What is an Online Acoustic Camera?
An online acoustic camera (or fixed acoustic camera) is a permanent installation device located at critical points. Its functions are:
Detection partial discharge (partial discharge)
Gas leak identification
Detection of abnormal sound patterns
Its advantages: intelligent on-device analytics, and easy integration into large systems via API—ideal for robots, 'robot dogs', inspection lines, or industrial monitoring systems.
Why Should You Choose This Product?
Preventive, not reactive — minor damage is detected long before major losses occur
Efficient & automatic — no need for a special operator to monitor the sound
Scalable & flexible — from small modules to PTZ systems
Smart investment — maintenance costs can be much lower than major damage.
Featured Features
Here are some of the superior features it has:
| Feature | Real Benefits |
|---|---|
| Onboard AI + Signal Analysis | Not just recording sound — this camera is capable of automatic failure classification (discharge, leakage). |
| Extremely resistant housing (IP68 / ATEX) | Safe to install in outdoor areas and danger zones. |
| API / network integration | Data and alarms can be directly sent to a central platform or robotic system. |
| Modular & Various Models | There are lightweight USB module variants, extreme condition fixed cameras, and PTZ systems for wide areas. |
| Low Power Consumption | Ideal for long-term use without the need for frequent maintenance. |
Real Application / Case Study
Apply this camera in:
PLN & electricity facilities — detects premature discharge in insulators and high voltage components
Gas pipelines and refineries — find small gas leaks before they become a disaster
Oil & gas industrial infrastructure & facilities
Robotic system / inspection drone — this camera can be installed as a “smart ear” for inspection robots/drones
Imagine a robot dog walking in a pipe area and an acoustic camera always detects “abnormal sounds” — you can get real-time alerts to act quickly.
