Commercial Security Systems in Centennial

The Facilities We Secure in Centennial

ESI installs and services commercial security across Centennial’s office-heavy base: office and corporate campuses, professional-services and technology tenants, business-aviation and aerospace-adjacent facilities, multi-tenant buildings, retail, and education.

Centennial’s office and corporate concentration means access control, video, and AV usually have to integrate cleanly and scale across a campus, which is the work we do. Whether the site is a corporate campus, a light-industrial or aerospace-adjacent facility, or a public building, we design around the building rather than a fixed template. For a deeper look at how the pieces fit together, see our guide to commercial access control systems in Colorado.

ESI’s History and Credentials

ESI has installed and serviced commercial security systems in Colorado since 1984. We dispatch our own technicians to the Denver metro from our Colorado Springs office and keep a documented service history on the systems we maintain, including systems other integrators installed.

We hold manufacturer authorizations from Axis, Avigilon, Hanwha, Genetec, Gallagher, Salto, and AMAG, and we carry CJIS compliance for government and law-enforcement work. Our team includes a state-licensed Master Electrician, licensed through Colorado DORA, and our fire alarm and low-voltage work is performed by NICET-certified technicians. We hold preferred vendor agreements with three Colorado municipalities and offer cooperative purchasing through OMNIA Partners.

Why a Local Integrator Matters for Service in Centennial

A corporate office runs on its systems being up. When access control drops or a conference room’s AV fails before a meeting, the longest part of the problem is usually the wait for a qualified technician. A national call center or a subcontractor arrangement adds a handoff to every service call.

We dispatch our own technicians to Centennial from Colorado Springs, keep a documented service history, and can service equipment other integrators installed, so a facility on break-fix can move to scheduled service without starting over. Our service agreements put that on a schedule, and our commercial security system maintenance guide walks through what scheduled service should cover.

Frequently asked questions

Does ESI have a Centennial office?

ESI serves Centennial from its Colorado Springs office, which covers the Denver metro. Centennial projects get a dispatched ESI technician and a documented service record rather than a subcontractor. Northern Colorado is served from our Fort Collins office.

Can ESI manage access control across a multi-building corporate campus?

Yes. One access control platform manages credentials, door schedules, and reporting across every building from a single system instead of building by building. Mobile credentials reduce the badge churn that comes with tenant and staff turnover, and access can be added or revoked without rekeying a door.

Can ESI service a system another company installed?

Yes. We maintain access control, video, intrusion, and fire alarm systems installed by other integrators, and we can move a system off break-fix onto a scheduled maintenance agreement. A site walk tells us what you have and what it needs.

What access control and camera brands does ESI install in Centennial?

Access control on Genetec, Gallagher, AMAG, and Salto. Video from Axis, Avigilon, Hanwha, and i-PRO recorded on Milestone, Genetec, or Avigilon. Being authorized on these platforms is what gives you manufacturer support, warranty coverage, and current firmware over the life of the system.
