Dimension
Initialization
When powered on,sensor indicator will turn off after flashing for 10S and will not detect moving signal during this time. After 10S,you can use our MH10 remote or dip switch to adjust detection area、hold time and daylight sensor etc parameter.
Factory setting
Detection Area: 100%, Hold Time: 5s, Daylight Sensor: Disable
