4D radar helps anticipate people's behaviour by detecting their position, distance, velocity, and direction of motion. This data can be used for faster reactions in anomalous situations and also for optimising smart automation systems. 4D radar is an exceptional sensor for institutions, offices, and public spaces, since the measurements cannot be used for people identification. Point cloud can, however, be used to observe separate entities. 4D radar is a sensor for smart buildings and cities, where data enables improvement of services, cost-efficiency, and safety.

Directional motion detection: innovative sensor technology
For example, automatic doors are made to open as a person moves towards them. The energy savings for properties are significant when the doors do not open unnecessarily as people pass by.
Unlike many other sensors, 4D radar is based on radio frequencies from 60 to 64 GHz rather than detecting sound or light, and it does not require audio or optical input.
.
4D radar can pass through plastic, fabric, and light structures. Detection of humans and animals is based on wave reflection from the target.
.
Measurements are accurate despite external conditions, as 4D radar works in smoke, fog, dark, backlight, and so on.
.
4D radar protects privacy
4D radar is an exceptional sensor for spaces that require monitoring without breaching anonymity, since the measurement data does not allow identification.
Abnormal motion can be used to trigger an alarm on a mobile device.
.
Accurate point cloud measurements can be used for detecting both moving and stationary entities..
.
Inconspicuous, wireless installation is possible as a “junction box”, flush mounted on a wall, or in a ceiling.
4D radar observes the number of people precisely
Data can be used for city planning, guiding people, and defining necessary bypass routes.
4D radar separates people from the point cloud mathematically. The maximum velocity for detection is 80 km/h.
Did you know this about mmWaves?
Millimetre waves are electromagnetic radiation included in the radio waves of the electromagnetic spectrum at the frequency of 60 – 64 GHz. mmWave radar technology is based on sending modulated radio waves as chirp signals, with frequency growth as a function of time. An object’s location, distance, and velocity relative to the sensor can be determined from the phase difference of the return signals. The radar’s circuit board can have two (2) to seven (7) sender/receiver antennas.
4D Radar technical specifications
Radar with an auxiliary processing unit that can be connected to a network and a display, depending on the application.
