What are the differences between pDetect, pRecognize, and pBehavior?

These products build on top of each other. pDetect detects the presence of a person. pMonitor, in addition, recognizes the faces you have placed on the Safe List or the Watch List. pSafety detects anomalous behaviors such as loitering, slip and fall, and mask compliance.  You can turn the notification off/on for each type of alert separately based on your preference.
