What methods are available for defeating passive infrared (PIR) motion sensors?

DSIAC was tasked with researching solutions to detect, counter/spoof, and neutralize commercial off-the-shelf (COTS) passive infrared motion sensors. With the assistance of subject matter experts (SMEs) at the Georgia Tech Research Institute (GTRI), a list of possible active and passive countermeasures to defeat PIR motion sensors was compiled and delivered to the inquirer.
