A control panel is used to monitor events within a security system or other automation system. In the event an intruder enters a physical location, the intruder may attempt to damage the control panel to disrupt its operation. One or more sensors of the control panel may detect disruption in the operation of the control panel. Example sensors may detect an impact force, sudden acceleration, removal from a mounted location, or disruption of communication with an input/output element, such as a display device. When an event is detected at the control panel itself, the control panel can send a signal to a remote service provider, and the remote service provider can follow-up with the customer. The control panel and/or remote service provider may also determine when the control panel loses partial or complete power loss to identify the disruption as a potential crash-and-smash entry.

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).

Provided is a safety scanner that enables simplification of an operation of checking an operating state. The safety scanner includes a scan image generation section that generates a scan image that includes a plurality of sets of distance measurement information obtained by performing scanning with a detection light emitted by an emitter, the plurality of sets of distance measurement information being represented as a plurality of distance measurement positions on a scanning plane of the detection light, and a monitoring image display that displays the scan image on a screen.

Provided is a safety scanner capable of easily grasping the correspondence relationship between a distance measurement position on a scanning plane and a real space. The safety scanner includes a distance measurement section that obtains distance measurement information corresponding to a distance optically sensed and a scanning angle of a detection light, an intrusion sensing section that senses an intruder within the protection area on the basis of the distance measurement information and a area designation information, a marker identification section that identifies a marker movably disposed within the detection area, and the distance measurement information of the marker as an area generation information for determining the protection area.

Provided is a safety scanner capable of obtaining uniform optical performance for a view angle of 180° or more. The safety scanner includes an optical rotator that emits detection light from a light source to a detection area and causes the detection light to perform scanning in a circumferential direction, a light receiving element that receives reflected light from an object within the detection area through the optical rotator, a casing that houses the light receiving element. The casing includes a canopy part, a bottom part facing the canopy part, and a coupling part that couples a rear end of the canopy part to a rear end of the bottom part. The protective cover includes a window formed in a circular arc shape, corresponding to an optical path of the detection light and the reflected light, having a central angle larger than 180° with respect to the rotation axis.

Provided is an optical safety system that enables simplification of an editing operation for area designation information. A safety scanner includes an intrusion sensing section that determines the presence or absence of an intruder into a protection area. The setting support device includes a pseudo determination information generation section that determines a presence or absence of an intruder into a protection area on the basis of an area designation information before being transmitted to the safety scanner and a distance measurement information received from the safety scanner and generates a pseudo determination information indicating the determination result.

A security monitoring system includes at least one sensor configured to sense an event condition. A security monitoring system controller communicates with the sensor and an indicator of alarm and trouble conditions. The central security system also detects barometric pressure within a monitored area. The security system controller is configured to receive an event signal indicative of an event from the at least one of the sensors and receive an indication of the barometric pressure from a barometer. When the barometric pressure from the barometer indicates a change in barometric pressure, the security monitoring system controller confirms that the event is present and outputs an indication signal to the indicator based on the confirmed event. When the barometric pressure from the barometer does not indicate a change in barometric pressure, the security monitoring system controller suppresses the output of the indication signal.

A system for providing information about presence in a space includes a movement sensor for generating a signal upon detecting movement; and a presence sensor for generating a signal upon detecting presence, being a temperature-based matrix sensor having an array of sensing elements.
The system further includes a processing and/or control component in communication with the movement and presence sensors, configured to generate a presence signal upon receiving the first and/or second signals; and configured to obtain background information of the presence detection field. The information includes reference temperature values and are obtained upon the movement sensor not detecting movement and/or the presence sensor detecting presence. For each sensing element with presence, using the measured temperature value of surrounding sensing elements not having presence. If all surrounding sensing elements have presence, using the measured temperature value of some sensing elements surrounding the former surrounding sensing elements not having presence.

Provided are an acoustic sensor and a home appliance system comprising the same. The acoustic sensor comprises a communication unit, a microphone to collect an acoustic signal, a memory to store a failure acoustic signal of a home appliance, and a processor, wherein in response to the acoustic signal, collected by the microphone, corresponding to the failure acoustic signal of the home appliance, the processor transmits the collected acoustic signal, or data corresponding to the collected acoustic signal, to an external server or a terminal. Accordingly, failure of the home appliance may be easily diagnosed.

Methods and systems, including computer programs encoded on computer storage media, for providing an indication of a direction a person passes through a door in a property, the method including receiving, at a sensing device and from a control panel of an alarm system in a property, instructions to provide an indication of a direction a person passes through a door in the property; obtaining motion data using a motion sensor that is included in the sensing device; detecting the opening of the door using a magnetometer included in the sensing device; based on the obtained motion data and detected opening of the door, determining a direction a person passed through the door; and providing, to the control panel, an indication of the direction the person passed through the door.
