Go beyond environmental noise monitoring with Quantum Outdoor and MyCirrus
Quantum Outdoor is a powerful noise monitor with integrated cloud connectivity, perfect for unattended long-term environmental noise monitoring applications. It goes beyond regular long-term noise monitoring by offering all the freedom and benefits of remote 24/7 monitoring with the ability to see both live and historic noise level data on the MyCirrus cloud platform anytime, anywhere, using the Quantum portal. You can also set up comprehensive event-based triggers to record audio, and send alerts and notifications to users. This will allow users to react to and control noise events in real time.
Quantum Outdoor is available with flexible subscription plans to the MyCirrus cloud platform, allowing you to enhance the amount of storage and functionality of your Quantum network. Each Quantum Outdoor unit is supplied with a wall mounting kit and each network comes with one year’s subscription to the Standard Level MyCirrus cloud package.
Think outside the box and take your environmental noise monitoring to the next level
Each Quantum Outdoor unit communicates with MyCirrus, streaming data to it every second. This data is displayed in the live feed in the Quantum portal, allowing you to view it around the clock remotely from any device, anywhere in the world.
When your set measurement time is complete, you can view your time history noise data, which is stored on MyCirrus, along with any weather and audio data recorded during the measurement period.
You can create numerous audio triggers and notifications based on your own set of conditions for acceptable noise emissions. Automated email, SMS and push notifications through our dedicated smartphone application, allow noise issues to be controlled before a non-compliance condition arises.
Quantum Outdoor captures both 1:1 and 1:3 octave band data and stores it alongside all other measurement information in the Quantum portal, allowing you to further analyse your noise data to better understand the exact nature of the noise and its potential implications.
Use the frequency analysis screen on the Quantum portal to view your noise measurement's frequency data in exquisite detail. Explore each peak and trough in a fully navigable 3D model.
You can create detailed reports directly from the Quantum portal, based on the data captured by your Quantum Outdoor units. Several standard reports are available from the Quantum Portal and further user-definable options are planned for a future release. You can also export your data to our incredibly powerful licence-free reporting software, NoiseTools, for further in-depth analysis of your noise data.
Quantum Outdoor is weatherproof to IP65 standards, making it the perfect solution for any outdoor noise monitoring application. Furthermore, by adding our weather monitoring station to your Quantum Outdoor units, you'll get comprehensive data on rainfall, wind speed and direction, humidity, pressure and temperature sent directly to the Quantum portal.
