Zetron Communication Recording Systems: Operational Traceability in Control Centers

Why recording is operationally critical

In a traffic control center — air, maritime, rail, mining, or emergency — every communication is an operational event with real consequences: takeoff authorization, track entry permission, emergency report, evacuation instruction. Recording is not a supplement: it is the traceability infrastructure that enables incident investigation, regulatory compliance, and operator training.

Regulatory requirements

Aviation (ICAO Annex 11): All ATC voice communications must be recorded with 30-day minimum retention, UTC synchronization to 1-second precision, and access within 1 hour for accident investigation. In Peru, CORPAC operates under DGAC supervision with mandatory ICAO compliance. The technical standard is EUROCAE ED-137 for VoIP ATC communications.

Maritime (IMO/SOLAS): Recording of distress and safety communications (VHF Channel 16, GMDSS) is required at maritime rescue coordination centers. In Peru, authority is DICAPI.

Mining (OSINERGMIN): DS 024-2016-EM and mining safety regulations require communications traceability for blasting operations, emergencies, and evacuations.

Rail: Ferrocarril Central and PeruRail concession agreements require recording of train movement authorizations with precise timestamps for correlation with train logs and signaling systems.

Zetron recording systems

Zetron (Eaton group) provides professional-grade recording platforms for critical infrastructure control centers.

Zetron ADAM: Central recording server capturing up to 64 simultaneous analog channels plus VoIP SIP/RTP. Key capabilities: contextual search by date/time/channel, 30-minute instant recall without interrupting active recording, SHA-256 evidence packages for legal chain of custody, and automatic integration with Zetron Acom/Aria console dispatch metadata.

Zetron Aria: IP dispatch console with integrated per-seat recording (up to 32 channels per operator position), suitable for small-to-medium centers.

Architecture essentials

Multi-channel concurrent capture supporting VoIP SIP/RTP, analog 4-wire, E1/T1, conventional radio discriminator audio, P25 digital, and TETRA. Timestamp precision requires NTP/PTP (IEEE 1588) synchronized to GPS/Stratum-1 source with < 1ms accuracy — a timestamp drift > 2 seconds from UTC reference can render a recording legally questionable in accident investigation. Storage dimensioning: a 32-channel ATC center recording G.711 audio for 90 days requires approximately 1.9 TB before redundancy — provision minimum 6 TB with RAID-6 and off-site backup.

Key technical specifications for procurement

When drafting technical specifications: minimum simultaneous channels (define from source inventory), maximum latency from event to replay availability (< 5 seconds recommended), RTO < 4 hours with on-site spare components, EUROCAE ED-137 certification for IP ATC, multi-factor authentication for recording access, AES-256 storage encryption, RAID-6 minimum for critical systems, and automatic off-site backup (daily or continuous by criticality).

Emar Systems provides and implements Zetron recording systems including architecture design per entity-specific regulatory requirements (DGAC, DICAPI, OSINERGMIN, SUTRAN), installation and integration with existing dispatch consoles, operator and administrator training, and post-sale support with documented response time guarantees.
