CitySense Lite is a next-generation motion sensor street lighting control system designed to make public lighting more intelligent, adaptive, and sustainable. At its core, it combines low-power PIR motion sensors with smart street light controllers, enabling a responsive lighting solution that automatically adjusts brightness based on human presence. Fully compliant with Zhaga-D4i standards, CitySense Lite ensures true plug-and-play interoperability with certified controllers and luminaires from any manufacturer, making it a flexible and future-proof choice for cities and communities. Installation is seamless thanks to the Zhaga Book 18 standard, which allows for quick, tool-free mounting with a simple twist-and-lock mechanism. Meanwhile, D4i compliance guarantees that the sensor has its own power, simplifying deployment and ensuring reliability.
The system is designed with energy efficiency at its heart, offering energy savings of up to 80% through its light-on-demand feature. Unlike traditional street lights, which remain at full brightness regardless of activity, CitySense Lite brightens only when pedestrians, cyclists, or vehicles are detected. Once the area is vacated, the lights return to a predefined minimum level, striking the perfect balance between energy conservation and public safety. When paired with LED street lights, which already deliver around 50% energy savings compared to conventional options, and smart luminaire controllers that offer up to 70% savings, the addition of CitySense Lite motion sensors can push the savings even further while dramatically lowering CO2 emissions.
One of its standout safety features is the neighbor trigger functionality. When motion is detected, not only does the nearby light brighten, but adjacent street lights also adjust to a higher level, creating a safe circle of light around road users and enhancing their sense of security. This adaptive illumination reduces dark spots, improves visibility, and naturally boosts public confidence in outdoor spaces. An integrated ambient light sensor (ALS) further refines performance by tailoring light output according to available natural light, preventing unnecessary brightness and reducing light pollution. This sensitivity to the environment benefits both residents and nocturnal wildlife, ensuring more responsible illumination.
CitySense Lite also introduces powerful analytical capabilities through its built-in heatmap functionality. By monitoring motion sensor triggers across streets, pathways, and public areas, it generates valuable insights into traffic density and usage patterns without requiring additional sensors. These heatmaps help city planners and facility managers understand how spaces such as parks, bicycle lanes, university campuses, parking facilities, and residential areas are actually used. The data can reveal trends, pinpoint bottlenecks, and highlight popular areas, enabling optimization of lighting schedules and configurations to match real-world usage.
Maintenance and operational efficiency are further improved with CitySense Lite. Proactive alerts and notifications provide early warnings for faults, alarms, and outages, reducing maintenance costs by up to 70%. Asset management is supported through an open API, allowing integration with third-party software platforms for advanced monitoring and control. In addition, when paired with a smart driver, the system can collect detailed information about the luminaire, driver, and light source. This enables precise energy metering, diagnostics, and asset tracking, all of which contribute to smarter infrastructure management.
The weather-resistant design of CitySense Lite ensures reliable performance even under challenging outdoor conditions, withstanding rain, snow, dust, heat, and wind. This durability, combined with its easy installation and open-standards architecture, makes it a long-lasting investment. Cities are not locked into a single vendor, as the system can integrate with third-party compliant sensors, luminaires, and controllers, offering maximum flexibility. Remote management capabilities are available through the CityManager platform or any compatible third-party software, giving operators full control and visibility over their street lighting network.
By integrating motion detection, adaptive lighting, advanced analytics, and open-standard compatibility, CitySense Lite redefines what is possible with smart street lighting. It significantly reduces energy consumption, minimizes CO2 emissions, lowers maintenance costs, and enhances public safety, all while supporting the creation of smarter, more sustainable, and more livable cities.
