Light-on-Demand - Motion Sensor Street Light


Street lights illuminate only in the presence of a human. Rest of the time, they burn at a pre-defined economical level, for instance, at 20%.

Neighbor Trigger

When a pedestrian, cyclist or a car is detected, the sensor not only illuminates a single street light but up to 10 surrounding street lights!

The surrounding street lights keep on illuminating as the road user passes by, keeping him/her in a safe circle of light.

Once the user passes, street lights return to their predefined brightness.

Additional Energy Savings

Additional Energy Savings

LED street lights deliver about 50% energy savings than traditional street lights.

Retrofitting LED street lights with smart wireless controllers provides 60-70% energy savings.

Pairing our motion sensors with smart controllers offers up to 80% energy savings.


Our street light motion sensors are capable of collecting data on the local human traffic movement. You can view this data in a comprehensible heatmap format in our CityManager software suite.




The sensors enable on-demand lighting by automatically adjusting the brightness of the lamps according to human presence.

Advanced Human Detection*

The sensor allows filtering non-human movement, like that of animals or wind. Lamps will only react to human activity, e.g. to pedestrians, cyclists and cars.

*Available in CitySense Plus only.

Full Remote Management & Control

You can read and control CitySense Plus / Lite lamps through our own software, CityManager, or any suitable third-party software.

Easy to Install

The sensors are effortless to install and can be integrated easily into the existing lighting infrastructure. Offers universal lamp compatibility.

Weather Resistant

Like other Tvilight intelligent street lighting products, CitySense Plus and CitySense Lite were developed to withstand harsh outdoor environments.


CitySense Plus and CitySense Lite can perform traffic density monitoring without additional sensors. The generated heatmap shows the relative traffic density based on the number of relevant triggers received.

Neighbor Trigger

Upon detection of human presence, the sensors trigger all lights in the surrounding areas turn to a pre-defined brightness level, visually creating a safe circle of light around the occupant.


Both sensor options have a 3-level back-up system. In an unlikely case of a system failure, lamps will return to the brightness of 100%.
