A security device is disclosed comprising a main housing, a power supply housing releasable from the main housing and a release arrangement configured to provide a release process in which the power supply housing is moveable from an installed configuration to a released configuration via a partially released configuration. A power connection is provided for supply of power to the security device when the power supply housing is in the partially released configuration. Processing circuitry is configured to obtain power via the power connection and receive an indication that the power supply housing has moved from the installed configuration and/or to the partially released configuration.

A position sensing system and method for detecting the displacement of a door from a reference position, such as, for example, from a closed position. The system includes a magnetometer that may be operably connected to the door, and which measures positional location relative to a reference magnetic field, such as, for example, a magnetic field provided by a magnet of a lock device. The system may also include an accelerometer that detects acceleration of the door, and thereby provides an indication of when location is to be measured by the magnetometer. Measurement information from the magnetometer is used to derive a position indicator that is compared to a reference indicator, the reference indicator being associated with the reference position. Differences between the position and reference indicators may provide an indication that the door has been moved from the reference position.

A motion detector that can automatically adjust a dwell time used by the motion detector to prevent unnecessary transmissions as an activity level of an area increases or decreases. The motion detector determines the activity level in the area and if the activity level is increasing, the dwell time is reduced and vice-versa.

Methods and systems for managing a premises are disclosed. The premises may comprise a premises management device. The premises management device may be in communication with a security system. The premises management device may manage consumption by maintaining or disabling components associated with the premise management device.

A gateway of a surveillance system, the gateway includes: a communication module configured to communicate with a plurality of network cameras including a first network camera and a second network camera; and a processor configured to recognize a motion of a subject based on event information transmitted by the first network camera and to transmit subject information generated based on the motion of the subject to the second network camera.

In a system and method for detecting carbon dioxide in an enclosed volume, a CO2 detection system is triggered to awaken from a deep sleep state. Once awake, the system queries system sensors to determine the current system parameters, including current CO2 level and temperature. Current and expected CO2 decay rates are calculated, and the system determines whether the current CO2 decay rate is within an expected normal range for an unoccupied enclosed volume. If the volume is static, i.e., not moving, and the CO2 rate is rising and the temperature is rising, a series of alerts are sent to contacts previously set up by the user. If the alerts are not cleared by a user, emergency management personnel are notified.

Systems and methods for ground fault circuit interrupter trip detection and entire premises loss of power and restoration detection and notification of those events is disclosed. An example system may receive a smart plug identification. The system may authorize a smart plug. The system may link the smart plug to a smart plug application. The system may query the smart plug to obtain a power notification. The system may notify smart plug application of a power status.

The present disclosure relates to a method and system for controlling a smart device. The method may include obtaining correlating information of the smart device. The correlating information may include at least one of smart device information or a communication status of the smart device. The method may include determining indication information of the smart device by processing the correlating information of the smart device according to a preset algorithm. The method may include performing designated operations related to the smart device based at least in part on the indication information.

A method for predictive analysis for maintaining a battery charge of a personal monitoring device is provided. The method includes: locking the personal monitoring device to a limb of a monitored person; collecting historical information about the personal monitoring device including movement data of the personal monitoring device and battery charging history of the personal monitoring device; analyzing the collected historical information for patterns of battery charging behavior; receiving a current location of the personal monitoring device; determining whether to send a battery charge reminder to the monitored person, based on at least a current location of the personal monitoring device, a current batter charge, and the patterns of battery charging behavior; and providing, in response to a positive outcome of the determining, a notification to the monitored person to charge the battery.

An intrusion detection apparatus and method thereof are provided. The intrusion detection apparatus includes a status detection device, a front-end signal processor, a delay device, and a signal sampler. The status detection device is configured to generate an indicating signal according to an opened status of the case. The front-end signal processor receives the indicating signal and performs a noise filtering function on the indicating signal so as to generate a processed indicating signal. The delay device delays the processed indicating signal to generate a delayed indicating signal. The signal sampler samples the processed indicating signal to generate a detection result according to the delayed indicating signal.
