Greeley’s Local Security Integrator
Greeley runs on agribusiness, food processing, and energy, and it has the facility types that come with them: production plants, cold storage, fleet yards, and industrial sites spread across Weld County. Those are demanding environments for a security system. Cameras have to hold up outdoors and cover large footprints, access control has to manage shift workers and contractors, and the whole system has to keep running while the site does.
We have worked across Northern Colorado for four decades, and we serve Greeley from our Fort Collins office. That keeps a technician close enough to reach a site in Greeley, Evans, or the surrounding Weld County area without a dispatch coming from out of state. We design the system, install it, and service it with our own team.

The Facilities We Secure in Greeley
Greeley is not a single type of building, and each facility type has a different security problem. The city’s economy runs on food processing and agribusiness plants, cold storage and distribution, and energy-sector and industrial sites, where cameras have to hold up outdoors and cover large footprints and access control has to manage shift workers and contractors across a site that never fully stops.
We also work with healthcare facilities, higher education and school campuses, and municipal and county buildings across Weld County. Each carries different requirements, from HIPAA-adjacent access control in healthcare to large-footprint camera coverage on an industrial yard and the procurement rules that come with municipal and government buildings. We design around the facility rather than dropping in a 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 in Northern Colorado
ESI has protected Northern Colorado businesses, institutions, and municipalities for more than 40 years. Our Northern Colorado work includes Larimer County, the City of Fort Collins, the City of Loveland, and the Northern Colorado Regional Airport.
We hold CJIS certification for handling criminal-justice information, relevant to government and law-enforcement-adjacent work, and our team includes a state-licensed Master Electrician. Our fire alarm and low-voltage work is performed by NICET-certified technicians. We are an authorized dealer for Axis, Avigilon, Genetec, Gallagher, Salto, and AMAG, which is not something every integrator can say.
Why a Local Integrator Matters for Service in Greeley
A security system is only as good as the service behind it. When a camera goes dark or a reader fails at a Greeley facility, the question is how fast someone who knows the system can get there. Our technicians work in Northern Colorado, so a service call is handled by the same team that installed the system, not routed to a call center in another state.
That is also why so many of our systems move onto a service agreement: the facilities that depend on the system want the same people maintaining it. We offer service agreements with preventive maintenance that replace unpredictable break-fix costs with scheduled service and priority response, and we service systems other integrators installed. Our commercial security system maintenance guide walks through what scheduled service should cover.
Frequently asked questions
Does ESI have an office in Greeley?
ESI serves Greeley from its Fort Collins office, which covers Greeley, Evans, Windsor, and the surrounding Weld County area. Our technicians are based in Northern Colorado, so service calls are handled locally rather than dispatched from out of state. Call (970) 999-1681 to reach the Fort Collins team.
Can ESI service a security system another company installed in Greeley?
Yes. ESI takes over service on systems installed by other integrators, including access control, camera, and alarm systems. We assess the existing system, tell you what is worth keeping, and offer a service agreement to maintain it going forward.
What kinds of Greeley facilities does ESI work with?
Food processing and agribusiness plants, cold storage and distribution, energy and industrial sites, healthcare facilities, education campuses, and municipal buildings. Each has different security requirements, and ESI designs around the facility rather than applying a standard package.
How quickly can ESI respond to a service call in Greeley?
Response depends on the issue and whether the facility is on a service agreement, which carries priority response. Because ESI’s technicians are based in Northern Colorado, a service call in Greeley does not wait on a dispatch from another state. Call (970) 999-1681 to discuss coverage for your facility.
