Canterbury Seismic Instruments (CSI) currently produces three product ranges;
The CUSP-3 series, a 3 to 9 channel data accelerograph range
for strong motion seismic and structural health monitoring,
The CUSP-M, a multichannel central data logger with
remote sensors for structure or down-hole arrays.
The CUSP-HUB, a complete network management system, even providing
a website for data dissemination and the capability to convert a network of the CUSP-3 series instruments
into an advanced array.

The CUSP-3 series range offers advanced features at a low cost.
Common to all the products in the CUSP range is GPS timing,
full Internet connectivity including Ethernet, modem access,
cellular access etc. The communications utilises standard
web browser interfaces, including PPP dial in and out.
Security is provided by 128bit SSL data encryption. The
standard sensors utilise MEMs accelerometers.
High quality signal processing ensures excellent gain and phase linearity
and axial alignment.

The CUSP-M instrument is a multichannel (32x triaxial sensors) seismic data acquisition
system designed for structural, building and dense array use (free-field and down-hole).
The CUSP-M provides fully UTC synchronised timing, utilising the best Trimble timing-specific
GPS recievers to discipline a temperature compensated internal timing system. This provides
maximum timing accuracy, even during periods without GPS reception.
The CUSP-M also offers the ability to connect
the sensors and the GPS receiver to the central control unit using a buildings
existing ethernet wiring, greatly reducing costs and
time for installation.

The CUSP-HUB is an advanced network managment system, allowing clients
to easily create and manage large networks of CUSP-3 series instruments.
The HUB provides an easily configurable central repository for records,
with provision for allowing data access via a built-in webserver. The HUB also
allows the conversion of a network of CUSP-3 series instruments into an array.
This operates by receiving real-time triggering data from the network and issuing
a global trigger event whenever any of several pre-selected triggering sequences occurs.
This feature greatly enhances the capabilities of a strong motion network, ensuring
all instruments within the network record all events, regardless of local noise levels.
The other features you'd expect from a network management solution are
provided, including daily status reports, realtime event reports, diagnostics alerts etc
via email, presettable contraints on all diagnostics parameters etc.
The HUB can also function with redundency, both for data storage via network data mirroring
and in its operation by using mulitple HUB units in parallel.
