Can microwave detectors penetrate materials like glass or wood?

Microwave detectors utilize electromagnetic waves to detect motion and are capable of penetrating various materials, including glass and wood. This ability stems from the nature of microwave frequencies, which can travel through these materials without significant loss of signal strength. This penetration capability is advantageous in security applications, as it allows the detector to monitor spaces even when obstacles are present. Therefore, the statement that microwave detectors can penetrate materials like glass or wood is true.
