The present technology relates to an information terminal, an information processing device, and a program that make it possible to find out that an installation status has changed. The information terminal transmits information at predetermined time intervals. The information terminal causes information that is to be transmitted in a normal state of installation to be transmitted in a case where, after a return from a sleep state, a flag indicating whether or not an abnormal state of the installation has been detected indicates that the abnormal state has not been detected, and causes information different from the information that is to be transmitted in the normal state to be transmitted in a case where, after the return from the sleep state, the flag indicates that the abnormal state has been detected. The present technology can be applied to a home communication system.

A device includes a housing, a tamper switch supported at the housing, and a tamper actuator receivable at the housing. The tamper actuator is movable between a tamper disabled position and a tamper enabled position. In the tamper disabled position, the tamper actuator is fixed in place at the housing. In the tamper enabled position, the tamper actuator is configured to move relative to the housing between a tamper switch engaged position and a tamper switch released position.

Image surveillance and reporting technology, in which an event that is indicative of potential physical activity within an area corresponding to a location of a camera unit is detected. In response to detection of the event, the camera unit is controlled to capture one or more images of the area corresponding to the location of the camera unit. The one or more images captured by the camera unit are analyzed to determine whether the one or more images include image data that is indicative of relevant physical activity within the area corresponding to the location of the camera unit. The one or more images are handled based on the determination of whether the one or more images include image data that is indicative of relevant physical activity within the area corresponding to the location of the camera unit.

Techniques are described for handling an event where a control panel or an alarm signaling device is tampered with or destroyed by a disablement tactic, e.g., a “crash and smash intrusion.”

An alarm management system of the present disclosure includes an alarm management apparatus, a monitoring terminal, and a controller. The alarm management apparatus generates an alarm based on information received from the controller or receives an alarm from the controller, receives information related to a filtering condition from the monitoring terminal, performs filtering on the alarm based on the filtering condition, and presents the alarm subjected to the filtering to an operator via the monitoring terminal.

Various systems, methods, and/or devices are discussed for diagnosing monitoring system equipment functionality. In some cases methods are discussed that include, inter alia, receiving test results and sending test commands to/from monitor devices. The results are analyzed to determine an operation status. In various cases systems for determining operation status are discussed that include at least two monitor devices. The monitor devices are configured to execute test commands and to provide corresponding results. The results are analyzed to determine an operation status.

In accordance with one or more embodiments herein, a flame detecting arrangement 100 is provided. The flame detecting arrangement 100 comprises: at least one optical flame detector 110, arranged with its field-of-view covering a predetermined area; at least one movement sensor 120, arranged together with the at least one flame detector 110; and at least one processing device 180 arranged together with the at least one flame detector 110. The at least one processing device 180 is arranged to: receive signals from the movement sensor 120; detect abnormal movement of the flame detector 110 based on these signals; and alert an operator and/or a control system 200 if abnormal movement of the flame detector 110 has been detected. This enables the field-of-view of the flame detector to be corrected to the desired, preferably the original, field-of-view.

A fire detection system for monitoring a monitored environment includes a smoke detector configured to determine a concentration of smoke in a sample of air from the monitored environment; a gas sensor configured to determine a concentration of a predetermined gas in the sample of air, the predetermined gas is one of carbon monoxide, carbon dioxide, nitrogen dioxide and sulphur dioxide; and a control module in communication with the smoke detector and the gas sensor; the control module is configured to identify a source of the smoke based on the concentration of smoke and the concentration of the predetermined gas; and the source of the smoke is identified to be a non-fire source when the concentration of the predetermined gas in the sample of air is below a first threshold.

A method for detecting intrusions in a monitored volume in which: N tridimensional sensors acquire local point clouds in respective local coordinate systems, a central processing unit receives the acquired local point clouds and, for each sensor, computes updated tridimensional position and orientation of the sensor in a global coordinate system of the monitored volume by aligning a local point cloud acquired by said tridimensional sensor with a global tridimensional map of the monitored volume, and generates an aligned local point cloud on the basis of the updated tridimensional position and orientation of the sensor, the central processing unit monitors an intrusion in the monitored volume by comparing a free space of the aligned local point cloud with a free space of the global tridimensional map.
