It is built around the removable SVAN 979 sound level meter housed in an IP65-rated, weatherproof enclosure with military-grade connectors. The station supports 4G connectivity with SIM card compatibility for real-time remote data access via the SvanNET platform, and can operate for approximately 4 days on its internal 17 Ah battery with optional solar panel support. Three parallel acoustic profiles with independent settings allow flexible measurement configurations, while a 16 GB microSD card provides onboard time-history logging.
