputs, and select dropdowns. The available fields depend entirely on your system’s deployment configuration.

File Management:

Each file in the list shows the video icon, filename, file size in MB, expand/collapse button (chevron icon) to show/hide configuration fields, and remove button (X icon) to remove file from upload queue.

Click “Upload (N)” button to start uploading all files, or “Cancel” to close the dialog without uploading.

Upload Progress Panel#

  • Close Panel - Dismiss the progress panel (only available when no uploads are in progress)

Note: The system uploads multiple files in parallel for faster processing. Successfully uploaded videos will appear in the streams grid automatically.

Adding RTSP Streams#

VSS Reference User Interface - Video Management Tab - RTSP Dialog

Click the “Add RTSP” button in the toolbar to add a live camera stream.

RTSP URL Field (Required):

Enter the RTSP stream URL in the format: rtsp://[username:password@]hostname:port/path

Examples:

  • rtsp://192.168.1.10:554/stream1

  • rtsp://cam-warehouse.example.com:554/warehouse/cam01

The system will automatically extract a suggested sensor name from the URL path.

Sensor Name Field (Optional):

Enter a friendly name for the sensor (e.g., “Warehouse Camera 01”).

  • Auto-populated from RTSP URL path if not manually specified

  • Can be manually edited to provide a more descriptive name

  • Used for display in the streams grid

RTSP Validation:

The system validates RTSP URLs:

  • Must start with rtsp://

  • Connection is verified when “Add RTSP” button is clicked

  • Error messages displayed if URL is invalid or connection fails

Click “Add RTSP” to add the stream or “Cancel” to close the dialog.

Deleting Streams#

VSS Reference User Interface - Video Management Tab - Stream Deletion

To delete streams:

  1. Click the checkbox on one or more stream cards to select them

  2. Click the “Delete Selected (N)” button in the toolbar

  3. The selected streams will be deleted and the streams grid will be refreshed.

Warning: This action cannot be undone. Make sure you want to delete the selected streams before confirming.

Known Issues#

Overall Issues#

No known issues.

Global Chat Sidebar#

  • If the backend agent restarts, the UI doesn’t clear the outdated chat history.

Alerts Tab#

  • When a sensor is removed, its existing alerts may still appear in the alerts list, but the related thumbnails and videos are no longer accessible because the sensor data has been deleted.

  • Real-time alert rules created from the Manage Alerts sub-tab generate no alerts due to a bug w.r.t the parameters sent with the create request. Workaround: create the alert via the chat window first, then UI-created rules for that sensor work.

Dashboard Tab#

No known issues.

Search Tab#

  • The “Show top K Results” value should be kept below 100 for optimal search performance. Setting a higher value may result in slow responses or no results being returned.

  • When a live RTSP stream is removed directly from NVStreamer, the VSS Search UI may still display the stream as active.

Video Management Tab#

  • There is no way to rename a stream after uploading. This will be fixed in an upcoming update. Until then, to use a different name you must upload a new stream with the desired name.

  • When using Select All delete to remove a mix of RTSP streams and uploaded videos, the RTSP stream entry may stay visible (stale) after the first delete. The UI list is not refreshed automatically; a second Select All delete (or a manual UI refresh) is required to fully clear the RTSP entry.
