how to complement image information

Sounds can clearly identify hazardous events, even in noisy background:

  • Impulsive sounds: gunshot, explosion, car crash, glass shattering, etc.
  • Continuous sounds: structural collapse, human scream, brawl, etc.

Recognition of sound outstandingly helps:

  • Threat alert
  • Early warning on threats
  • Potential risks
  • Acts of vandalism
  • Suspicious or forbidden behaviour

Location and nature of hazard can trigger:

  • Pointing and tracking cameras
  • Warnings or deterrent actions
  • Police intervention
