What We Do
Security, Fire Alarm, and AV Services for Colorado Businesses

Everything ESI Offers
From design and installation to monitoring and ongoing support, ESI handles every phase under one contract.

Surveillance cameras, intrusion detection, and enterprise VMS. Authorized dealer for Axis, Avigilon, Genetec, and more.
Video Surveillance
IP cameras, VMS, and storage from Axis, Avigilon, Hanwha, Genetec, and Milestone. Single-building installs to enterprise multi-site.

Card readers, mobile credentials, and enterprise access control platforms from Gallagher, Salto, AMAG, and Genetec. Single-door installs to enterprise multi-site deployments.
Intrusion Detection
Sensors, control panels, and 24/7 central station monitoring on Bosch, Gallagher, and Napco. Integrated with access control and video.
Fire Alarm Systems

AV Systems
Conference room displays, video conferencing, digital signage, and unified audio, designed and installed to match how your team works.
24/7 Monitoring
UL-listed central station monitoring with video verification. When an alarm fires, a person responds, not a voicemail.
Remote Guarding
Live agents monitor your cameras in real time and intervene with audio warnings before threats escalate. Active deterrence, not just recording.
Managed Security Services
Fully outsourced security management. ESI monitors, maintains, and manages your entire security program for a predictable monthly cost.
Managed Sites
Scheduled maintenance visits, priority response, and complete system documentation for facilities that already have a security system installed.
Maintenance & Service
Annual inspections, preventive maintenance contracts, firmware updates, and repair response to keep your system reliable long after installation.
Not Sure Where to Start?
A free site walk is the best first step. An ESI project manager visits your facility, identifies gaps, and recommends the right combination of services for your building and budget.
