Seismic monitoring systems play a crucial role in enhancing our understanding of building behavior and improving design codes. Many municipalities, such as the City of Los Angeles, CA, USA, require seismic instrumentation or offer incentives like reduced inspection time as part of building occupancy resumption programs, like BORP in San Francisco, CA, USA.
For instance, as per the 2008 Los Angeles Building Code (§1613.8.2), buildings with over ten stories or six stories with an aggregate floor area of 60,000 square feet or more must have a minimum of three accelerographs deployed at the base, middle, and top of the structure. These three instruments are typically placed in a vertical stack and interconnected to facilitate common triggering and timing.
SENTINEL-M is an internet-ready, code-compliant building instrumentation system designed for seismic monitoring, meeting the necessary requirements for reliable and accurate data collection. Embrace the future of seismic monitoring with SENTINEL-M and stay at the forefront of seismic technology, empowering you with the insights needed to build with unmatched confidence and resilience.

The analog channels meet the electrical MEMS specifications and are synchronously sampled up to 500 samples/second at a resolution of 24bit with a dynamic range that exceeds 120dB@100Hz. The integrated memory bank (32 - 256 GB) allows you to manage a ring-buffer for long continuous recordings as well as event data.
The data format is MiniSEED.
The connection to the instrument can be local via network (LAN or WiFi) or, alternatively, remote using the internal 4G CAT1 modem (optional).
The instrument can be used as a stand-alone unit, or it can be used in a MASTER-SLAVE based monitoring network where multiple instruments are connected to each other; Sentinel-M is compatible with both the Triton and Atlas and this can be useful when superior dynamics are needed, for example, as a near field unit.
Thanks to SeedLink protocol SENTINEL-M is compatible with most popular seismic analysis software (Seiscomp, Antelope, and Earthworm).
Sentinel-M is powered by an external DC source (5 - 16 Volt DC) and it is equipped with its own internal battery (LiPo) which can guarantee an autonomy of 5 hours in case of a blackout. The battery is a standard 18650 and can easily be replaced. The internal 4G modem (optional) is backed up by the internal battery.
Sentinel-M comes in an anodized aluminum case which is rugged and shock-resistant and thus suitable for field applications. Sensor connectors are industry standard M8, robust easy to find on the market.
