Frequently asked questions
Common questions about commercial security systems for office buildings and CRE portfolios.
A commercial security system combines technologies like access control, video surveillance, visitor management, and intrusion detection to protect office buildings and workplaces. Modern commercial security systems go beyond traditional security to help property owners improve tenant experiences, simplify operations, and respond quickly to incidents. Managed security providers like Kastle also design, install, monitor, maintain, and support the entire system, giving customers one partner for every aspect of building security.
There are several technologies that go into creating different types of commercial security systems, including:
Access control: manages who can enter buildings, suites, and secure areas.
Video surveillance: monitors activity and verifies incidents.
Visitor management: facilitates guest and vendor registration and check-in.
Remote video monitoring: responds quickly to alarms and security events.
Many modern building security systems are moving away from disparate vendors and adopting managed security services that handle all aspects of security under one partner.
The cost of a commercial security system depends on factors such as building size, the number of entry points, the technologies deployed, and whether the system is self-managed or leveraging security as a service. While traditional security solutions often include upfront costs and ongoing maintenance fees, managed security services offer predictable monthly pricing that includes equipment, software, monitoring, maintenance, and support.
Hybrid work has changed office security because businesses use their space differently. In many markets, Class A+ buildings have continued to attract tenants and command higher rents, even as the broader office sector adjusts to new ways of working – making flexible, data-driven security more important than ever. Companies are no longer basing their office security strategy on predictable daily occupancy. Today’s commercial property managers are weighing changing schedules, mobile-first access, easy visitor management, and insights into building activity.
