Introduction

The Accuware Sentinel dashboard can be used at present to:

  • count the amount of the individuals detected, over time, by each one of the cameras.
  • searches for specific individual.

PLEASE READ: the Accuware Sentinel dashboard is under development and may be subject to changes and interruptions due to system maintenance and upgrades.

1 – Density Maps

Data are displayed inside a big table where each row correspond to an hour of the day and each column correspond to a time-window of 5 minutes. The Accuware Sentinel dashboard provides also an easy way to access to other important information about your installation.

Access the Accuware dashboard using the link provided by the Accuware technical support.

The top bar of the dashboard contains two filters that can be used to visualize data for a specific date and for a specific camera.

1.1 – Video Preview

In the top left corner of the dashboard it is possible find a widget that allows to visualize the processed video related to a chosen 5 minutes time-window. The 5 minutes time window can be chosen by clicking on one of the cells of the Time table). For each individual shown inside the processed video it is possible to see:

  • a number on top of each individual. This is the ID assigned to each individual by the Accuware Sentinel algorithm.
  • a box that represents the spatial occupancy of each indvidual.

1.2 – Time table

In the central part of the dashboard it is possible find a widget with a heat map. A heat map is a graphical representation of data where values in a matrix are represented as colors. A simple heat map provides a compact, visual summary of quantitative information. Some elaborate heat maps enable viewers to visualize complex data sets.

Inside each cell of the table it is possible to visualize the number of different individuals detected during a specific 5 minutes time-window of the day. The gradient of the cells varies according to the number of different individuals detected. Please note that:

  • Blank cells (no data) are shown when the video stream is not available for a specific time-window.
  • Data is updated every 5 minutes and there is approximately a 10 minute delay. So for example at 12.30 PM, the table will show data collected until 12.20 PM.

1.3 – Download/Events

In the top right corner of the dashboard it is possible find a set of tools:

  • CSV file: this button allows to download the CSV files that can be used to integrate the information produced by Sentinel inside your application. Everything about th CSV files is explained inside this support page.
  • Search Tracklets: by clicking on this link it is possible to access a tool that can be used to search for specific individuals (from now on: tracklets) detected across multiple cameras during a specific time-window (from now on: event).

2 – Search

This page allows to:

  • visualize all the individuals (from now on: tracklet) detected during the 5 minutes time-window (from now on: event) selected by clicking inside the density map.
  • perform different types of searches.

The page is composed of several widgets described in the followin paragraphs.

2.1 – Event XXX – YYY frames – ZZ minutes

This widget shows the processed video related to a the chosen 5-minutes time window (it is the same widget available in the density map page). For each tracklet it is possible to see:

  • a number representing the unique ID assigned to the tracklet.
  • a box that represents the spatial occupancy of that tracklet.

By clicking on the gear in the top-right corner of the widget it is possible to choose to visualize the original video.

Event XXX - YYY frames - ZZ minutes

2.2 – Tracklets for event XXX

This widget shows, for each one of the tracklet detected the first 10 images and the tracklet ID.  By clicking on one of the images:

  • the processed video will jump to corresponding frame.
  • the image selected will show up in the search widget in the right side of the page.

For each tracklet it is possible to show all the images by clicking on the cloud button available at the end of each row.

Tracklets for event XXX

2.3 – Search

This widget allow to perform different types of searches listed in the following paragraphs.

2.3.1 – Search for a specific individual

Search and visualize all the frames in which a chosen tracklets has been detected. All what needs to be done is to:

  1. click on the tracklet of interest among all the tracklets listed inside the widget “Tracklets for event XXXX”.
  2. click on the Search button available in the Search widget.

After clicking on the search button, the page will scroll down and the search results will be displayed after few seconds in a new widget called Search Results. The result section shows matches similar to the one you selected. The results are ordered by relevance and for each tracklet it is possible to see:

  • the Rank number in the search.
  • the Event in which the tracklet has been detected.
  • the camera in which the tracklet has been detected.
  • the Timestamp of the detection.
  • a temporal indication of when the tracklet has been detected (e.g. SAME TIME, 2 HOURS AFTER, AN HOUR BEFORE etc..)
  • the first 10 images of the tracklet.

By clicking on the gear button available in the top-right corner of the widget is it possible to:

  • Search range [hours]: limit the search to a specific time-window.
  • Restrict search area: limit the search to a specific area. Once this option is enabled it becomes possible to modify the search area (the geo-fence) directly on the video by changing the shape of the RED polygon overlying the video. By searching for a specific tracklets it will be returned only the tracklets that walked inside the geofence.
  • Search Monitor: limit the search to specific cameras.

Please note that:

  • the first row with the Search Results contains the same tracklet that has been chosen to initiate the search.
  • at present the max number of results returned is 200 tracklets.
  • By clicking on any of the images of the tracklet in the Search Results you will be taken to the processed video containing it. Here you can watch the processed video, or select a new tracklet for the search and repeat the process all over.

2.3.2 – Search for all the individuals detected inside a specific area

Search and visualize all the tracklets that have been detected inside a specific area. All what needs to be done is to:

  1. clear the Search area by clicking on the Clear button.
  2. Enable the click on the Restrict search area option by clicking on the gear button.
  3. Modify the search (the geo-fence) directly on the video by changing the shape of the RED polygon overlying the video.
  4. Click on the Search button.

After clicking on the search button, the page will scroll down and the search results will be displayed after few seconds in a new widget called Search Results. The result section shows only the tracklets that walked inside the geofence. The results are ordered by Event number and by Time. For each tracklet it is possible to see:

  • the Rank number in the search.
  • the Event in which the tracklet has been detected.
  • the camera in which the tracklet has been detected.
  • the Timestamp of the detection.
  • a temporal indication of when the tracklet has been detected (e.g. SAME TIME, 2 HOURS AFTER, AN HOUR BEFORE etc..)
  • the first 10 images of the tracklet.

By clicking on the gear button available in the top-right corner of the widget is it possible to:

  • Search range [hours]: limit the search to a specific time-window.
  • Restrict search area: limit the search to a specific area. Once this option is enabled it becomes possible to modify the search area (the geo-fence) directly on the video by changing the shape of the RED polygon overlying the video.
  • Search Monitor: limit the search to specific cameras.

Please note that:

  • at present the max number of results returned is 200 tracklets.
  • By clicking on any of the images of the tracklet in the Search Results you will be taken to the processed video containing it. Here you can watch the processed video, or select a new tracklet for the search and repeat the process all over.
