The LiveNoise LNT-SE noise monitor mounts on a wall and just needs power (adapter included) and access to a WiFi or Ethernet wired network. It communicates to our cloud server or to the LiveNoise Supervisor software to provide a real-time display of noise levels and long term noise reports.

Internal Network and/or Cloud Based

LiveNoise System - "Internal"

On a purely "internal" system, the noise monitor communicates continuously with the LiveNoise Supervisor software running on a computer on your network to provide real-time noise levels, long-term stored noise measurements and high-noise alarms. Using this setup there is no need for the monitors or software to communicate with the outside world.

The LiveNoise Reporter software can generate reports of the noise and alarms over daily, weekly, monthly or other custom periods.

LiveNoise System - "Cloud"

With the cloud based reporting system the noise monitor uploads its measurements to our LiveNoise Server for you to view using the Web Reporter. You access this through a web browser.

With this setup there is no software to run locally and you can view the results from anywhere with Internet access.

Best of Both Worlds

The standard LiveNoise System includes both methods. You can use the Supervisor software on your local network, you can use the cloud based reporting, or you can use both at the same time.


The LNT-SE noise monitor mounts with four screws that are accessible from the front of the case with the font panel removed.

wall mounting the noise monitor

The type of fixing to use depends on what the monitor is being mounted to - screws for wood, plugs and screws for brick.

The noise monitor is lightweight and so does not need a strong structural mount.


The noise monitor comes with a 10 m (32 ft) power cable fitted through a weatherproof gland. This cable can be removed and shortened if necessary. A 24VDC power adapter is included with each noise monitor. The extension cable connects to the power adapter, which must be mounted indoors or in its own weatherproof enclosure.

Typical Installation

Typical Installation - Noise Monitor Mounted to an Outside Wall


The LNT-SE noise monitor needs to communicate with the LiveNoise Supervisor software to provide a real-time display of sound levels and for long-term noise measurement storage. With the Supervisor software running on a computer on your network, the LNT-SE noise monitor just needs WiFi access or a wired Ethernet connection to the same network.


If you have a WiFi network then all you need to do is provide the noise monitor with the router name and password. This configuration is carried out using the supplied software.

Wired Ethernet

The noise monitor has an Ethernet port (RJ45) for connection to your wired network. This is a weatherproof socket and for outdoor use you will need a suitable weatherproof cable or weatherproof RJ45 cable housing. For indoor use a standard RJ45 network cable can be used.

LiveNoise Network

The LNT-SE will need to be connected to your network in order to send the noise measurements to the Supervisor software or to the cloud server, depending on your configuration.

Local Network

A computer on the network runs the LiveNoise Supervisor software, which shows the real-time noise levels and downloads all the measurements for long term storage and reporting.

Other computers on the network can access the noise measurements using the LiveNoise Reporter software.

Cloud Reporting

The monitors send the noise measurements to our server and you view them using Web Reporter.


The LiveNoise Supervisor, Reporter and the online Web Reporter are included when you buy one or more LiveNoise Noise Monitors.

With the noise monitors connected to your network, you can choose how you want to deal with a live display and with long term reporting.

Local Network

Operating on your own WiFi/Ethernet network, with live sound levels sent to a Windows computer, you will use the following software:

Supervisor - Connects to all your noise monitors, showing the live sound levels, indicating any high noise level alarms and storing long term measurements.

Reporter - Using the measurements stored by Supervisor, this software generates long term noise reports: daily, weekly, monthly or custom periods.

Online Reporting

The noise monitors send all the noise measurements to our cloud server, from where the Web Reporter provides you with noise reports.
