What door readers do

The first step in every access event

Readers are the devices people use to unlock doors, gates, elevators, offices, amenity spaces, storage rooms, and secure areas. A reader checks the credential being presented — a card, fob, phone, wallet credential, PIN, or visitor pass — and sends that request to the access control system.

With Alocity, a reader is not just a device on the wall. It becomes part of a smarter access, video, visitor, and AI workflow.

One unlock. A complete access event.

With Alocity, Signo readers connect into one platform for users, credentials, doors, schedules, access logs, video events, alerts, reports, and AI workflows.

Works with existing Wiegand and OSDP readers

Multiple credentials, one platform

The right access experience for every user, door, and space

For employees, access becomes faster and easier. For visitors and vendors, temporary access can be issued, limited, tracked, and revoked. For administrators, credential management becomes simple — add users, issue credentials, change permissions, suspend access, review history, and manage doors from the cloud.

Alocity makes access flexible without making it complicated.

Readers are just the beginning

Every unlock becomes a searchable, video-linked event

Manage users, credentials, schedules, doors, visitors, access events, video, alerts, reports, and AI workflows from one platform. Every door can be managed remotely. Every access pattern can become an insight. And with Aimee, teams ask questions and execute approved actions in plain English.

"Show me who entered the west lobby after 8 PM."

"Suspend John's mobile credential until Monday."

"Create a visitor pass for FedEx from 10 AM to noon."

"Show all failed access attempts at the warehouse this week."

Alocity connects the reader at the door to the intelligence of the entire platform.
