Can microwave detectors penetrate materials like glass or wood?

Microwave detectors can indeed penetrate materials such as glass and wood due to the nature of microwave radiation. Unlike infrared sensors, which can be obstructed by physical barriers or materials that absorb infrared wavelengths, microwave signals are capable of passing through many non-metallic substances. This characteristic allows microwave detectors to effectively monitor areas even if there are obstacles present, making them versatile in various security applications.

The ability to penetrate these materials is a significant advantage in ensuring that the detection systems remain operational and effective in environments where certain barriers may otherwise inhibit performance. This functionality is why microwave detectors are often utilized in security systems, as they can provide reliable coverage and detection even with obstacles that would otherwise hinder other types of sensors.
