Abstract: A vehicle theft-prevention system can include a plurality of sensors configured to sense measurements proximate to a vehicle and a body configured to secure to a window of the vehicle. The body can include 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 can be configured to receive, via the wireless transceiver, an indication to enter an armed mode from an unarmed mode. The at least one computing device can be configured to, 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.

Abstract: A sensing device can include at least one sensor, positioning circuitry, a transceiver, and a computing device in communication with the at least one sensor, the positioning circuitry, and the transceiver. The computing device can determine a location of a vehicle via the positioning circuitry. The computing device can determine that a point of interest (POI) associated with a predefined category of POIs corresponds to the location. The computing device, via the transceiver, can determine that a person is moving away from the vehicle based on a measurement associated with a remote device. The computing device can enter into an armed mode in response to the determinations. The computing device can detect an intrusion into a vehicle while in the armed mode based at least in part on measurements from the at least one sensor. The computing device can generate an alarm in response to the intrusion.
