What a Group One intrusion system includes
Every system is built around your building's layout, entry points, and hours. A typical installation includes:
Intrusion detection built for your building
One local team handles design, installation, and monitoring.
Door & Window Protection
Contacts on entries and accessible windows, with a signal the moment one opens unexpectedly.
Motion Detection
Interior sensors placed for your layout and traffic, so real intrusions trigger and false alarms do not.
Glass-Break Sensors
Protection for storefronts, display windows, and ground-floor glass.
24/7 UL-Listed Monitoring
Signals go to a trained dispatcher who verifies and dispatches, not a phone alert you might sleep through.
Cellular & Battery Backup
Monitoring continues through power and internet outages, when a closed business is most exposed.
Camera & Access Integration
An alarm event, the video of it, and the door it came through, all in one system.
Where intrusion detection fits
We design detection around the specific needs of the facility.
Retail & Restaurants
After-hours protection for storefronts, stockrooms, and cash areas.
Offices & Professional Services
Coverage for entries, server rooms, and records areas.
Warehouses & Industrial
Perimeter and interior detection for larger properties.

Protection for medication storage, records, and equipment.

Intrusion alarm questions
What happens when the alarm goes off?
The signal goes to our UL-listed monitoring team, where a trained dispatcher verifies it and dispatches law enforcement, 24 hours a day.
Will the system work during a power or internet outage?
Yes. Cellular and battery backup keep the system reporting when power and internet fail, which is exactly when a closed business is most exposed.
Can we protect specific areas separately?
Yes. We can zone the system so different areas arm and report independently, useful for multi-tenant or mixed-use buildings.
Does it integrate with cameras and access control?
Yes. Intrusion, video, and access run as one system with one point of contact.
Can you take over monitoring of our existing alarm?
In most cases, yes. We evaluate the equipment and either take over monitoring, upgrade it, or replace it.
How do false alarms get handled?
Proper sensor selection and placement cut false alarms, and our dispatchers verify before dispatching to reduce unnecessary responses.
