Abstract

ABSTRACT A tamper resistant motion detector is pr ovided that can include a housing, a capacitive sensor, and a microprocessor. The housing can include a window, and the capacitive sensor can be located inside of the housing, behind the window. A capacitance of the capacitive sensor can change when the capacitive sensor detects an object on the window or within a predetermined distance from the window, and the microprocessor can read the capacitance of the capacitive sensor and use the capacitance of the capacitive sensor to determine whether to activate an alarm or to determine whether to activate an anti-mask system.
