Littleton’s Local Security Integrator
Littleton is the Arapahoe County seat and it carries a mix of building stock that ranges from historic downtown storefronts to modern medical and aerospace facilities. Downtown Littleton has commercial tenants in buildings a century old where cable pathways are limited and the historic district review process affects what you can mount on a facade. That is a real design constraint, and it is one that gets discovered on a site walk rather than a drawing.
West and south of downtown the profile changes to aerospace and defense-adjacent facilities, hospital and medical office around the Littleton hospital campus, and industrial along the South Platte. Those sites have security requirements driven by their own compliance regimes, and the integrator has to fit into a program that already exists.

- Commercial security system design and installation. Surveillance, intrusion detection, and enterprise VMS for Littleton businesses.
- Access control. Card, mobile, and biometric credentials on Genetec, Gallagher, AMAG, and Salto platforms, for single doors up to multi-building campuses.

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 Littleton
Arapahoe County operates courts and administrative facilities in Littleton, and facilities that handle criminal justice information have to be built and serviced to CJIS standards. ESI’s technicians are CJIS cleared for that work.
The commercial base also includes AdventHealth Littleton and the medical office buildings around it, Arapahoe Community College, Littleton Public Schools, retail at Aspen Grove and along Broadway, and light industrial and distribution along the South Platte corridor. We install and support systems for municipal and government, healthcare, education, and industrial facilities in Littleton.
ESI’s History and Credentials in Colorado
ESI has operated in Colorado since 1984. We carry NICET certification for fire alarm work, employ CJIS-cleared technicians for facilities that handle criminal justice information, hold preferred vendor agreements with three Colorado municipalities, and participate in OMNIA Partners cooperative purchasing, which lets eligible government, education, and commercial buyers procure through an existing competitively bid contract.
Our work includes Larimer County, the City of Fort Collins, the City of Loveland, Northern Colorado Regional Airport, and the State of Colorado Integrated Document Solutions facility in Denver, where we consolidated 69 cameras onto a single managed platform. Those are the facility types we support across the Front Range: county and municipal government, transportation, and institutional clients that need systems installed correctly and maintained over time.
Why a Local Integrator Matters for Service in Littleton
Historic downtown buildings and 1970s commercial stock share a problem: the security system was added later, in layers, by different companies. A Littleton building will often have three generations of hardware on one site, with a panel nobody has the software for and a camera system on a recorder that stopped getting firmware updates years ago. Sorting that out starts with documenting what is installed, which is the first thing we do on a service agreement.
We offer service agreements with preventive maintenance, which replace the unpredictable cost of emergency break-fix calls with scheduled service and priority response. If your Littleton facility runs its security systems on a break-fix model now, a service agreement is worth a conversation. Our commercial security system maintenance guide walks through what scheduled service should cover.
