When the doorbell is used for saluting guests, install it at the top of the door or on the wall and adjust the detector to the suitable position, so when the guest comes into the detecting area it will sound automatically.

When the doorbell is used for alarming the detector should face such place that is easy for the thief to enter into as the balcony, the window and the stairway. The height of the detector should be in the proper range and the angle of the detector should be adjusted so that the device will alarm when the thief sneaks into the house.
