A smart sensor early warning notification system. Certain aspects of the present disclosure provide for a smart sensor early warning notification system comprising a smart sensor coupled to a door and configured to detect one or more unauthorized access events, including sawing, blunt force and other atypical vibrations to the door. A smart sensor may be communicably engaged with a local alarm to communicate sensor data received at the smart sensor. The local alarm may be configured to process the sensor data received from the smart sensor and trigger an alarm event and/or notification or pre-event detection alert in response to the sensor data. A door controller may be configured to send different pulses or messages to indicate the type of alarm event to an alarm management server and/or access control servers via public/private cloud.

A motion sensor such as an accelerometer can be provided in wireless earbuds and/or the charging case for the earbuds. A wireless earbud can be placed on a table or floor and can remotely trigger an alarm if the accelerometer detects footsteps or disturbances nearby. This is useful for physical security in a hotel room or food establishment and can also generate an alert when the owner's attention is occupied in XR or is focused in a computer game.

Techniques and systems are described for creating and operating a vibration triangulation network. The network can include vibration sensor devices placed in a building, such as a store or a house, which are able to pinpoint the location of a target, e.g., person, animal, etc., through triangulation. A described technique includes receiving vibration notifications from vibration sensor devices, determining a location of a target within the building based on at least a portion of the vibration notifications and a vibration sensor map associated with the building, and triggering an alarm event based on a detection of the target.

In one implementation, a method for using a mobile computing device as a security system component includes receiving, from a mobile device and by a security system gateway, mobile device sensor information associated with sensor data captured by the mobile device at a premises monitored by the security system gateway; identifying, based on the received sensor information, a mobile device sensor information rule; identifying an action to perform in the mobile device sensor information rule; and automatically performing the identified action, by the security system gateway, in response to receiving the sensor information from the mobile device.

A Wireless Slide Fence utilizing signal reflection technology to detect rockslides and can determine the size and location of fallen rocks/objects impeding travel along a train track is presented. The present disclosure solves the technological problem of determining rock size and location to validate rockslide/fall alarms to reduce false alarms, while minimizing repairs required by conventional systems through the use of obstacle detection units and vital logic controllers. The present disclosure improves the performance of the system by, generating validated alarms when fallen rocks/objects satisfy the size criteria and are located in an area hazardous to train operations. In one exemplary embodiment, a loitering time can be implemented to validate object detections to reduce false positives due to transient objects such as migrating animals.

The present invention relates to a forward acoustic scattering based double-transmitter and double-receiver networking target detection system and method thereof. Two transmitting ends and two receiving ends are adopted, anchored at a sea bottom, and arranged in a parallelogram layout. Time of a target crossing transmitting-receiving connection lines is extracted by adopting a proper direct wave suppression method; and unknown parameters of the horizontal distance, the target velocity and the included angle between the target track and the transmitting-receiving connection lines are estimated at corresponding moving time intervals when the target crosses the four transmitting-receiving connection lines according to different crossing modes. An arrangement mode is simple and flexible, and monitoring of sea areas and sea channels can be realized. The information of the time of the target crossing the transmitting-receiving connection lines, extracted by the method, is more accurate and reliable.

A system and method may detect one or more shooting sounds and provide guidance to one or more evacuating people when an active shooting event has occurred indoors, thereby minimizing a secondary damage. The system comprises: a plurality of stations configured to detect one or more shooting sounds and transmit detection of the one or more shooting sounds; and a response server configured to receive the detection of one or more shooting sounds over a communication network, to generate action commands, respectively corresponding to each of the stations, based on the detection of the one or more shooting sounds, and to transmit the respective action commands to the each of the corresponding stations over the communication network.
