System History

History of ELV Systems

From analog infrastructures to integrated IP-based platforms, ELV has evolved to unify safety, security, communications, and building intelligence.

Overview

ELV (Extra-Low Voltage) systems encompass structured cabling, CCTV, access control, intercom, and building communications. Their evolution mirrors broader shifts from analog to digital, on-prem to cloud, and siloed systems to integrated platforms.

Structured cabling standards (TIA/EIA) unify deployments
PoE accelerates device rollouts and simplifies power
Cloud dashboards centralize monitoring and orchestration
Cybersecurity and compliance drive modern architecture

Timeline

1970s–1980s: Analog cabling and discrete systems (PA, intercom)
1990s: Early digital controllers; structured cabling standards
2000s: IP networking for CCTV and ACS; PoE adoption
2010s: Cloud-based management, mobile credentials, unified dashboards
2020s: AI analytics, edge processing, open integrations
