The use of audio analytics along with video can provide faster comprehension of what is happening during a security incident, better and faster decision making, reduced false alarms and the ability reexamine the scene both by viewing video and listening to what happened.
In many situations, a security team has difficulty interpreting the scene they are observing. Audio in many cases can help bridge that gap providing actionable metadata in both real-time and forensic analysis to better understand the observed scenarios. The current state and future prospects of these technologies will be discussed:
- Sound detection like gunshots, breaking glass, door slamming and more
- Keyword detection – to identify violent behavior
- Voice analysis – to identify people under duress like panic, crying, shouting
