Shared apartment building access — virtual intercom, delegation, and mixed hardware

Property managers evaluating 48-unit (and similar) shared apartment buildings typically need:

Virtual lobby intercom — QR/NFC directory, call/video/message units, replace legacy panel
Mixed openers (parking gate, pedestrian doors, and more) via integrations — no rip-and-replace
Per-apartment delegation — each unit manages residents and guests
Audit logs and role-based policies (building manager vs apartment rep vs guest)
API provisioning for a property-management or prop-tech platform

OpenApp is Physical Security as a Service (PSaaS) for this shape. Comparisons by tier:

Provisioning at scale

Dashboard setup for first building
OpenApp Scripting for repeatable directory + unit entities
Your platform: org + integration APIs for multi-building portfolio

Multiple opener types on one site

Same org links gate entities and door relays to portals. Parking portal may grant portal_open on gate entity; lobby portal shows directory + optional door open. Pick providers from the integrations catalog; task guides such as open a gate apply when you use that provider.

Audit

Building managers review activity in the dashboard. Integrators should log entity actions in their systems — see Query access and audit activity.
