Remote yard and site monitoring in Flagstaff
Flagstaff's truck yards, warehouses and construction sites get a live set of eyes from Sigma: agents on every camera around the clock, a driver check at the gate, and a call to police with video in hand whenever it's needed.
Local and live
Freight where I-40 meets I-17
Flagstaff sits where I-40 and I-17 meet, at exit 195 on the city's east side, and the BNSF Railway's Seligman Subdivision carries freight through town as part of the Southern Transcon, the rail line linking Southern California and Chicago. Industrial space keeps filling in around those routes: the city has set aside about 31 acres next to Pulliam Airport for the Northern Arizona Technology Park, built for manufacturing, research and logistics tenants with direct access to I-17, I-40 and State Route 89A, and a manufacturer now runs an aluminum automotive parts plant there, a $60 million investment expected to reach about 350 jobs, inside the city's former Walgreens distribution centre.
Arizona's vehicle theft count fell to a record low in 2025, 12,686 vehicles statewide, down 25 percent from 17,010 the year before, but the freight moving along I-40 through Coconino County is still a target. On May 29, 2026, Coconino County Sheriff's Office detectives arrested two men after a BNSF train was broken into near Meteor Crater, west of Winslow, and recovered more than $500,000 in stolen merchandise; two more suspects got away near Williams. Detective Curtis Peery said the county sees eight to twelve such train burglaries a month, and that August his team also recovered about $400,000 in cargo pulled from two trailers stopped on I-40 and I-10 within 20 minutes of each other. For a yard or lot along that stretch of I-40, an unwatched trailer or loading dock overnight carries the same exposure.
At a Flagstaff site, the camera feed doesn't go unwatched between shift changes. An agent is on it live, around the clock and all year, so when AI flags a person or vehicle after the crews have left for the night, someone is already looking rather than reviewing the clip in the morning. From there it's a live, instant talk-down through the speakers, and police get called in with video evidence already in hand. Drivers get the same attention at the gate: an agent checks them against your list before letting them in, and Yard Operations keeps a record of trailer condition and seals for loads moving through.

FAQ
Flagstaff monitoring questions
Can you watch a yard near the Northern Arizona Technology Park or the I-40/I-17 interchange?
Wherever the site sits in Flagstaff, an agent is already looking at that camera, not catching up on a recording the next morning. AI detection flags a person or vehicle the moment it appears after hours, the agent reviews it live, and a talk-down goes out over the site's speakers if someone needs to be told to leave. Coverage holds through nights, weekends and holidays, all year.
Who lets a driver in if our Flagstaff gate isn't staffed at night?
A Sigma agent does, through Gate Operations. They watch the camera as the truck pulls up, speak to the driver over the gate speakers, match the name against your pickup list, and release the gate from wherever they're working. The time, an image and the outcome are logged automatically, and unlisted drivers don't get in.
Flagstaff is a long way from Sigma's base in Ontario. Does that change anything?
Not for the monitoring itself, since agents work from your site's internet connection rather than a local office. What does take a visit is the install: a Sigma technician comes out to put in the cameras and speakers you need, and will connect compatible ones you already have rather than replace them. From there, keeping the power, the internet and the gate running is on your side.
