Windshield-mounted vehicle anti-theft apparatus and methods for using same

A vehicle theft-prevention system, comprising:

• a plurality of sensors configured to sense measurements proximate to a vehicle;
• and
• a body configured to permanently secure to a window of the vehicle and comprising:
• a wireless transceiver;
• and
• at least one computing device coupled to the plurality of sensors and the wireless transceiver, the at least one computing device configured to:
• receive, via the wireless transceiver, an indication to enter an armed mode from an unarmed mode;
• and
• in response to the indication, transition to the armed mode, wherein transitioning to the armed mode comprises setting a configuration of at least one property of a subset of the plurality of sensors.

A vehicle theft-prevention apparatus, comprising:

• a body configured to permanently secure to a window of a vehicle via an adhesive and comprising:
• a first sensor configured to sense a first type of measurement in the vehicle;
• a second sensor configured to sense a second type of measurement in the vehicle;
• at least one computing device coupled to the first sensor and second sensor, wherein the at least one computing device configured to:
• read a plurality of measurements of the first type of measurement from the first sensor at a predetermined frequency;
• in response to one of the plurality of measurements meeting a predetermined threshold, read at least one measurement from the second sensor;
• and
• determine that a person has moved proximate to the vehicle based on the at least one measurement from the second sensor.
