Data Acquisition Systems
Built for compliance. Tailored for your team.
Alliance’s Data Acquisition Systems (DAS) give facilities across the U.S. the tools to collect, validate, and report emissions data continuously — and to stay ahead of federal, state, and local regulatory requirements without the administrative burden.

Reduce time spent managing data.
Centralize data collection, validation, review, and reporting in a single system. Automated calculations and data handling reduce manual effort, minimize errors, and keep your records consistent and ready for audits.
Built for your facility. Backed by decades of expertise.
Designed from decades of air emissions compliance experience, each system is configured to your equipment, processes, and reporting workflows, not a one-size-fits-all setup. Continuous updates keep your system aligned with evolving regulatory requirements.
24/7/365 Dedicated Expert Support
Get direct access to a U.S.-based team of 15+ DAS specialists, available 24/7/365 to support your system, troubleshoot issues, and help maintain reliable compliance operations.
Our DAS Products
StackVision™
The most widely used DAS in the U.S., trusted by more than 3,100 air emission sources. StackVision is user-configurable — not a black-box programmed solution — so your team can manage configurations, calculations, and alarms without writing a single line of code.
Prism
A scalable DAS solution purpose-built for facilities that need flexibility without complexity. Prism grows with your operation and integrates with the same 8864 Data Controller hardware platform.
Hardware That Supports Your DAS
The 8864 Data Controller
Every Alliance DAS — StackVision and Prism — operates in tandem with the 8864 Data Controller, our industry-standard hardware platform. The 8864 is the physical bridge between your emissions monitoring rack and your DAS software: it collects analog and digital signals from your analyzers, performs real-time calculations, and passes validated data upstream to StackVision or Prism for compliance reporting. One integrated system. One point of accountability.
