Electrical stress & gas trends
Partial discharge, transformer gas and moisture changes, and localized thermal anomalies.
Industry / Critical Infrastructure
Keep critical systems visible from equipment rooms to long, remote routes.
HERTZINNO combines acoustic imaging, online DGA, acoustic fingerprint monitoring, DTS/DAS and ground-vibration sensing across data centers, railway power assets, tunnels, cable routes, mines and protected perimeters.
Industry hub for facility, infrastructure, railway, tunnel, mining and operations teams.
A multi-layer infrastructure view
Critical infrastructure risks rarely stay inside one equipment category.
A data center depends on power rooms, cooling equipment and cable routes. A railway combines traction power, trackside assets and depot machines. Tunnels and mines extend risk across long routes and remote boundaries. The monitoring design should follow the physical signal, the asset distribution and the operating response.
This page organizes HERTZINNO capabilities by infrastructure environment. Detailed specifications and project-specific performance remain on the relevant solution and product pages.
Machine & cooling sound
Persistent acoustic changes from pumps, fans, chillers, compressors and depot equipment.
Distributed heat & vibration
Route-level temperature, disturbance and vibration events along cables, tunnels and fibers.
Ground activity & evidence
Excavation, vehicles, personnel and boundary activity at remote or protected locations.
01 / Facilities
Data Centers
Watch the infrastructure behind uptime, not only the server rack.
Data-center reliability depends on transformers, switchgear, UPS rooms, cooling plants, cable corridors and liquid systems operating together. Different sensing layers can reveal gas trends, discharge, abnormal machine sound and route-level temperature before a problem becomes obvious.
Typical monitoring priorities- Transformer rooms and critical power assets
- Switchgear, UPS rooms and busways
- Chillers, pumps, fans and compressors
- Cable, trench and liquid-cooling routes
02 / Mobility
Railway & Rail Transit
Combine traction-power inspection with route and depot condition monitoring.
Railway infrastructure combines high-voltage electrical assets, cable systems, trackside equipment and mechanical or pneumatic systems. Portable acoustic inspection can support source localization, while fixed and distributed sensing can cover selected substations, routes and restricted locations.
Typical monitoring priorities- Traction substations and switchgear
- Cable terminations and overhead accessories
- Trackside power and signaling assets
- Depot motors, fans, pumps and air systems
03 / Routes
Tunnels & Cable Routes
Extend temperature and disturbance visibility along the route, not only at point sensors.
Cable tunnels, utility corridors and transport infrastructure can extend for kilometers. DTS provides distributed temperature visibility for hotspots and fire-risk monitoring, while DAS can localize vibration, intrusion or disturbance events along a sensing fiber. The two technologies should be selected for different physical signals.
Typical monitoring priorities- Power cables, trays and technical corridors
- Tunnel temperature and fire-risk monitoring
- Route vibration and external disturbance
- Restricted-access and underground assets
04 / Remote Assets
Mining & Perimeter Assets
Turn remote ground activity into classified, located and reviewable events.
Mine boundaries, protected resource areas and remote corridors may lack utility power, permanent personnel and complete incident evidence. Ground-vibration nodes can classify selected excavation, vehicle or personnel events and add location and imagery, while DAS can extend route-level vibration monitoring along existing fiber.
Typical monitoring priorities- Excavation and heavy-vehicle activity
- Mine-boundary and protected-zone events
- Remote visual verification and location
- Route-level vibration and intrusion sensing
Risk-to-method map
Match each infrastructure risk to the signal that can reveal it.
A critical-infrastructure programme does not need one sensor everywhere. It needs a clear relationship between the asset, the early signal, the coverage distance and the operating response.

Monitoring architecture
Build the sensing layer around asset density, route length and response time.
Portable inspection, fixed equipment monitoring, online transformer diagnostics, distributed fiber sensing and autonomous ground nodes serve different operating objectives. They can share a platform strategy without being presented as interchangeable technologies.
Portable inspection
Use acoustic or acoustic-and-thermal cameras for electrical assets, machinery, air systems and targeted field checks.
Fixed acoustic monitoring
Continuously observe selected electrical rooms, substations, machinery zones and restricted locations.
Online DGA
Track gas and moisture trends in transformers supporting critical loads and infrastructure.
DTS & DAS routes
