Gate Sentry offers cutting-edge, primarily hardware-free mobile access control for a variety of properties, both manned and unmanned. For locations with on-site security, our Gate Sentry software simplifies visitor check-in via a tablet system, with SentryPass providing secure mobile guest verification. For unmanned properties, like self-storage facilities and remote gates, our Sentry Solo system delivers powerful, cost-effective access using VirtualKey and VirtualKeypad technology, enabling smartphone-based entry for authorized users and QR code/unique code access for visitors, eliminating traditional hardware.
