A method includes: receiving IR radiation with a plurality of IR sensors; producing a plurality of output signals with the plurality of IR sensors based on the received IR radiation, where each of the plurality of output signals is indicative of an intensity of the IR radiation received by a respective IR sensor of the plurality of IR sensors; detecting an IR source based on the plurality of output signals; generating a candidate alarm in response to detecting the IR source; determining whether the detected IR source matches any reference IR source of a set of reference IR sources; when the detected IR source matches one reference IR source of the set of reference IR sources, issuing a user alarm, and when the detected IR source does not match any reference IR source of the set of reference IR sources, canceling the candidate alarm without issuing the user alarm.

An event detection unit (EDU) for detecting an explosive event is provided. The EDU includes different types of sensors for measuring characteristics of an explosive event. The EDU includes an event notification component. The EDU also includes a processor that receives a measurement from the sensors and generates a combined non-event probability and a combined event probability based on that measurement that indicates a likelihood that an explosive event has not occurred or has occurred. The processor determines whether an explosive event has occurred based on the non-event probabilities and event probabilities. When an explosive event has been determined to occur, the processor directs the event notification component to output a notification that an explosive event has occurred.

The present disclosure describes a system and method designed to protect the contents of a region or space within a facility (e.g., building, home, vehicle, outdoor space, etc.). The system is configured to identify an area to be protected (e.g., nightstand, medicine cabinet, safe), monitor surroundings, and manage and deploy response(s) to threats to the region or space under protection. The system may also be configured to provide incremental warnings, interventions, or countermeasures to deter people or animals from accessing the Protected Space.

A high security two-way virtual cross-barrier observation and communication device has a mounting frame with a hardened core, a pair of digital displays, and a pair of cameras. The mounting frame may correspond to a typical interior door of a building or a relevant component of a vehicle, aircraft, or other relevant application. The hardened core is bullet-resistant and fire-resistant to protect occupants of a protected space from harm. The digital displays and cameras are positioned on opposing sides of the mounting frame, each camera transmitting a live video feed to the opposing display, creating the appearance of a window while protecting occupants. The digital displays may be used to display any desired information. An emergency protocol may be activated to communicate with emergency services. A plurality of laminate layers bond and encapsulate the displays and cameras to the hardened core, forming a rugged, self-contained unit with no moving parts.

The present disclosure discloses an object detection method used in an object detection apparatus that includes the steps outlined below. An image signal received from an image sensor is detected to generate an image detection signal when an image variation is detected. An infrared signal received from an infrared sensor is detected to generate an infrared detection signal when an infrared energy variation is detected. A time counting process is initialized when the image detection signal is generated. An object detection signal is generated when the infrared detection signal is generated within a predetermined time period after the time counting process is initialized. A detection distance of the image sensor is larger than a detection distance of the infrared sensor.

A system (41) for activating an infrared light source is configured to receive input indicating human presence in a space, determine a type and/or probability of the human presence based on the input, decide whether to activate an infrared light source (12) or a visible-light light source (11) in the space based on the type and/or probability of the human presence, and activate the infrared light source or the visible-light light source in dependence on the decision.

A night security alarm system for a home, such as a recreational vehicle or a caravan, which night security alarm system includes: a first detector adapted to detect movement inside the home; a second detector adapted to detect opening of a door connecting the inside and the outside of the home; a third detector adapted to detect movement outside the home; and a control unit configured to automatically deactivate the night security alarm system if the first detector detects movement inside the home and then the second detector detects opening of the door and then the third detector detects movement outside the home.
