this is a motion detector. it will sense movement and start an alarm which will ring for 3 times per movement sensed. The noise can be annoying, so use the UP arrow to open the settings (DO NOT PRESS THE SETTING ICON.IT IS ONLY A LIGHT TO INDICATE THAT SETTINGS IS OPENED). press the DOWN arrow to close the settings.
my recommended settings are the one which you see when you open the settings. .....................IMPORTANT POINTS............................ 1. setting the trigger rate to 0 will make the sensor to think that motion is always been made. 2. when you are in the settings menu, the sensor will still sense motion 3. changing the video transparency doesn't affect the sensor mechanics. 4. constant movement can make the sensor to produce irritating sounds. 5. setting the trigger rate to 100 will make the sensor to think that motion is never been made. ........................................................................................CREDITS>>>>>>>>>> all credits to me
