Customer Type:
Metropolitan Office of Emergency Management & Communications (OEMC),
serving a population of over 1 million residents.
Environment:
A centralized OEMC responsible for 9‑1‑1 call‑taking, dispatch, and radio communications for multiple public safety disciplines, supported by a fully equipped backup communications facility to ensure continuity of operations during major incidents, high‑volume events, and infrastructure disruptions.
Operational Requirements
The OEMC operates a large‑scale, high‑availability communications environment with requirements that include:
- Continuous recording of radio, 9‑1‑1, and administrative telephony
- Support for thousands of simultaneous recording channels
- Zero tolerance for downtime in mission‑critical systems
- Geographically separated primary and backup recording environments
- Centralized access to recordings for investigation, compliance, quality assurance, and incident reconstruction
Exacom Solution
The OEMC deployed the Exacom HindSight fault‑tolerant digital logging recorder platform to support enterprise‑scale recording across its communications operations. The system was originally installed in 2012 and remains operational following a major hardware refresh completed in 2019. The OEMC is also expected to undergo an additional hardware refresh in 2026.
The Exacom solution records audio from:
- P25 radio communications
- 9‑1‑1 call audio
- Administrative and non‑emergency phone lines
System Architecture & Scale
The OEMC operates a fully redundant recording architecture spanning both its primary operations center and a dedicated backup facility.
| Recording Environment | Approximate Channel Count |
|---|---|
| Primary OEMC facility | ~1,200 channels |
| Backup communications facility | ~1,236 channels |
| Total environment | ~2,436 channels (with redundancy) |
Key architectural characteristics include:
- Full recording redundancy between sites
- Centralized access to all recordings regardless of capture location
- Designed to scale for high‑volume metropolitan public safety operations
Results & Outcomes
- More than a decade of continuous operational use
- Proven ability to support thousands of recorded channels
- Fully redundant primary and backup recording environments
- Centralized, CAD‑integrated access to audio
- Long‑term system stability in a large metropolitan OEMC setting
