The sensor, developed by Siemens, is so small that it can be fitted to street lights and powered by them. They can also be attached to road poles or to the external walls of buildings. They can monitor an area about 30 metres long and 9 metres wide from a height, which is equivalent to about five to seven cars parked in rows. Unlike cameras and ultrasonic sensors, plastic housings can be used to protect the sensor without interfering with the beam. As a result, the sensor can blend into an urban environment without being noticed. "The sensors do have a lower resolution than conventional surveillance cameras, but they have other advantages, " Zwick said. Because of their low resolution, for example, they can only record sketchy images. "It protects the privacy of people on the road, " he explained. In addition, the sensors are less susceptible to fog, rain, changing lighting conditions and winter weather than ground-based sensors, and are more cost-effective. More features to be developed developing this high frequency sensor is a daunting challenge. The sensor must be able to communicate with its "colleagues" and small enough to be mounted to street lights, and it must be easy to manufacture and install. "The sensors, which consist of antennas, Analog Electronic Systems, Analog-to-digital converter and signal processing components, should be easily integrated into the city's infrastructure, " Florian said
