For decades, the core of security systems has been visual—the ability to «see.» Hanwha Vision‘s advanced camera technology has long been at the forefront, detecting and recording threats with crystal-clear images. But what about the blind spots that cameras can’t cover? To address this, Hanwha Vision is pioneering a new paradigm. The security that «listens.»

Hanwha Vision‘s AI Audio Solution leverages deep learning-based sound classification to identify specific sounds like screams or breaking glass. It then uses a TDoA (Time Difference of Arrival) algorithm with multiple microphones to pinpoint the location of the sound source. This innovative technology acts as a powerful complement to traditional video surveillance, filling critical gaps in security coverage.

The true value of this solution is its ability to provide proactive threat detection. It captures subtle audio cues that might precede an incident, enabling users to respond before a situation escalates. For example, in an unmanned retail store after closing hours, the system can instantly detect the sound of breaking glass and identify its direction. This allows for a swift response, minimizing damage and risk.

Hanwha Vision’s AI Audio Solution excels in environments with ambient noise, such as schools, offices, and retail spaces. It can accurately detect urgent sounds like screams (over 70 dB) or glass breaking (over 80 dB), even when there’s background noise like a vacuum cleaner. Audio Beacon (SPS-A100M), in particular, is a game-changer for sensitive areas where cameras are not an option, such as locker rooms, changing rooms, and restrooms. It provides a robust security alternative that enhances safety without infringing on privacy.

By integrating audio, Hanwha Vision‘s solution elevates security from a purely visual experience to a comprehensive «see and hear» approach. The microphones embedded in the cameras classify sounds and detect their direction, adding a new dimension of information to video data. This allows users to review both video and audio for a clearer, more complete understanding of an event, providing a holistic view of any security threat.

Hanwha Vision has released a new white paper to help users understand and deploy this technology effectively. This resource offers in-depth technical knowledge and practical application insights, helping you build the most effective integrated security system without unnecessary trial and error.
