Remote site monitoring in San Antonio

Local and live

Between the border and the rest of Texas

San Antonio sits where I-35, the trade route north from Laredo, crosses I-10 between El Paso and Houston, with I-37 heading toward the coast and Loop 410 circling the city. Port San Antonio, a 1,900-acre campus about five minutes from downtown, has 350 acres of railyard with direct access to BNSF and Union Pacific and an 11,500-foot runway. Greater SATX lists advanced manufacturing and logistics among the region's target industries, and the Toyota Motor Manufacturing Texas plant on the far south side builds Tundra pickups and Sequoia SUVs, with suppliers on its site.

Construction sites around the city carry their own risk after dark: building materials, tools and equipment left in the open overnight. A ring that Bexar County deputies broke up in 2026 had been working construction sites two to three times a week, according to the Sheriff's Office. Truck yards and warehouses along I-35, I-10 and Loop 410 face the same overnight exposure, with trailers and equipment parked in the open overnight.

Sigma watches construction sites and yards the same way: live agents on every camera, 24 hours a day, 365 days a year, with AI person and vehicle detection to flag anyone on site after hours. The agent verifies it on video, gives a live, instant talk-down through the site's speakers and calls police and your contacts, and you get video clips and a written incident report. Every quote costs less than a 24/7 guard, nights, weekends and holidays included.
