    Access Control & PropTech

    Access Control Software Development — Smart Buildings, Resident Apps & Multi-Vendor Hardware Integration

    Access control is one of our flagship practice areas — we've shipped connected-community access systems that work when the WiFi is down, the resident is locked out at 11pm, and the property manager needs an audit trail that holds up in court. PropTech is the broader category around it.

    What we hear from Access Control & PropTech teams

    • Access events fail silently when the building's network blips — residents get locked out and the call goes to the on-call ops team
    • Hardware vendor lock-in: every new building or lock model means rewriting half the integration layer
    • Audit logs that don't capture offline events properly — the gap shows up the day legal asks for one
    • Credential lifecycle gaps: residents move out but their access lingers for weeks because nothing reconciles the leasing system with the access layer
    • Permission models that can't express 'cleaner has Tuesday access between 9–12 with override from any owner'
    • Resident churn from a janky mobile app where guest-pass invites take 9 taps
    • Compliance gaps around resident PII and access-log retention
    • Property managers using 3 different dashboards because nothing integrates

    Regulation & compliance we work with

    GDPR (EU resident data + biometric processing rules)
    CCPA & state-level US privacy laws
    Fire-code & life-safety integration requirements (free-egress, fail-safe behaviour)
    ADA / accessibility (resident-facing apps + physical access)
    ASSA ABLOY / SALTO / dormakaba / Latch integration standards
    OSDP v2 for secure reader-controller communication
    BACnet / Modbus interoperability for broader building systems

    What we deliver

    Resident & tenant-facing iOS + Android apps with biometric unlock, BLE / NFC credentials, and offline-tolerant guest-pass flows
    Multi-vendor access-control gateways — a single domain model on top of ASSA ABLOY, SALTO, dormakaba, Latch, and BLE-OEM hardware
    Property-manager web dashboards with multi-property + multi-tenant RBAC down to the unit and door
    Audit-grade access logs designed to survive legal review — offline events captured, signed, and reconciled
    Offline-tolerant credential architecture (signed tokens, cached entitlements) so doors keep working when the network drops
    Leasing-system integrations (Yardi, AppFolio, RealPage, Buildium, Entrata) — so move-outs revoke access in minutes, not weeks
    Visitor management, package-room workflows, intercom + amenity-booking modules
    Hardware-in-the-loop test suites — because integration bugs only show in physical buildings

    FAQ

    Do you integrate with our existing access-control hardware, or do we have to swap it out?
    We integrate with what's installed. Across past engagements we've shipped adapters for ASSA ABLOY, SALTO, dormakaba, Latch, and BLE-based locks from Asian OEMs. The pattern is a gateway service that normalises hardware events into a single domain model so the resident app and property dashboard don't care which lock is on which door — and a new hardware vendor is a single adapter to write, not a rewrite of the platform.
    What happens when the building network goes down?
    The product still has to let residents in. We design access flows with offline-tolerant credentials (signed tokens, cached entitlements) and the gateway reconciles events when connectivity returns. The audit log treats offline events as first-class — they aren't lost. We test this on physical hardware on every PR that touches the credential or gateway layer.
    How do you handle audit trails for legal / compliance scenarios?
    Every access event — successful, denied, offline-reconciled, manually overridden — is signed, timestamped, and stored immutably. The audit-log service is designed to be subpoena-ready: queryable per unit, per resident, per time range, with vendor-event correlation so you can reconstruct exactly what hardware did what at any moment. We've handled requests from law-firms and insurance carriers on prior projects.
    How do you test against physical hardware?
    Hardware-in-the-loop staging: we keep a rack of representative locks, intercoms, and gateways in our office and run integration tests against them on every PR. Builds that touch the hardware adapter layer can't merge without passing the rack tests. This is the single biggest reason our access-control projects don't break in the field.
    Can you handle multi-property portfolios?
    Yes. Multi-property is a first-class concept — properties, units, residents, staff, and vendors are modelled separately, with portfolio-level reporting overlaid on top. RBAC is hierarchical (portfolio → property → unit → resident), and access policies can be inherited or overridden at any level.
    Do you only do residential, or also commercial / mixed-use?
    Both. Residential is where our flagship case study lives, but the same platform pattern (gateway-normalised hardware, offline-tolerant credentials, audit-grade logs) applies to commercial offices, mixed-use developments, hospitality, and gated communities. The biggest deltas are visitor workflows, integration to building-management systems, and life-safety / fire-code requirements.
