A smart relay vehicle alarm system is shown and described. The smart relay vehicle alarm system includes a first sensor, such as a microphone, installed upon a vehicle. The first sensor is electrically coupled to a microcontroller. The microcontroller can send a signal via a wireless transceiver to an associated mobile device when the first sensor is activated. In one embodiment, the smart relay vehicle alarm system includes a monitoring system. The wireless transceiver will send the signal to the monitoring system instead of the associated mobile device. The monitoring system will forward a signal to the associated mobile device when the first sensor is triggered via a vehicle alarm.

A tracking system can provide intervention notifications to a user to notify the user that a tracking device is potentially lost or is in a predicted state. The tracking system may notify the user that a tracking device is potentially lost or in a predicted state based on a number of factors, including: a proximity of a tracking device to other tracking devices or a user's mobile device, a movement of a tracking device to more than a threshold distance away from a mobile device or other tracking devices, a location of a tracking device relative to a geographic location or to geographic boundaries, a usage or movement behavior of the tracking device, a usage or movement behavior of a user or owner of a tracking device, information received from an external source, or information received from sensors within the tracking device or a user's mobile.

A detector includes a housing having a window. A detection engine is configured to detect an event external to the housing. A battery is connected to the detection engine and configured to supply power thereto. A solar cell is configured to generate electricity when exposed to a light received through the window. The solar cell is arranged in the housing and electrically connected to the battery.

Methods, systems, and apparatus, including computer programs encoded on a storage device, for enabling drone activity in a property monitored by a property monitoring system without triggering a false alarm. In one aspect, the method includes actions of obtaining a location of the drone, identifying a first sensor installed at the property that is within a predetermined distance of the drone, detecting first sensor data generated by the first sensor that is within a predetermined distance of the drone, wherein the first sensor data includes data that is indicative of an event, determining whether a second sensor that is mounted to the drone is generating second sensor data that corroborates the event indicated by the first sensor data, and disregarding, by the property monitoring system, the first sensor data in determining whether to trigger an alarm.
