Understanding Probability of Detection and Time-to-Detection: The Continuous Monitoring Advantage

For continuous monitoring, Probability of Detection (PoD) can be framed as a function of time. Detection confidence grows with each measurement window. Here we explain how controlled-release testing and time segmentation translate PoD into Time-to-Detection (TtD) and contrast that with single-pass survey methods. For operators, this provides a practical way to set expectations for how quickly a continuous system will find different-sized events and why that matters for response.
