Security teams on the ground in San Francisco

Kastle covers San Francisco and the surrounding Bay Area, including Oakland, Berkeley, Daly City, South San Francisco, San Mateo, and Redwood City. Theft risk shifts by neighborhood and by phase of a build, so coverage that works downtown may leave an outlying yard exposed. That is why a local presence and a national operations center work together. Crews who know the San Francisco metro deploy and service your cameras, and a round-the-clock center verifies alerts and acts on them the moment something moves.

One partner owns every step

We design, install, monitor, and maintain your coverage

On most San Francisco sites, coverage fails for one reason. Once the job is underway, no single team is responsible for keeping the system live. Kastle closes that gap. We assess the site, design the camera layout, deploy the units, watch the feeds, and move coverage as the footprint changes. San Francisco property crime fell to its lowest level since 2001 in 2024, yet larceny still drove more reported volume than any other crime category through 2025. Coverage protects a site only when one team is accountable for it day to day.

Site assessment and system architecture for mobile surveillance in San Francisco

Where cameras go decides what they catch, so Kastle starts with the site itself. We walk your San Francisco location, pinpoint where theft and access risk concentrate, and position coverage over the gates, laydown yards, and equipment areas that draw the most attention. Vehicle theft weighs heavily in that plan across the Bay Area, which accounted for roughly 25.36% of all California vehicle thefts in 2024, with 7,202 recorded in San Francisco. Lots and staging areas stay exposed long before a structure is closed in, so the layout accounts for them early.

  • Camera placement scoped to your site's phases, not a template.

  • Blind spots found during the walk, before they cost you.

  • A design that credentials staff and subcontractors from day one.
