Smart City Implementation in Kežmarok

The city of Kežmarok has taken a major step toward becoming a smarter, more connected urban environment. The goal of the project was to establish a centralized system for monitoring and managing key components of public infrastructure — specifically, waste container fill levels, street lighting performance, and city camera system data. 

This solution is powered by our Ambrella IoT platform, which provides city administrators with a unified, real-time view of all connected devices — including sensors, lighting units, and surveillance cameras. Ambrella enables centralized management, data visualization, and automatic issue detection across various city systems. 

Softigo was responsible for the solution design, integration of the deployed devices, full system implementation, and platform configuration. 

Ambrella collects and processes data from a wide range of devices such as streetlights, cameras, parking systems, and smart waste sensors — forming the foundation of Kežmarok’s intelligent city management. 

System Integration 

Ambrella has been seamlessly integrated with both internal and external systems to maximize interoperability: 

Internal systems: 

• City surveillance  
• Parking management 
• City data portal – publicly accessible dashboards and open datasets 
• Street lighting control system 
• Smart waste management system 

External systems: 

• Open Data module (data.gov.sk) – for publishing open government data 

All connected devices communicate via NB-IoT or LTE, transmitting data to Ambrella’s secure cloud infrastructure. The platform uses PostgreSQL for configuration data and InfluxDB for time-series telemetry, enabling robust and scalable data processing. 

Key Modules Deployed 

The following Ambrella modules were implemented as part of the project: 

• Digital Object Manager 
  Maintains records of physical and virtual devices, locations, lookup tables, and defines data models for each device type. 
• Monitoring 
  A configurable status dashboard showing real-time technical data from all devices. 
• Flow 
  A visual data processing and automation tool for system integrations, including incident rules, camera triggers, and parking logic. 
• Dashboard 
  Data visualization through customizable widgets — charts, maps, video feeds, iframes, and text blocks. 
• Parking Management 
  Full administration of parking zones, pricing, permits, tickets, and real-time occupancy status. 
• API Manager 
  Enables the creation and publishing of data sets via web services (CSV/JSON), with automatic updates. 
• Notifications 
  Custom rule-based alerts delivered via SMS or email in case of device malfunctions or critical system events. 
• REST Adapter 
  Technical interface for ingesting data via HTTP/REST from external sensors and devices. 

Platform Capabilities 

In addition to core modules, Ambrella provides essential enterprise-grade features: 

• Access & Security 
  Comprehensive user, group, and role-based access control ensures secure system management and data protection. 
  
• Logging 
  Advanced auditing and system logs with search and filter functions to support transparency and traceability. 
  
• Notifications 
  Rapid response to critical events through automated SMS/email alerts. 
  
• Reports & Analytics 
  Built-in reports provide insights into device performance and operational metrics to support data-driven decision-making. 

This project is a cornerstone in the city's effort to modernize public services and urban operations. With Ambrella at its core, Kežmarok is enhancing operational efficiency, fostering sustainability, and becoming a more livable and resilient smart city.
