For cities
Smart city noise monitoring
Officials see where and when noise happens, block by block.
Sensors on existing poles log the type, level, location, and time of each noise event.

Solutions
One sound technology, three uses
We set up the same acoustic technology for city noise, industrial safety, and equipment inspection.
At a glance
Three ways we use sound
Each sensor analyzes sound on the device. Only the analysis results and the audio from each event are sent out. Pick a use to read the details below.
For industry
Industrial safety sound detection
Spots incidents outside the camera's view.
Sensors find where an abnormal sound came from and turn the nearest CCTV toward it.

For inspection
Handheld ultrasonic camera
Inspectors can pinpoint a fault on screen.
Overlays the spots where ultrasound comes from on the live camera image.

Smart city noise monitoring
Officials see where and when noise happens, block by block.
We place sensors where noise complaints keep coming back. Each one logs what made the noise, where it came from, and when. Officials can then choose enforcement hours and places, and decide where to add noise barriers or other facilities, without sending a crew to every complaint.
| Sounds we detect | Motorcycle noise, construction noise, car horns, and everyday noise in complaint areas |
|---|---|
| Where it is installed | Existing poles, such as CCTV poles and vehicle-detection poles. No new site is needed. |
| What the control screen shows | Live monitoring, a record of noise by site and hour, and reports on complaint responses |
In the Siheung pilot, complaints in the installed area fell about 60% between Dec 2025 and Jun 2026, with guidance only and no enforcement. Read the Siheung case →
- RESIDENTS
See your street
See how often noise happens on your street at night, and how that compares with other areas.
- LOCAL GOVERNMENT
Decide from records
Choose enforcement hours and places, and where to add facilities, based on records.
- POLICY MAKERS
Check whether a policy works
Turn the records into everyday noise indicators, and check whether a policy is working.
The control screen above shows sample data.
02 · Industrial safety
Industrial safety sound detection
Spots incidents outside the camera's view.
A camera sees only what its lens points at. Our sensors listen across a wider area. When they hear an accident sound or an equipment fault, they find where it came from and turn the nearest camera toward it.
Korea's Serious Accidents Punishment Act now covers workplaces with fewer than 50 employees. That makes it more important to catch an incident early and keep a record of how it was handled.
What happens when a sensor hears an abnormal sound
- 01
Abnormal sound
An accident sound or an equipment fault starts somewhere on site.
- 02
Detect and locate
The sensor identifies the sound and works out where it came from.
- 03
CCTV link
The nearest camera turns to that spot.
- 04
Control room alert
The control room receives an alert with video, and the event is saved to the log.
03 · Inspection
Handheld ultrasonic camera
Inspectors can pinpoint a fault on screen.
When a sensor flags a sign of trouble, an inspector takes this camera to the site. It overlays the spots where ultrasound comes from on the image of the equipment, so the fault is easy to find.
