Semantic AI search

The BLAZE Appliance provides semantic search functionality. This feature allows you to quickly find desired video events using natural language without knowing specific search conditions or timestamps.
Note: Semantic search is supported only on specific models of the BLAZE Appliance.
Note: Semantic search settings and banned term settings can be viewed and modified in Settings > Servers > Semantic AI.

To search for object events using semantic search

  1. On the Home page, click Objects.
  2. Click Semantic search.
  3. Select filters before performing the search.
    • Time: Click the Time filter to open the date selection panel. Set the start and end date and time range for the event search, and then click .
      • Select Any time to search across the entire video storage period on the server.
      • You can also select a predefined range based on the current time, such as Last 1 hour, 12h, 24h, or 7d.
    • Devices: Click the Devices filter to open the list of devices that support semantic search. Select the device to search and click Select.
      • Click All devices to select all cameras or devices configured for semantic search.
      • Because object event conditions can be detected only on AI-enabled devices, devices that are not configured for semantic search do not appear in the list. To display them, click and select Show devices without analytics. Devices that do not support semantic search are listed under Devices without analytics.
    • Confidence level: Adjust the confidence level to fine-tune search accuracy.
  4. Enter a search query.
    • Describe the situation you want to find using natural language. (e.g., Find the person in a red jacket sitting on a chair)
      Note: Input must be in English.
    • If the query contains banned terms, the search will be blocked. Banned terms include the following (users can configure banned terms in Semantic AI):
      • Explicit sexual content or provocative language
      • Defamatory or demeaning statements about individuals
      • Dehumanizing comparisons of people to animals
      • Subjective evaluations of personal traits such as appearance, wealth, or social status
      • Statements that infer or speculate about individuals based on their appearance
      • Disclosure of private information related to education or religious beliefs
      • Use of real names of specific individuals, including public figures
      • Disclosure of information related to race, ethnicity, or nationality
      • Content that promotes or glorifies self-harm or suicidal behavior
      • Descriptions or incitement of physical harm or violent acts
  5. Semantic search results are displayed in the panel.
  6. Adjust the confidence level in 5 steps from the left panel.
    • The default value is Medium. Adjust the confidence level to fine-tune search accuracy.
  7. Click an item in the results panel to open the Event Details panel.
    • View detailed event information and play the video. You can also add bookmarks or export the video as a file.
