Possibilities of Audio and Video Surveillance

How to Use Sound to Get Better Outcomes – presented by Victor Wainwright, Owner/CEO of Security 101 and Aaron Siegelman of Axis Communications.

There is an increasing need to automate more outcomes in security management. For instance, since the bail reform act, there has been a 19% increase in incidents in NYC in a one year time period. To be able to automate outcomes (defer, detect, defense), you need to be able to predict incidents with greater accuracy.

With advances in Internet of Things (IoT), there are more options for predicting outcomes and automating responses. Audio can play an important role in this for the following reasons:

  • Can’t shut it off (unless deaf)
  • Invokes a response -- can be key to handling a security related threat or incident
  • Changes environment
  • Psychology of noise and how people are affected (there is a whole science behind the psychological impacts of noise)


Ways to use audio for security include:

  • Defer actions through annoyance
  • Provide help on directional issues
  • Automated loitering time alerts
  • Automated alerts in obstruction cases
  • Deter crime and provide safeguarding


Businesses and institutions who have deployed sound as part of their security solutions have seen some great results … large reduction in vandalism / theft, reduction in shrinkage, reduction in fraud, and even and increase in sales.

Sounds simple, but requires a good system to make it work. Proper engineering is required and use of good quality sound. Signal processing capability and quality of speakers have big impact. In addition, it often needs to work in conjunction with other systems such as video surveillance / analytics. The analytics determine there is a possible issue (e.g. intruder) which triggers messages through the sound system that respond to and thwart the possible situation.
