Yard and equipment monitoring in Fresno, California

Local and live

Freight on Highway 99 in the nation's top farm county

Fresno is the most populous U.S. city not directly linked to an interstate. Interstate 5 was built down the west side of the Central Valley, so State Route 99 is the main north–south freeway tying Fresno to the valley's other cities, with State Routes 41, 168 and 180 heading out toward Yosemite, Clovis and Kings Canyon. BNSF and Union Pacific both run main lines that cross in Fresno and keep rail yards in the city, and the San Joaquin Valley Railroad runs branch lines west and south.

Agriculture drives the yards. Fresno County's 2024 crop report put farm production at a record $9.03 billion, the most of any county in the United States, with almonds, grapes and pistachios at the top. That output moves through packing houses, cold storage and trucking yards. The tractors, harvesters and almond conditioners behind it are costly, and they often sit parked in yards, fields and orchards between jobs. One tractor and conditioner pair the sheriff recovered in September 2026 was valued at $265,000.

When equipment goes missing, investigators look for video. In its September 2026 release, the Sheriff's Office asked anyone with relevant surveillance footage to come forward. Sigma's agents watch equipment, packing and trucking yards live, 24/7/365. AI person and vehicle detection points them to movement, they use live, instant talk-down through your site speakers, and they call the sheriff or police when someone keeps going. Each incident comes with saved video and a report you can hand to investigators.
