Rialto, CA
Remote security for Rialto warehouses and job sites
Rialto is still building out. Sigma watches its distribution centres, truck yards and construction sites remotely, around the clock, with live agents and AI detection.
Local and live
A city of new distribution centres
Rialto sits between Interstate 10 and the SR-210 Foothill Freeway, with Fontana, San Bernardino, Bloomington and Colton on its borders. Much of its recent growth came from large distribution centres, including in the Las Colinas area. The city's Renaissance Specific Plan covers about 1,445.3 acres, land that included the Rialto Municipal Airport, and allows for 15.4 million square feet of business and commercial uses.
Growth on that scale creates two kinds of sites to protect. Construction lots hold equipment and materials on open ground, often with no one there after the crews leave. New warehouses fill their yards with trailers and containers, sometimes before a security routine is settled. Both need eyes on them at night and on weekends, when a site can sit empty for hours.
For a Rialto job site, AI person and vehicle detection flags anyone on the lot after hours, an agent gives a live, instant talk-down through the site's speakers, and police are called if needed. Once a building opens, monitoring can grow into remote gate operations and yard checks, with damage inspections, visual seal checks on video and parking reports. Every incident comes with video evidence and a report.

FAQ
Rialto monitoring questions
Can you monitor a Rialto construction site before the building is finished?
Yes, as long as the site has power and an internet connection for the cameras. After hours, AI person and vehicle detection flags anyone on the lot, and an agent gives a live, instant talk-down and escalates to police if needed.
What do we receive after an incident?
Video evidence and a report of what the agent saw and did, including any call to police or fire.
Can the same service cover the warehouse once it opens?
Yes. Monitoring can add remote gate operations, where agents see arrivals and speak to drivers through the site's speakers, and yard checks: damage inspections, visual seal checks on video and parking reports.
