Industry Challenges

The security challenges construction and outdoor teams face every day

Equipment Theft

U.S. construction sites lose over $1 billion in equipment annually. Without perimeter surveillance and controlled access, heavy machinery, tools, and materials are targets the moment your crew leaves for the day.

Unauthorized Access

Managing dozens of subcontractor crews with rotating personnel, expiring scopes, and shared access is a compliance and safety liability. Paper sign-in sheets don't stop an unvetted worker from entering a restricted zone.

After-Hours Vandalism

Unmonitored perimeters invite trespassers, vandals, and copper thieves after dark. A single overnight incident can set a project back weeks and drive up insurance premiums for the life of the build.

Before Kastle VideoGuarding, we had an on-site guard who could only cover one entrance. Now the SOC monitors every corner of the site around the clock — and it costs less than that single guard. We had zero unauthorized access incidents across the entire build.

Customer Story

KastleMobileSentry® Replaced On-Site Guards — at Lower Cost

Swinerton deployed KastleMobileSentry® VideoGuarding across a large commercial build, replacing a costly on-site guard program with 24/7 remote SOC monitoring. Temporary mobile credentials replaced paper sign-in sheets for every subcontractor firm — auto-expiring when each trade completed scope. The Kastle SOC responded to after-hours perimeter alerts before local security could be dispatched, and the project finished with zero unauthorized access incidents.

Security built for how construction projects actually run

Every Kastle solution for construction and outdoor environments is designed for the reality of active job sites — temporary access, rotating crews, and perimeters that change as the project evolves.

Temporary Mobile Credentials for Subcontractors

Issue smartphone-based credentials to every subcontractor firm on your project — tied to their active scope of work. No hardware to return, no badge printing, no shared fobs. When a trade wraps, their access expires automatically.

  • Apple Wallet and Google Wallet credentials — no app to download
  • Credential expiration tied to contract period
  • Per-firm, per-zone access configuration
  • Real-time access log for every entry and exit

More Effective Than On-Site Guards — at a Fraction of the Cost

A single on-site guard watches one entrance. KastleMobileSentry® VideoGuarding puts Kastle SOC specialists on every camera, every perimeter, around the clock — for less than the cost of guard staffing. When an after-hours intrusion is detected, SOC coordinates law enforcement response with live video, not a radio call from a guard who may have missed it.

  • SOC specialists monitor every camera and access point — not just one entrance
  • After-hours response with live video evidence, not after-the-fact recording
  • Law enforcement coordination in real time, with footage already pulled
  • One platform covers multiple active projects simultaneously
