Multispectral imaging and related techniques are provided to detect thermal and non-thermal anomalies at reduced false detection rates. A multispectral imaging system includes an infrared light imaging sensor that captures infrared image data in a first spectral band, of a scene and an ultraviolet light imaging sensor that captures ultraviolet image data in a second spectral band, of the scene. The system also includes a processor that combines the ultraviolet image data and the infrared image data to generate composite image data, determines a ratio of a first radiant intensity in the first spectral band to a second radiant intensity in the second spectral band, from the composite image data, and determines whether the ratio corresponds to a predetermined radiant intensity ratio of a known thermal or electrical anomaly. The processor can detect the thermal or electrical anomaly when the determined ratio corresponds to the predetermined radiant intensity ratio.

A cloud server (104) receives environmental information of respective installation sites of a plurality of appliances (101a, 101b, 101c, 102a, 102b) via a network (1000), and determines one or more appliances that are installed in a same room among the plurality of appliances (101a, 101b, 101c, 102a, 102b), based on the received environmental information.

A monitoring system that is configured to monitor a property is disclosed. The monitoring system includes a thermal camera that is configured to generate a thermal image of the property. The monitoring system further includes a monitor control unit that is configured to receive, from the thermal camera, the thermal image. The monitor control unit is further configured to, based on the thermal image, determine a temperature of a portion of the property depicted in the thermal image. The monitor control unit is further configured to determine that the temperature of the portion of the property depicted in the thermal image satisfies a temperature threshold. The monitor control unit is further configured to, based on determining that the temperature of the portion of the property depicted in the thermal image satisfies the temperature threshold, select and perform a monitoring system action.

A method for monitoring a dangerous situation in a space based on a frequency response pattern according to an embodiment includes loading, by a processing unit of a mobile terminal located in the arbitrary space, a setting value corresponding to an operational mode selected through control software installed on the mobile terminal, controlling, by the processing unit, a speaker of the mobile terminal to generate a frequency corresponding to the loaded setting value, receiving the frequency which was generated in the controlling and reflected in the space through a microphone of the mobile terminal, determining, by the processing unit, whether the dangerous situation occurred in the space by comparing the frequency response pattern with a preset reference value, and taking, by the processing unit, a follow-up action when it is determined that the dangerous situation occurred in the space by the determining.

A fire detection device includes a vented detector housing, with an opening defined in a mounting base. A substance exhaust channel in air flow communication with the opening extends upward from the mounting base. A pressure release turbine includes an impeller operatively disposed in the channel. A rotation sensor senses rotation of the impeller and generates an alert upon detection of a heat level indicated by rotation of the turbine rotor at a predetermined speed. A high pressure and/or heat louver disposed over the opening opens in response to a predetermined heat level. An actuator detects opening of the louver and generates an alert. A thermostatic device disposed in the housing senses, and generates an alert at, a predetermined heat level. A thermal imaging device disposed in the housing senses, and generates an alert at, a predetermined heat level.
