Remote yard monitoring in Vacaville

Local and live

Distribution space at the I-80/I-505 interchange

Vacaville sits at the junction of Interstate 80 and Interstate 505, where I-505 splits north toward Interstate 5 and Sacramento while I-80 continues on toward the Bay Area. A logistics development of roughly 124 acres near Midway Road and I-505 grew in two phases: a distribution building of about 843,000 square feet went up on the site of a former grocery-chain distribution centre, and a second building of about 617,000 square feet, built for a large e-commerce fulfilment operation, followed in 2021. That scale of pallet-in, pallet-out trucking has made trailer yards and staging lots a regular feature around the interchange.

Across California, the Highway Patrol's 2025 theft report counted 7,331 stolen trailers and more than 1,800 stolen commercial trucks for the year, exactly the kind of equipment that sits overnight in staging lots at distribution centres like the ones along I-505. Separately, cargo-theft trackers have named California the state with the most reported cargo-theft incidents nationally, with warehouses and parking lots cited as the most common theft locations. For a trailer yard or dock near the interchange, an unwatched lot overnight is enough for a cut seal, a missing trailer or a damaged door to go unnoticed until the next shift arrives.

Sigma's agents watch every connected camera live, 24 hours a day, including nights, weekends and holidays, and AI person-and-vehicle detection flags any movement in the staging lots for a person to check before anything is called in. Once a person is confirmed on camera where they shouldn't be, the agent doesn't wait: a live, instant talk-down goes out over the yard's own speakers immediately, and police or fire get the call if the person stays instead of moving on, with a clip and written account kept for the client afterward. For incoming trucks, the process runs through an agent rather than a card reader: the driver's name goes against the client's pickup list or schedule, they're spoken to over the gate's speakers, then waved through remotely, with the arrival logged for the dispatcher. Agents also handle truck and trailer damage checks and visual seal checks on video, with yard and parking reports telling the morning shift what moved overnight. A free assessment settles whether Vacaville's existing cameras can be wired in as-is or new ones go up, handled either way by Sigma's technicians, while power, an internet connection and a gate stay the site's own responsibility.
