This time, we would like to introduce the differences in detection methods of our microwave sensors. We hope this will serve as a reference for customers who are unsure about which sensor to choose or want to know the type that suits their application. There are mainly two detection methods for microwave sensors: "beam reflection method" and "beam interruption method." The "beam reflection method" detects changes in the reflection of microwaves emitted from the sensor when they hit a person or object. It can be operated with a single sensor, making installation smooth and easy, even in limited spaces. Next, the "beam interruption method" involves placing the sensor and a reflector (or transmitter/receiver) opposite each other to detect the moment when the radio wave path is "interrupted." This method is ideal for situations where a clear monitoring line, such as a fence line, needs to be established, and it is widely used for perimeter security and gate monitoring. *For more details, please download the PDF or feel free to contact us.

In Japan, wrong-way driving accidents remain a significant safety issue on highways. Every year, a certain number of incidents related to wrong-way driving occur, and the fact that they are prone to lead to serious accidents, such as head-on collisions, is problematic. The proportion of elderly drivers involved in wrong-way driving is high, and misjudgments, overlooking signs, and assumptions are considered the main factors. Locations where wrong-way driving is likely to occur include interchanges, toll booths, and entrances and exits of service areas and parking areas, where the proximity of entrances and exits makes the structure difficult to understand. There are also cases where drivers attempt to return after passing an exit on the main road, leading to wrong-way driving, making early detection of abnormalities crucial. In response to these issues, measures utilizing sensor technology have been advancing in recent years. The microwave safety monitoring sensor can detect distance and speed using microwaves, allowing for stable monitoring even at night or in bad weather. By detecting wrong-way vehicles early and linking them to warnings and control coordination, it contributes to the prevention of serious accidents and the overall improvement of road safety.

In the protection of artworks and cultural properties, in addition to preventing theft and vandalism, the most important aspect is to safeguard the works without causing damage. While there is a demand for monitoring that does not involve touching the artworks, the installation and operation of cameras can often be challenging due to privacy considerations and installation constraints. Furthermore, there is a need to reliably detect intrusions or approaches during nighttime or after hours, as well as to quickly identify signs of not only theft but also vandalism, damage, and removal. Against this backdrop, there is a growing demand for sensors that possess the characteristics of "not handling images," "not making contact," and "being less affected by environmental factors." As an option, the use of microwave sensors that can detect intrusions and approaches without contact is considered effective. These sensors detect human movement and proximity through changes in radio wave reflection and can operate stably even in dark environments. They can detect behaviors such as "reaching out to the exhibit," "crossing the rope," or "being too close" and provide immediate notifications. They serve as an additional detection layer that complements existing security systems, contributing to deterrence and early response. They are also effective in enhancing security around exhibition rooms, storage areas, and various entrances and the periphery of buildings.

At campsites and glamping facilities, while there is the charm of spending time in nature, there is also a lingering anxiety about theft and intruders. Many facilities implement measures such as nighttime patrols and security cameras, but there are also voices seeking even greater peace of mind. In this context, by utilizing microwave sensors and image analysis units as a means to complement existing measures, it is possible to detect human intrusions and suspicious movements in real-time, enabling stable monitoring even in darkness or adverse weather conditions. The system that "detects abnormalities and alerts" supports the prevention of troubles before they occur. It watches over safety in harmony with nature, providing peace of mind for both users and facilities. An environment where guests can stay with peace of mind leads to increased satisfaction and repeat rates, reduced patrol burdens, and improved efficiency in nighttime management. It can also address less visible risks, supporting the creation of facilities that are chosen by customers. 【Usage Scenarios】 - Monitoring intrusions around tent sites - Watching over entrances and shared spaces - Detecting suspicious individuals and behaviors in parking lots 【Benefits of Implementation】 - Prevention of theft and troubles - Enhanced sense of security for users
