Methods, systems, and apparatus, including computer programs encoded on computer storage media, for reduction of false detections using an ultrasound emitter. One of the methods includes obtaining sensor data captured by a sensor of a property monitoring system; detecting an object represented by the sensor data; determining that the object represented by the sensor data is likely a non-object of interest and being detected as an object of interest; and in response to determining that the object represented by the sensor data is likely the non-object of interest and being detected as the object of interest, sending, to an ultrasound emitter, a command to cause the ultrasound emitter to emit ultrasonic sound around the sensor.

A barrier alarm device for reducing the number of false alarms that may occur in a home security system. In one embodiment, a barrier alarm device, such as a door or window sensor, determines whether a barrier, such as a door or a window, has been opened, determines whether a human being is in proximity to the door or window inside a monitored premises. If a human being is inside the monitored premises when the door or window is opened, it indicates that the human being is authorized to be inside the monitored premises, and an alarm signal is not transmitted to a central security panel, thus reducing false alarms.

A barrier alarm device for reducing the number of false alarms that may occur in a home or business security system. In one embodiment, a barrier alarm device, such as a door or window sensor, determines whether a barrier, such as a door or a window, has been opened, and determines whether a human being is inside a premises in proximity to the door or window. If a human being is inside the monitored premises when the door or window is opened, it indicates that the human being is authorized to be inside the monitored premises, and the barrier alarm device transmits a timed alarm signal to a central security panel, causing a security response to be generated by the central security panel if a predetermined time period elapses without a user canceling the security response.

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 surveillance apparatus for determining a position of an object in a field of view, comprising a radar sensor having at least on transmitting antenna configured to transmit electromagnetic radiation and a plurality of receiving antennas configured to receive electromagnetic radiation, wherein the receiving antennas form a virtual antenna array, and a processing unit connected to the radar sensor to receive signals from the receiving antennas corresponding to the received electromagnetic radiation, wherein the processing unit is configured to determine a correlation matrix on the basis of the received signals, and wherein the processing unit is configured to determine a direction of a position of the object in the field of view with respect to the radar sensor on the basis of the correlation matrix for a defined distance of the object from the radar sensor.

Devices, non-transitory computer-readable media and methods for providing a haptic signal based upon a detection of an object are disclosed. For example, the processor of a device may transmit a first ultrasonic signal via an ultrasonic emitter and detect an object based upon a receiving of a reflected signal via an ultrasonic detector, where the reflected signal comprises a reflection of the first ultrasonic signal from the object. The processor may further monitor for a second ultrasonic signal via the ultrasonic detector. The device may be associated with a user, and the second ultrasonic signal may be associated with a teammate of the user. The processor may also select whether to provide an instruction to a haptic actuator when the object is detected, based upon whether the second ultrasonic signal is received via the ultrasonic detector.

System and method for observing the presence, location, movement and/or attitude of one or more objects to be monitored with a monitoring system, wherein sensors of the system are disposed in a part, such as on a floor, wall or ceiling, of the area to be monitored, and the system measures with sensors the area to be monitored, and determines the presence, location, movement and/or attitude of the object on the basis of the measurement results of the sensors. The system has a first mode and a second mode, and the system checks in the first mode the attitude and/or state of health of the object in the area to be monitored and functions in the second mode as an intruder alarm monitoring the area to be monitored.

In at least one embodiment, a computer-program product embodied in a non-transitory computer readable medium that is programmed to provide an alert for a user of an environment outside of the user's visual field of view is provided. The computer-program product includes instructions to receive an echo profile indicative of at least one object outside of the user's visual field of view from headphones and to receive a command indicative of at least one object to detect on the echo profile from the user. The computer-program product includes instructions to generate an alert for the user to notify the user of a detected object in the user's visual field of view in the event the echo profile includes the at least one object.
