The station integrates a class 1 sound level meter with 4G and GPS  modems. The waterproof housing of SV 307 can be removed to get an access to the user interface with a colour display and keypad. The SV307 noise monitoring station is equipped with a patented MEMS microphone with a life-time warranty.

The SV 307 is designed for permanent noise monitoring, it has been equipped with a patented double self-system check: an inbuilt reference sound source producing 100dB at 1 kHz plus real-time check based on reference microphone.

The SV 307 has an internal Li-Ion battery and interface for connecting solar panels. A waterproof mains adapter for charging the battery and powering the station is also included.

SvanNET cloud service monitors the wireless communication, powering and access to the SV 307 data. The scope of the basic SvanNET can be extended with multipoint project management that offers data storage in the cloud, data sharing, advanced alarming and reporting features. SvanNET is an on-line solution which means it doesn’t require software installation and is accessible through a web browser. The responsive design enables use of SvanNET on various devices such as smartphones or tablets.
