PIR sensors are devices that perceive motion by detecting the heat that's generated by a moving human body. Common applications of...
What is a PIR Sensor? PIR sensor detects a human being moving around within approximately 10m from the sensor. This is an average value, as the actual detection range is between 5m and 12m.PIR are fundamentally made of a pyro electric sensor, which can detect levels of infrared radiation. ...

When opioid peptides such as beta-endorphins are released in the brain, they are known to cause a decrease in sensitivity to pain. Beta-endorphins, which are morphine-like substances, are synthesized or produced in various areas of the brain. One such area is the hypothalamus, an area involv...
Note: Activity Zones or Privacy Zones won’t affect the PIR sensor, thus these settings can’t reduce the wake-up times. What is Wake-up Sensitivity? Generally, Wake-up Sensitivity refers to the camera's sensitivity to PIR sensor triggering. Higher sensitivity results in longer detection distan...
