Abstract:
A trespass prevention alarm configured to prevent someone from breaking into a house through a balcony or a window and a trespass prevention method. The alarm comprises: a first sensing unit, configured to sense a movement direction of a person; a second sensing unit, configured to sense a movement of an indoor person in a predefined range in a sense area (1) of the first sensing unit; a controller, configured to determine, according to sense results of the first sensing unit and the second sensing unit, a trespass condition; and an alarm circuit, configured to operate when trespass is determined. The above alarm can differentiate trespass and a normal activity of an indoor person without setting or resetting an alarm, and has a low false alarm rate.
