Use smart locks for single‑door retrofits and simple home use where basic remote unlock and user management suffice. Choose a professional access control system when you need multi‑door management, audit logs, staff access schedules and tighter integration with CCTV and building systems.

Some smart locks and platforms offer integrations with cameras and alarm systems, but full access control platforms provide more robust, auditable integrations and event‑driven automation that meets professional security and compliance requirements for multi‑door sites.

They typically require structured wiring, controllers and reader hardware which increases upfront cost, but they scale to many doors and users and provide centralised management and audit logs, making them cost‑effective for larger properties or where security and traceability are required.

Yes — hybrid approaches are common where smart locks are used on secondary doors and professional access control secures primary entrances. Careful planning of integrations, user management and fallback strategies is required to avoid administration complexity.

Plan for local failover, battery replacements for wireless locks, secure provisioning of user credentials, ongoing firmware updates, and integration with CCTV/alarm systems to ensure the chosen solution remains secure and manageable over its lifetime.
