1. A sensor device comprising:

  • a processor;

    power circuitry configured to receive a supply of power;

    a sensor configured to detect activity external to the sensor device;

    an accelerometer configured to detect relative movement of the sensor device; and

    a memory coupled to the processor, the memory storing instructions that, when executed by the processor, cause the sensor device to perform the operations of;

    monitoring, via the sensor, activity external to the sensor device;

    initiating a tamper monitoring state that includes monitoring relative movement data of the sensor device, the relative movement data received from the accelerometer;

    in response to detecting movement of the sensor device meeting a predetermined threshold of movement, executing a tamper detection response, the tamper detection response comprising;

    transmitting a notification that indicates sensor device movement meeting the predetermined threshold of movement; and

    initiating a low-power state of the sensor device.
