Abstract
Security keypad device for detecting tampering includes a keypad, a high power wireless module for communicating data via a local area network, a low power wireless module communicating data via a personal area network, and a cellular module for communicating data via a wide area network. The device further includes an active infrared position sensor comprising of a light source for emitting infrared light and an infrared sensor for detecting reflected infrared light. The active infrared position sensor is configured to sense the position of the device based on detecting the reflected infrared light. The device further includes an accelerometer configured to measure acceleration forces and a processor. The processor is configured to determine that the position of the device changed based on positional data from the active infrared position sensor or acceleration data from the accelerometer.
