A Complete Monitoring Solution

Detect, Evaluate and Report


The Event Monitoring System from Seismic Source provides a tool for managing a series of seismograph stations. These stations can be near or far, but their data is immediately accessible.
The Event Monitoring architecture provides:

Internet access for unattended monitoring of multiple arrays

Email alerts based on user-programmed thresholds and tolerances

Analysis and reports of events, individually and across time windows

Easy access to event information from anywhere


System Software


The Seismic Source Event Monitoring System is built using leading-edge software.
The Event Monitor Software package includes:

Multiple Account and Project Management

Remote Configuration and Control of Digitizers

Scheduled equipment testing

Real-time status updates

Evaluation of detected events

Automated data collection and archiving


System Hardware


The Seismic Source Event Monitoring System uses the most advanced
and precise seismograph hardware available.
This system includes:

High precision, field-proven nodal seismograph hardware

3, 4, 6, 12 or 24 channel digitizer options

Many optional features:


- Internal or external sensors


- Internal or external battery


- Removable UBS-compatible memory



Sigma 4+ Digitizing Node

Event Monitoring Components:


Digitizing Station

Sigma 4+ Digitizing Node connected to a cabled network connection.


Digitizing Station w/ Wi-Fi

Sigma 4+ Digitizing Node connected to a network with a Wi-Fi transceiver.




Digitizing Stations w/ Remote Access

Sigma 4+ Digitizing Node connected to the Internet with a Remove Access Box and either a Cellular Data Modem or Wi-Fi.




Client Station in Office

A computer running EM Client and connected to the Internet.



 Station w/ Alarm Equipment

A computer running EM Alarms, with a relay network and siren, connected to the Internet.





Back Office Server

A computer running EM Server or EM Local. This computer communicates with digitizers stations near and remote, and users both near and remote running EM Client. It receives data and status from RABbits and Sigmas, it relays that information to the uses, and EM Server will also archive data and trigger alarms if required.

  - Peak Amplitude Levels
  - RMS Amplitude Levels
  - 1/3 Octave RMS Vector Sum, etc.
Multiple Unit Events can create Network Triggers
Events can be triggered based on Vibration Criteria
  Data Archive
Data is archived to removable media in the field including:
  - Digitizer Status Log
  - Detected Event Reports
  - Recorded Seismic Data

Local Monitoring w/ Data Backup


Adding an Internet connection to this system enables Event Monitor Local to upload information and data to a remote computer running Event Monitor Server.

Local Monitoring w/ Event Alerts

Adding Event Monitor Alarm to this system, plus a physical light or siren, gives Event Monitor Local a physical means to alert the operator or their village.computer running Event Monitor Server.

Examples of EM Server Configurations

Back in the office, a computer server maintains the Event Monitoring network. The software running on this server uploads alerts and data from the field sites, tracks accounts and projects, and ensures the results are available from anywhere with Internet access.

  Accounts, Projects, Deployments
A server can have multiple accounts. Each account:
  - Is secure and isolated from all other accounts
  - Has its own set of users
  - Has its own set of units (digitizers & RABbits)
  - Has its own set of projects
An account can have many projects, both active and inactive. Each project:
  - Project settings
  - Email settings
  - Report settings
A project can have multiple units deployed in it
A unit can be actively deployed to a single project
  Client / Server Architecture
The RABbit acts as client uploading data, status, analysis and events to server and downloading new config files and software updates
User computer running EMC acts as client to configure and visualize data and reports
Server acts as server and stores all the unit status, analysis and optionally data. If data offloading and archiving is a primary concern, then hosting an in-house server is preferred
  Information Availability
Data is uploaded from seismograph to server via the RABbit All status, analysis and data are stored on the server, not on user’s computers
Once status, analysis and data are on the server, it is available to the EMC users

The EMC Server Suite is a series of programs that (1) receive status, analysis, and seismic data from the field, and (2) monitor user logins/logoffs and control access to the various accounts and projects.


Seismograph Options


The Seismic Cloud System utilizes instruments from the Seismic Source line of seismographs, so each system can be customized for any need or situation:

Sigma 3+: Three channels and field rugged

Sigma 4+: 3 or 4 channels with internal sensors and batteries

DAQ3-3: Three channels for permanent installation

DAQlink 4: 24 channels and high samples rates

DX-6: 1 to 6 channels with space for user options


All of these seismographs use any sensor, and can be configured with geophones, accelerometers or hydrophones
