Windsor’s Local Security Integrator
Windsor sits at the center of Northern Colorado’s fastest-growing commercial corridor, along US-34 and I-25 between Fort Collins, Loveland, and Greeley. That growth shows up as new construction and tenant improvement: light industrial and distribution buildings, commercial developments, and expanding facilities that need security designed in from the start rather than added after the fact.
New construction is where a local integrator earns its keep. Security has to be coordinated with the general contractor, rough-in has to happen at the right point in the build, and the cabling and conduit have to go in before the walls close. We serve Windsor from our Fort Collins office, close enough to be on site through a build, and we have done this across Northern Colorado for four decades. We design the system, install it, and service it with our own team.
Security Services in Windsor
ESI provides the full range of commercial security integration for Windsor facilities, specified during a build or added to an existing site, and the team that installs a system is the team that maintains it.
- Commercial security system design and installation. Surveillance, intrusion detection, and enterprise VMS for Windsor businesses, coordinated with the build.
- Access control. Card, mobile, and biometric credentials on Genetec, Gallagher, AMAG, and Salto platforms, specified during construction or added to an existing facility, from a single door to a full site.
- Video surveillance. IP cameras, VMS platforms, and storage from Axis, Avigilon, Hanwha, Genetec, and Milestone, sized for warehouses, yards, and commercial buildings.
- Intrusion detection and alarm systems. Sensors, control panels, and central station monitoring on Bosch, Gallagher, and Napco platforms.
- Fire alarm systems. Design, installation, and NFPA 72 inspection by NICET-certified technicians, coordinated with the rest of the build.
- 24/7 monitoring. UL-listed central station monitoring for Windsor commercial properties.
- Remote guarding. Live operator video monitoring for parking lots, yards, construction sites, and exterior zones.
- Managed security services. Outsourced security management for Windsor businesses.
- Managed Sites. Service contracts for existing security system owners in Northern Colorado.
- Maintenance agreements. Scheduled inspections and priority service for Windsor security systems.
- AV systems. Conference room AV and digital signage installation.
We hold manufacturer authorizations from Genetec, Axis, Gallagher, Avigilon, AMAG, and Salto. Authorization controls warranty coverage, software licensing, and the manufacturer support channel, which means we can program, license, and support these platforms over their full life, not just install the hardware.

The Facilities We Secure in Windsor
Windsor is not a single type of building, and each facility type has a different security problem. The growth here runs on light industrial and distribution buildings, new commercial construction and tenant improvements, manufacturing sites, and retail and mixed-use developments, each at a different stage of construction when we get involved.
A distribution warehouse and a new retail development need very different systems, so we design around the facility and the stage of the build rather than applying a standard package. We support manufacturing and industrial facilities and municipal and government buildings across the corridor, and coordinate directly with general contractors on new construction. 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 Windsor
On a new build, a local integrator can be on site when the schedule shifts and the rough-in window moves. After the build, that same closeness is what keeps the system running: when a camera drops or a reader fails at a Windsor facility, our Northern Colorado technicians handle the call, not a dispatch from another state.
That continuity is why so many of our systems move onto a service agreement, with the same team through the life of the system. 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 Windsor?
ESI serves Windsor from its Fort Collins office, which covers Windsor, Timnath, Johnstown, and the surrounding corridor. 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 coordinate security on a new construction project in Windsor?
Yes. ESI works with general contractors on new construction and tenant improvement, coordinating rough-in timing, cabling, and conduit so the security system is built into the project rather than retrofitted. Bringing ESI in early avoids opening finished walls later. Call (970) 999-1681 to discuss a project.
Can ESI service a security system another company installed in Windsor?
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.
How quickly can ESI respond to a service call in Windsor?
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 Windsor service call does not wait on a dispatch from another state. Call (970) 999-1681 to discuss coverage.
