Public Spaces & Safety
Acoustic monitoring for publicly accessible spaces that cameras can’t cover
Shopping centres, transport hubs, hospitality venues, and leisure facilities face significant liability in areas where visual surveillance is legally or ethically prohibited. We deliver continuous acoustic monitoring and real-time incident alerting — fully compliant, zero voice recording.
Your highest risk spaces are the ones you cannot watch
Public venues operate under a clear duty of care to staff and customers. Yet a significant proportion of the spaces where incidents are most likely to occur — public toilets, changing rooms, back-of-house areas, and private facilities — cannot be monitored by camera.
Traditional alternatives — security patrols, basic panic buttons, decibel alarms — are reactive, expensive, and demonstrably insufficient in high-footfall environments.

The Monitoring Gap
Public venues operate under a clear duty of care to staff and customers. Yet a significant proportion of the spaces where incidents are most likely to occur — public toilets, changing rooms, back-of-house areas, and private facilities — cannot be monitored by camera.
The result is a measurable liability gap. Assaults go undetected until it is too late to intervene. Staff in isolated areas have no reliable means of raising an alert. Incidents in camera-free zones are difficult to evidence and harder to prevent.
Traditional alternatives — security patrols, basic panic buttons, decibel alarms — are reactive, expensive, and demonstrably insufficient in high-footfall environments.
Continuous acoustic monitoring across your venue. No cameras. No recordings. No compliance risk.
The Acoustic AI Solution
Our solution deploys acoustic sensors in the specific areas of your venue where visual surveillance is prohibited — public toilets, changing rooms, back-of-house corridors, and isolated staff areas. Deeply AI's edge-based classification platform analyses sound patterns in real time, detecting the acoustic signatures of distress, aggression, and physical incidents the moment they occur.
When an event is detected, your operations or security team receives an instant alert with event type and location — enabling immediate, targeted response.
All processing occurs on the device itself. No audio leaves the sensor. No recordings are made. No voice data is captured, stored, or accessible to any third party — meeting the privacy obligations of high-footfall public venues operating under UK GDPR and the Human Rights Act.
No data transmitted
All processing occurs on the device. No audio is sent to any server, cloud platform, or third party.
No individuals identified
The system classifies acoustic patterns — it cannot identify individuals by voice or any other means.
No recordings made
Raw audio is analysed and discarded instantly after classification. Nothing is stored at any point.
Multiple environments.
One proven solution.
-
Public toilets, car parks, service corridors, and staff-only areas. Detect distress calls, altercations, and anti-social behaviour in real time. Reduce incident response times and support duty of care obligations to customers and staff.
-
Stations, airports, bus terminals, and associated facilities. Continuous monitoring in public toilet facilities, waiting areas, and isolated passenger zones.
-
Gyms, sports centres, swimming pool changing rooms, and club facilities.
Acoustic monitoring in changing rooms and shower areas without any visual surveillance — meeting operator duty of care obligations while fully respecting user privacy.
-
Schools, colleges, and universities. Toilet facilities, corridors, and common areas where cameras are inappropriate. Real-time alerting supporting safeguarding obligations under Ofsted and DfE frameworks.
-
Council offices, libraries, court buildings, and civic facilities. Staff safety monitoring in isolated areas and public-facing spaces where duty of care obligations apply but visual surveillance is restricted.
What We Detect
Recognised Sound Events
Comprehensive acoustic recognition for high-footfall public environments.
Our system is trained to detect a wide range of acoustic events relevant to public venue security — from individual distress calls to large-scale incidents. The system operates effectively in noisy, unpredictable environments, filtering ambient sound to isolate genuine security events.
Active sound categories are fully configurable per deployment — enabling venue operators to focus monitoring on the event types most relevant to their specific environment and risk profile.

Noise Resistant Analysis
Built for real-world environments
Public venues present one of the most acoustically challenging monitoring environments — high footfall, ambient music, HVAC systems, and constant background noise make traditional sound-triggered systems unreliable.
Our system is powered by Deeply AI's proprietary acoustic foundation model — trained on years of real-world environmental data across operational deployments in urban public safety, transit infrastructure, and high-noise industrial environments.
The result is a system that consistently differentiates genuine security events from background noise — delivering accurate alerts without the false positives that cause security teams to disengage from monitoring systems over time.
99.87% detection accuracy — achieved in continuous 85dB+ industrial environments (Hyundai Motor Group deployment).
Deployed in the real world
Our technology has been deployed in live public environments — including Naejangsan National Park in South Korea, where acoustic sensors monitor public toilet facilities for distress signals. Visitors are informed that conversations are not recorded — only emergency acoustic signals are detected.

The Monitoring System
Operations & Management
Every deployment includes access to a web-based monitoring dashboard — giving your security operations centre or facilities management team a centralised view of acoustic activity across all monitored zones, across multiple sites if required.
Instant Multi-Channel Alerting
Real-time notifications via email, SMS, and webhooks — delivering alerts directly to security control rooms or individual responders.
Event Management
Search and filter detected events without accessing any audio recordings. Bookmark critical incidents and maintain a complete, searchable event history.
Remote Equipment Management
Monitor sensor status across all deployed units. Configure settings and perform remote restarts without requiring on-site engineer visits.
Configuration Management
Adjust sensitivity levels and active sound categories per zone to match your specific venue risk profile and operational requirements.
Real-Time Analysis & Configuration
Live acoustic analysis with instant event detection. Configure analysis cycles, sensitivity levels, and active sound categories per zone.
Statistical Reporting
View event data by day, time period, location, and event type. Identify high-risk zones and peak incident times for management and insurance reporting.
Privacy Protection
Built to operate in environments governed by strict privacy and public safety legislation.
Built to operate in the most compliance-sensitive environments.
No recordings are made. No voices are captured. No data is transmitted or stored.
Public venue operators face a dual obligation — maintaining safety for staff and customers while complying with UK GDPR, the Human Rights Act, and the legal prohibition on visual surveillance in private spaces.
Listen AI Safety's Privacy Protection Mode meets both obligations by design:
Edge AI architecture — all processing on-device, no audio transmitted
Sensitive personal data excluded from analysis at the point of capture
Raw audio immediately and automatically discarded after classification
No voice recordings created, stored, or accessible at any point
Full UK GDPR compliance and Human Rights Act alignment
ICO-aligned — no requirement to register acoustic monitoring under current UK guidance
