Denver Metro, Colorado
Commercial Security Systems in Denver
ESI Technologies serves the Denver metro from two Colorado offices: Fort Collins to the north and Colorado Springs to the south. Denver businesses get locally operated security with licensed technicians, faster response than out-of-state competitors, and the accountability that comes from a team that works in this state. ESI designs and installs commercial security systems: surveillance cameras, access control, intrusion detection, and 24/7 monitoring, for businesses across the Denver metro.

Security Services for Denver Metro Businesses
ESI Technologies is Colorado’s locally operated commercial security integrator serving Denver metro businesses from two Front Range offices with licensed technicians, local dispatch, and the kind of long-term service relationship that national companies can’t provide.
- Commercial Security Systems: Surveillance cameras, access control, and intrusion detection designed and installed for Denver metro businesses. We walk your facility, design the system, and install it — no cookie-cutter solutions.
- 24/7 Security Monitoring: UL-listed central station monitoring for your Denver facility. When an alarm triggers, our monitoring team responds immediately.
- Remote Guarding: Live operators monitoring your cameras in real time, intervening via audio before incidents escalate. Effective for parking lots, construction sites, and after-hours perimeter protection.
- Managed Security Services: Full outsourced security management: system, monitoring, guarding, and maintenance under a single managed contract.
- Managed Sites: Protect your investment with scheduled maintenance, firmware updates, and priority service — for existing ESI clients and systems installed by other integrators.
- Commercial AV Systems: Conference room displays, video conferencing, and digital signage installed alongside your security infrastructure by the same local team.
Two Colorado Offices Serving the Entire Front Range
Most security integrators serving Denver are based out of state or operate from a single office. ESI has two: our Fort Collins office serves the north Denver metro and our Colorado Springs office serves the south Denver metro. That means faster technician dispatch, local accountability, and a team that understands Colorado’s business environment.
We hold CJIS certification for security-sensitive environments, and our team includes a state-licensed Master Electrician. We’re an authorized dealer for Axis, Avigilon, Genetec, Gallagher, Salto, and other leading security manufacturers.
