Port-area yard monitoring in Oakland, California

Local and live

Northern California's container gateway

The Port of Oakland loads and discharges more than 99 percent of the containerized goods moving through Northern California, across four marine terminals, two intermodal rail facilities and 18 deep-water berths. Union Pacific runs its Oakland intermodal terminal on Middle Harbor Road around the clock. Trucks leave the waterfront through the MacArthur Maze, where Interstate 80 and Interstate 580 meet Interstate 880, the Nimitz Freeway, which runs south toward San Jose.

South along I-880, the industrial belt through Oakland, San Leandro and Hayward is oriented toward the port. A 2026 industrial real estate review describes its users as third-party logistics providers, food and beverage distributors, last-mile delivery and port-related businesses. Those sites hold containers, chassis and loaded trailers, often in tight urban lots beside busy streets and freeways, with trucks coming and going through the day.

Sigma's agents watch those lots live, 24/7/365. AI person and vehicle detection flags someone at the fence or between container rows, and agents use live, instant talk-down through your site speakers before calling police. For pickups, agents see each truck arrive, speak to the driver through the speakers and open the gate remotely. Yard checks record damage, visual seal checks on video and parking positions, so you know which boxes and trailers are in the yard and in what condition.
