Security System Engineering in Decatur, IL

Decatur is central Illinois' ag-processing capital, home to ADM's North American headquarters and massive corn and soybean processing operations, with industrial construction dominating the local pipeline.

What we engineer

Electronic security system design per NFPA 731 — access control (card/fob, biometric, and mobile credentials on OSDP readers), video surveillance (ONVIF cameras, PoE/PoE++ infrastructure, NVR/VMS storage architecture with retention engineering), and intrusion detection (UL 681 panels, sensors, and monitored alarm transmission per UL 827); access-controlled egress designed to IBC requirements — electromagnetic locks that release on fire alarm and power loss with compliant panic hardware.

Facilities we design for

Schools (Alyssa's Law panic-alert integration, controlled entry vestibules, visitor management), cannabis facilities (state-mandated surveillance retention and limited-access-area alarming), commercial buildings, houses of worship, and industrial sites — plus UL 2050 high-security design for government and critical-infrastructure work.

Backed by licensed PEs

All security system engineering is backed by Apex Grid Engineering: 10+ PEs licensed across 49 states, 20+ engineers, 15+ years of plan sets that pass plan check.
