This time, we would like to introduce the "Snow Accumulation Prevention Cover (PSP-SCV)" and the "Snow Accumulation Prevention Reflector (PRF-300SP)." When snow accumulates on the surface of a microwave sensor, it may not be able to detect properly depending on the amount of snow. To prepare for such situations, we have the "Snow Accumulation Prevention Cover (PSP-SCV)" available. *Applicable sensors: BSS01, BSS20, BLS01, BFS01 By attaching this to the sensor, you can prevent snow accumulation on the sensor body. Additionally, when installing the microwave intrusion detection sensor (BSS01) facing the reflector, we also have the "Snow Accumulation Prevention Reflector (PRF-300SP)" designed to prevent snow accumulation on the reflector. By using these products together, normal detection is possible even in heavy snowfall areas.

At Pal Giken, we are developing various sensors that use "microwaves," and this time we will explain how they detect intrusions. ◆◆ Two Detection Methods ◆◆ Our microwave sensors support two detection methods. 1) Beam Reflection Detection Method A single sensor is installed, and the transmitted wave output from it defines the detection area. The detection range depends on the antenna angle of the sensor, but the sensor alone covers a wide distance. When a target intercepts the transmitted wave from the sensor, it is received as a reflected wave and detected as an "intrusion." 2) Beam Interruption Method This method configures the detection area by positioning the sensor and reflector opposite each other. The transmitted wave output from the sensor hits the reflector and is received as a reflected wave. There are also products that configure the detection area using a transmitter and receiver. In this case, the transmitted wave output from the transmitter is received by the receiver. In both cases, the levels that serve as the basis for transmission and reception are monitored, and if the wave is interrupted due to an intrusion, causing the level to fall below a threshold, it is detected as an "intrusion."
