Permanent Noise Monitoring: Nor1545B, NoiseCompass & NorCloud
Class 1 unattended environmental monitoring for months or years: the Nor1545B terminal, NoiseCompass direction of arrival, and the NorCloud platform — with options to integrate your own systems. For ports, airports, industrial sites, construction and city networks across Asia and the Middle East.
The system, in three parts
Nor1545B terminal
A permanent Class 1 monitoring terminal (Nor145-based): IP66/67 enclosure, −20 to 50 °C, 4G/LTE/WiFi/LAN, GPS, solar + battery (up to ~3 days autonomous), 24/7 audio, five triggers, plus IP camera and weather data.
NoiseCompass (Nor1297)
Determines the direction of arrival of noise at the terminal, separating the source from background and giving defensible directional evidence in complaint and compliance disputes.
NorCloud
Live dashboards, exceedance and system-health alerts, automatic Lden reporting, unlimited multi-site management, and AI source classification with NoiseTag.
The Nor1545B terminal
- Class 1 (IEC 61672) core, based on the Nor145 sound level meter
- IP66 enclosure (IP67 with extra sealant), −20 to 50 °C
- LAN / WiFi / 3G / 4G / LTE connectivity with built-in GPS
- Mains, 12 V or solar power; Tracer 22 Ah battery (up to ~3 days autonomous) on the Nor1545B
- 24/7 audio recording, local SD storage with cloud redundancy
- Five simultaneous triggers, email/SMS threshold alerts, event-triggered recording and photography
The NorCloud platform
- Live browser access with customizable dashboards
- Exceedance alerts plus system-health alerts (lost connection, mains failure, low battery, calibration errors)
- Integrated report designer and automatic Lden reporting (hourly to yearly)
- Manage unlimited projects and terminals from one interface
Integration & API
The system is built to fit into your existing infrastructure — from digital I/O to server-level data transfer:
- Two configurable digital inputs and one output on the Nor1545B for system integration
- Automatic data transfer to local servers in multiple data formats
- API and custom integrations (SCADA, city dashboards, third-party platforms) — available on request

Deployment scenarios
Ports & airports
Perimeter and community noise, with aircraft/vessel classification via NoiseTag and direction via NoiseCompass.
Industrial & utilities
Fence-line compliance for substations and plants — unattended long-term monitoring with instant alerts.
Construction & quarries
Permit-duration and blasting-adjacent monitoring, with event-triggered recording as evidence.
Smart city & government
City-wide networks, regulatory dashboards and multi-site reporting for authorities.
Why permanent monitoring?
Handheld surveys capture only a snapshot. Permanent monitoring with the Nor1545B gives continuous 24/7 coverage for months or years — the basis for long-term compliance, complaint resolution and environmental impact studies, with instant alerts on exceedance and legally defensible data stored both locally and in the cloud.
Frequently asked questions
What's the difference between the Nor1545 and Nor1545B?
The Nor1545B adds multiple power sources (a Tracer battery giving up to ~3 days, solar and mains) and two digital inputs plus one output for system integration. The standard Nor1545 runs from mains.
Is the system Class 1?
Yes. The terminal is based on the Class 1 Nor145 sound level meter (IEC 61672), for legally defensible data.
Can it run without mains power?
Yes — the Nor1545B combines solar and a Tracer battery for up to ~3 days of autonomous operation, with automatic charging from mains when available.
Does NorCloud offer an API to integrate with our own systems?
Data can be transferred automatically to local servers in multiple formats, and the Nor1545B provides digital I/O for integration. An API and custom integrations are available on request — talk to our engineers.
