What the system can support

Alarms, access and visitor entry.

Use alarms to monitor selected areas and access control to manage who can enter each door or gate.

Commercial side entrance with an intrusion alarm keypad and motion detector

Intrusion alarm systems

Know when selected areas need attention.

Intrusion alarm systems can detect activity at selected doors, windows or protected areas and present a system alert for review. Door and window contacts, motion detectors and glass-break detection are selected around the rooms, glazing and alarm system.

Access credentials & permissions

Give approved people a practical way to enter.

Cards, fobs, PINs or other selected credentials let approved people enter designated doors. Permissions can be configured so the same credential opens approved doors while restricted spaces—such as laboratories, server rooms or records rooms—remain locked.

Intercom & visitor entry

Connect visitors with the right person before entry.

Audio or video intercoms can connect visitors, drivers and deliveries with a designated person before a controlled door or gate is released. Entry phones serve apartment arrivals; gate, dock and receiving intercoms help staff coordinate deliveries.

Gate, garage & vehicle access

Make approved arrivals easier to manage.

Controlled vehicle and pedestrian entry can follow approved credentials, permissions and designated release steps for the doors and gates your site uses. Cards and long-range vehicle tags, including visor-mounted options, can support parking and garage access with compatible readers.

Apartment locks & elevator access

Control access to homes and selected floors.

Wireless lock options for individual apartment doors help manage resident access. The choice depends on the door hardware and access system.

Manage access to selected floors with credential permissions, where supported by the elevator system.

Sensing cable mounted to a metal perimeter fence

Perimeter detection

Monitor the boundaries of your site.

Fence and perimeter detection helps monitor fenced yards and site boundaries. The fence layout, surroundings and alarm system determine suitable sensor options and how staff receive alerts.

Visitor signing in at a staffed reception desk

Visitor registration & reception

Support visitor check-in at reception.

Visitor check-in can support reception teams in care facilities and other managed buildings, with a compatible terminal where needed. Registration, staff access permissions and controlled door release serve different parts of the arrival process.

Alarm Monitoring

Plan what happens after an alarm signal.

Discuss monitoring alongside the alarm system, including the signals to be monitored, the people to contact and the response arrangements for your property.
