Which type of detector is known for its ability to work in adverse weather conditions?

Microwave detectors are recognized for their ability to function effectively in various adverse weather conditions. These detectors operate by emitting microwave signals and measuring the reflections that return after bouncing off objects within their range. Unlike some other detection systems that may be significantly impacted by rain, fog, or snow, microwave detectors can penetrate weather elements much better. This capability allows them to maintain consistent performance regardless of environmental factors, making them a reliable option in situations where visibility is poor.

In contrast, other types of detectors such as inductive loop detectors can be affected by water accumulation or pavement conditions, video detection systems may struggle with low visibility scenarios, and infrared detectors can be hindered by heavy rain or fog that blocks their infrared signals. Thus, microwave detectors stand out for their resilience and reliability in challenging weather, ensuring effective vehicle detection regardless of external conditions.
