Ontario, California: warehouses, rail and air cargo

Ontario, California calls itself the Inland Empire's hub of industry, a hub the city says is fed by the ports of Los Angeles and Long Beach. Its economic development office counts about 120 million square feet of industrial space and 240 logistics establishments. Interstate 10, Interstate 15 and State Route 60 cross the city and the area around it, and both BNSF and Union Pacific run freight rail through Ontario.

Ontario International Airport adds air freight to the mix. The airport reported 700,809 tons of freight and 134,319 tons of mail in 2025, with total air cargo up 5.3% on the year. Around the airport and along the freeways, that means warehouses with trucks arriving at all hours, trailers staged between runs, and long fence lines that one guard at the gate can't see.

Sigma covers the gate and the yard from a distance. Agents see each arrival on camera, speak to drivers through the site's speakers and open the gate the site provides. After hours, AI person and vehicle detection watches docks and perimeters, and agents give a live, instant talk-down and escalate to police or fire. Monitoring is remote, so there is no Sigma office in Ontario, California, and Sigma's technicians come out to install the cameras and speakers.
