The disclosure relates to method and system for detecting and notifying actionable events during surveillance. The method may include receiving initial multi-modal inputs from a geo-location during surveillance, determining an incident of interest based on an analysis of the initial multi-modal inputs, and collecting additional multi-modal inputs from at least one access device corresponding to at least one person in the geo-location upon determination of the incident of interest. The method may further include determining the actionable event based on an analysis of the initial and the additional multi-modal inputs, and providing a notification of the actionable event to one or more appropriate authorities.

A smoke detector and a chamber are provided. The chamber includes a bottom plate, top plate, a plurality of baffle ribs disposed between the bottom plate and top plate, a transmitter base disposed between the bottom plate and top plate, and a receiver base disposed between the bottom plate and top plate. The receiver base is arranged apart from the transmitter base, and a center point of the chamber, being taken as an apex, the receiver base, and the transmitter base jointly define an angle being in a range of 45 degrees to 65 degrees.

An integrated fire and emergency management system comprised of standard emergency devices wherein each device is equipped with a sensing device configured for detecting and reporting to a server, by way of a transceiver, to a Central Management Software which connects to the Internet and all manner of private networks. The devices include alarm bells, extinguishers, manual alarm stations, battery-backed emergency lights which also comprise infrared, smoke, and motion detectors, sprinklers from a sprinkler system, smoke detectors (6 in 1), a display screen for displaying evacuation instructions, and light strips along the walls to indicate the best exit route. The 6-in-1 smoke detectors send their readings to the server where the Central Management Software has an algorithm that determines the best evacuation route that minimizes exposure to smoke and noxious gases.

A smart home solution can help reduce fires in the home, such as in the kitchen, by permitting a user to see, on a portable electronic device, whether a stove was left on or if there is an unexpected elevated temperature on the kitchen stove. Such an unexpected elevated temperature may be detected if the stove if left on without a pan on the stove, if the contents of a pan has boiled out of a pan, or if the stove is on at certain hours of the day, such as at night. The solution can include motion detectors, audible alerts, voice alerts and optional shutdown mechanisms to remotely turn off a stove. The system can include further options, such as built in fire extinguishing materials, arm and disarm features, various mounting capabilities and the ability to interact with a digital assistant, such as Google Home, Alexa, or the like.

Use of multiple sensors to determine whether motion of an object is occurring in an area is described. In one aspect, an infrared (IR) sensor can be supplemented with a radar sensor to determine whether the determined motion of an object is not a false positive.

A device for detecting a hazardous condition in an area includes a housing defining a chamber. There is at least one smoke sensing device for detecting the presence of smoke in the chamber. An extremely-high frequency detector includes at least one extremely-high frequency transmitter positioned relative to at least one extremely-high frequency receiver.

Disclosed is an electronic device comprising: a communication circuit, at least one sensor for sensing an open-or-closed state of a door and a person near the door, a processor electrically connected to the communication circuit and the at least one sensor, and a memory electrically connected to the processor.

Adjusting communication channels used by camera to communicate with a base station are described. In one aspect, characteristics of communication channels can be determined and the operation of the camera can be adjusted to use a communication channel based on a comparison of the characteristics of multiple communication channels.

A point detector (1) for a fire alarm system. The point detector (1) includes a fan (2) configured to aspirate air from a surrounding environment; and an inlet (3) in flow communication with the fan (2); the inlet (3) is configured to split the incoming flow into multiple streams (4); and each stream (4) of the multiple streams (4) is configured to be in flow communication with a respective sensing device (6).

A device for detecting a hazardous condition in an area includes a housing defining a chamber. There is at least one smoke sensing device for detecting the presence of smoke in the chamber. An extremely-high frequency detector includes at least one extremely-high frequency transmitter positioned relative to at least one extremely-high frequency receiver.
