Remote yard and site monitoring in Denver
Live agents and AI cameras watch Denver truck yards, distribution warehouses and construction sites around the clock, from the I-25/I-70 interchange out along I-76.
Local and live
Freight where I-25, I-70 and I-76 meet
Denver sits at the junction of I-25, I-70 and I-76, with I-225 and I-270 carrying freight around the edges of downtown. Four freight railroads serve the metro, including BNSF and Union Pacific, which both run intermodal yards in the city. Denver International Airport moved 732,559,659 pounds of cargo in 2025, a record for the airport, with FedEx and UPS both running cargo operations there.
Colorado State Patrol's 2025 Auto Theft Annual Report counted 16,291 vehicles stolen statewide, down 34 percent from 2024, and the Denver Metro area, which includes the city and six surrounding counties, still accounted for 69 percent of that total. In June 2026, Colorado's Attorney General and the Denver District Attorney announced the indictment of 11 people accused of running a theft ring that stole 41 pickup trucks, trailers and recreational utility vehicles worth more than $900,000 from small municipal airports and nearby businesses across the Denver area between July 2024 and January 2025. For a yard owner, that's the same opening: equipment and trailers left outside with nobody watching.
Sigma assigns a live agent to every camera on a Denver yard, 24 hours a day, 365 days a year, rather than leaving footage to be reviewed once a trailer turns up missing. When AI person and vehicle detection flags someone near the fence line after hours, the agent checks the feed, gives a live, instant talk-down through the site's speakers, and calls police if the person doesn't move on. Each driver is checked against your pickup list under Gate Operations before the gate opens, and Yard Operations handles damage inspections and visual seal checks as trailers move through.
On the record: In June 2026, the Colorado Attorney General's office and the Denver District Attorney announced the indictment of 11 people on 52 counts for a theft ring that stole 41 pickup trucks, trailers and recreational utility vehicles, worth more than $900,000, from small municipal airports, hotels and businesses across the Denver area between July 2024 and January 2025.

FAQ
Denver monitoring questions
Can you watch a trailer yard along I-70 or near one of Denver's rail intermodal yards?
Yes. An agent keeps a live eye on your cameras around the clock, 365 days a year, nights, weekends and holidays included. The moment AI person and vehicle detection picks up movement, that agent verifies it on video and gives a live, instant talk-down through the site's speakers before calling police.
Can agents handle the gate for carriers picking up loads at our Denver site?
Yes, through Gate Operations. An agent watches for the driver's arrival, speaks to them over the gate speakers, and checks the name against your pickup list or schedule before letting the gate open remotely. Drivers who aren't expected are turned away, and the visit is logged either way.
Sigma is based in Ontario. How would a Denver yard get cameras installed?
The distance from Acton, Ontario doesn't change how the service works, since monitoring runs over your site's own internet connection. A free site assessment looks at your layout and any cameras already there, many compatible cameras can be connected, and Sigma's technicians travel out to install whatever the site still needs. You provide the power, the internet connection and the gate.
How do I get started?
Request a free site assessment or call (209) 900-5884 ext 2. A Sigma specialist reviews your layout, existing cameras and risks, then recommends the right coverage, at no cost and with no obligation. Every quote costs less than a 24/7 guard.
