SiSA™ Alert Software
The command-and-control core of mass notification. Trigger, manage and audit alerts across every channel and device from a single, intuitive interface — on-prem or in the cloud.
Learn MoreHQE Systems engineers, integrates and supports the full stack of mass notification, emergency communications and electronic security technology. From the software that triggers an alert to the sirens that carry it across miles, every solution below is built, deployed and serviced under one roof — by one accountable team.
Each line stands on its own — and connects to the rest. Deploy a single piece, or let HQE architect the whole environment so alerting, communications and security operate as one coordinated system.
The command-and-control core of mass notification. Trigger, manage and audit alerts across every channel and device from a single, intuitive interface — on-prem or in the cloud.
Learn MoreHigh-powered outdoor warning that does more than wail. Crystal-clear voice messaging, remote diagnostics and self-test reach populations across miles — even when the grid is down.
Learn MoreA unified ecosystem that ties alerting, sensors, sirens and security into one coordinated response fabric — so a single event triggers the right action across every connected system.
Learn MoreLayered, perimeter-to-core physical protection for high-value and high-threat sites. Engineered hardening, access control and surveillance built to government and military standards.
Learn MoreVideo surveillance, intrusion detection, access control and integrated monitoring — designed, installed and serviced as one cohesive system, not a patchwork of disconnected devices.
Learn MoreThe AI-powered operating system that runs not only HQE itself, but also clients that chose to unify their entire emergency management operations through a single secure tenant.
Learn MoreWe design and build our own software and hardware, so the pieces are made to work together — not forced to interoperate after the fact.
From specification through deployment to lifecycle support, a single team owns the outcome. No finger-pointing when a system has to perform.
Federal, military and municipal deployments demand rigor. Every solution is engineered, documented and supported to meet that bar.
