Smart Lock Integration & Custom Security System

Smart Lock Integration & Custom Security System

Access Control, Sensors, Alarms & Unified Management Platform

Client

The client was looking for a fully customized smart security system that could be installed across multiple different buildings and facilities such as offices, hotels, homes, and institutional properties. Goal: modern access control, door sensors, alarms, and central management — simple, secure, and built for long-term use.

The Challenge

  1. 01
    No Unified Access System

    The client had multiple buildings with different door types, making it difficult to manage all access points consistently through one centralized platform.

  2. 02
    Mobile Access Needed

    They wanted staff, contractors, and visitors to conveniently access buildings using a simple mobile app that worked reliably across all property locations.

  3. 03
    Remote Unlock Requirement

    The client needed the ability to remotely unlock any door in real time, ensuring quick access support without physical presence.

  4. 04
    Sensor & Alarm Integration

    They required dependable integration with door sensors and alarms to instantly detect unauthorized entry, tampering, or unusual activity across all sites.

  5. 05
    Time-Based Access Rules

    The system had to support scheduled access windows for different teams, allowing permissions based on working hours, shifts, or temporary contractor needs.

  6. 06
    Cloud Admin Portal & Apps

    A user-friendly cloud dashboard and mobile apps were needed to manage users, roles, permissions, and event logs from anywhere at any time.

  7. 07
    Multi-Brand Lock Compatibility

    They wanted a platform compatible with various smart lock brands and hardware types so everything could work smoothly without replacing existing devices.

  8. 08
    Use Existing Hardware

    The client needed the system to integrate with current locks and equipment, avoiding costly hardware upgrades or complete replacements across their properties.

Our Solution

We designed and delivered a complete smart access control and security platform that worked across various lock vendors and device types.

Key components we built:

  • Mobile apps (iOS & Android) for access, remote unlock, and user management
  • Cloud admin portal for roles, permissions, time schedules, and event logs
  • Multi-brand lock integration using SDKs/APIs from Nuki, Salto, TTLock, Kerong, Ajax and others
  • BLE, NFC, and Wi-Fi gateway support for seamless remote and offline unlocking
  • Door sensor integration for real-time door open/close status
  • Alarm system integration (two-way communication for armed/disarmed states)
  • Backend services for secure identity, tokens, permissions, and audit trails
  • Relay module control for gates, garages, and sliding doors

This platform acted as a unified security layer over all hardware, regardless of brand.
