Johnstown’s Local Security Integrator
ESI designs, installs, and services commercial security systems for businesses in Johnstown from our Fort Collins office. We are a Colorado company that has installed and supported commercial systems across Northern Colorado since 1984.
Johnstown sits at the I-25 and US-34 interchange, and few Northern Colorado towns have grown as fast. The 2534 development, Johnstown Plaza, Ledge Rock Center, and the distribution and light-industrial buildings along I-25 have turned what was a small farm town into a commercial and logistics hub between Loveland, Greeley, and Windsor. Most of this is new construction, which means a lot of security systems are being specified and installed from scratch, and a lot of general contractors need an integrator who can work to a build schedule.
We work with Johnstown businesses on new installations and on the ongoing service of systems already in place, including systems other integrators installed.

The Facilities We Secure in Johnstown
ESI installs and services commercial security for the facility types driving Johnstown’s growth: distribution and logistics centers along I-25, retail centers and multi-tenant commercial property, light manufacturing and flex-industrial buildings, new-construction and tenant-improvement projects, medical and professional offices, and municipal and public buildings.
A distribution center needs perimeter and dock coverage plus access control across shipping, receiving, and office areas. A multi-tenant retail center needs surveillance on common areas and separate access control by tenant. Getting that right at the design stage costs far less than reworking it after occupancy, whether the project is a manufacturing or distribution facility or a municipal building. For a deeper look at how the pieces fit together, see our guide to commercial access control systems in Colorado.

Why a Local Integrator Matters for Service in Johnstown
Johnstown is largely new construction, and new construction rewards an integrator who is local and available. On a build, security cabling and device rough-in have to happen at the right point in the schedule, coordinated with the general contractor and the other trades. We dispatch from Fort Collins, a short drive up I-25, so we can be on site at the stages that matter instead of trying to fit our work in remotely.
Once a system is live, that same proximity keeps service fast. A distribution center or retail property with a camera down or a reader failing does not want to wait on a technician driving in from the Denver metro or out of state. We are close, and we service what we install. That continuity is why so many of our systems move onto a service agreement, and our commercial security system maintenance guide walks through what scheduled service should cover.
Frequently asked questions
Does ESI have technicians who cover Johnstown?
Yes. ESI serves Johnstown from its Fort Collins office, a short drive up I-25, with technicians who work throughout Northern Colorado. Service is handled by a local team rather than dispatched from out of state.
Does ESI work with general contractors on new construction in Johnstown?
Yes. Much of our Johnstown work is new commercial construction and tenant improvement. We coordinate structured cabling and device rough-in with the general contractor during the build so the security system is designed in from the start.
What kinds of Johnstown businesses does ESI work with?
We work with distribution and logistics centers, retail and multi-tenant commercial property, light manufacturing, medical and professional offices, and municipal buildings. ESI is a commercial integrator and does not install residential systems.
Can ESI service a security system another company installed?
Yes. We regularly take over service and maintenance for cameras, access control, and alarm systems that other integrators installed, including systems the original installer no longer supports.
