One partner for commercial security systems in Chicago

A commercial security system covers access control, video surveillance, visitor and vendor management, and threat deterrence.

• Access control determines who can enter which floors, suites, and common areas at what times.
• Video surveillance verifies that the person using a credential is the one authorized to use it.
• Visitor and vendor management handles contractors, delivery couriers, and guests through pre-registration, ID verification, and time-limited access.
• Deterrence measures such as exterior lighting, staffed lobbies, and visible cameras at entry points reduce the number of incidents the other three categories need to detect and address.

In a managed system, all four categories operate on one platform.

Yes. Kastle's cloud-based platform allows one credential to work across every building in a portfolio. An employee badge or mobile credential that provides access to the lobby at one property also opens authorized doors at any other property on the same system. Administrators manage permissions, pull reports, and respond to alerts from a single dashboard.

Yes. Kastle integrates with third-party readers, credentials, cameras, and building management systems. Existing cameras can connect to a Kastle gateway for cloud-based management and AI-powered video analytics without replacing the installed hardware. A site assessment identifies which existing components can carry over and which need upgrading.

Kastle supports mobile credentials through Apple Wallet, Google Wallet, and Samsung Wallet. Employees carry their building access on the phone they already have. Mobile credentials are harder to duplicate or transfer than physical keycards and can be issued or revoked remotely without collecting a physical badge.

Yes. Kastle plans upgrades in phases, so every zone of the building remains protected throughout the transition. Tenants, visitors, and deliveries continue moving through the property while new hardware is being installed. Each device is tested on-site under real occupancy conditions, and a scheduled review after go-live identifies any gaps. Many commercial buildings in Chicago's Loop and West Loop were built before cloud-based access control existed, so a phased approach keeps tenants protected while legacy panels are replaced.

Kastle protects commercial office buildings, multifamily residential communities, enterprise campuses, construction sites, parking structures, healthcare facilities, government buildings, and more. Kastle has been in business for over 50 years, protecting more than 10,000 properties and 60,000+ businesses across the United States and Australia.

Start with a free on-site security audit. A Kastle team member walks your property, evaluates every entry point and camera position against current conditions, and identifies where your existing setup has gaps. The audit covers the full building, from the parking structure and loading dock to individual tenant floors. There is no cost and no obligation.
