"Operator panel" section#

The “Operator panel” section displays face recognition events (Figure 7). The section displays the last 30 events within the settings of handling policy for processing incoming images of the video stream. Receiving and displaying events is performed with minimal delays in near real time.

Click the “Get events” switch (1) to show events received via the WebSocket protocol. Click on the "Filters" button (2) to filter events by parameters (for more details, see the "Filtering events" section).

The page shows the last event data (3). An event can be either a face detection or video analytics "People Count", "Fight", "Weapon" and "Fire" (Figure 8).

Section "Operator Panel", "Fire" video analytics event

Photo image from a video stream;
"Source"—the name of the event source that recorded the event;
“Place”—location of the event—house number, street, city, district, area;
For face detection events:
Top match is the reference photo image of the face. If no matches are found for a photo from an event, then the column with the top match for this event will remain empty.
Event type—"Detection" when a face is detected on the frame, and "Match" when a match is found for the detected face in the database.
The date and time the event was recorded;
Information from the database, linked to a person from the control list;
“Person ID”—the identifier of a person card from the control list. The value is displayed if such an ID is present;
“Lists”—the name of the lists (list) to which the person is attached;
Value of similarity of the identified face with the reference (in percentage terms and with the color coding of similarity thresholds*);
For video analytics events:
"Event type"—takes values of "People Count", "Fire", "Weapon", "Fight" depending on the type of video analytics;;
The date and time of the start and end of the event;
For a people counting event, user sees information about the number of people detected in the processed video segment;
For a fire detection event, user sees the probability of fire in the frame is displayed in percentage, as well as information about the fire class, such as "Black Smoke", "White Smoke", "Fire";
For a weapon detection event, user sees the probability of weapon in the frame in percentage;
For a fight detection event, user sees the probability of fight in the frame in percentage;

* The color coding of similarity thresholds is configured in the config.json configuration file (see Luna POINT. Administration Manual).:

similarity values below “low” will be marked in red;
similarity values between “low” and “medium” will be marked in yellow;
similarity values above “medium” will be marked in green.

When you click on a block with an event on the right, the event details open.

Event details in the operator panel#

Event details are divided into four blocks and contain information about the date and location of the event, a photo of a full frame of the event, a map and video stream of the event, a summary of the match, as well as information about last events with the person from the card (for face detection event).

In the figure, blocks of event details are highlighted with numbers 1-4 (Figure 9). Description of the blocks are presented in tables (Tables 2-5)

The number next to the icon shows the number of applied filters. A short description of the elements and parameters of the filter block on the “Operator panel” page is presented in the table (Table 6).
