A shock detector device (110) for premises security is described. The shock detector device (110) comprises a shock detector sensor (112) configured to sense physical motion and to output an electrical signal in response to the physical motion. Processing circuitry (114) is configured to process the electrical signal by: obtaining an indication that a shock event has occurred if a value for at least one parameter of the electrical signal is determined to exceed a threshold value; and processing instructions for adjusting at least one detection parameter of the shock detector device (110) in response to a determination that the shock event is a false alarm event, wherein the adjusting of the at least one detection parameter results in a decrease of a sensitivity of shock detection by the shock detector device (110).

A building monitoring system includes a first sensor configured to detect a first condition in the space, a second sensor configured to detect a second condition in the space, and a robotic sentinel. The robotic sentinel includes a memory for storing one or more rules each configured to identify an alert condition for the space based on the first and/or second conditions in the space, a communications module configured to communicate with a remote device over a network, and a controller operatively coupled to the sensors, the memory, and the communications module. The controller is configured to apply the one or more rules to the first and second detected conditions in the space to identify one or more alert conditions and determine what action is required by the robotic sentinel, and if action is required, command the robotic sentinel to travel to a location of the alert condition.

An intrusion detection apparatus and method thereof are provided. The intrusion detection apparatus includes a status detection device, a front-end signal processor, a delay device, and a signal sampler. The status detection device is configured to generate an indicating signal according to an opened status of the case. The front-end signal processor receives the indicating signal and performs a noise filtering function on the indicating signal so as to generate a processed indicating signal. The delay device delays the processed indicating signal to generate a delayed indicating signal. The signal sampler samples the processed indicating signal to generate a detection result according to the delayed indicating signal.

The present disclosure relates to aspirating smoke detectors (ASD). In an ASD, ambient air is aspirated and is fed to a fire detector unit for determining a signal level. For normal operation, the suction power is set to a nominal airflow value and this is increased from a minimum signal level value in order to shorten the transport time of aspirated smoke through the suction pipe to the fire detector unit. In some embodiments, an interruption signal provided for normal operation is output if the airflow exceeds an upper limit value for a minimum period. Independently thereof, the suction power is increased from the minimum signal level value only to the extent that the airflow does not exceed the upper limit value. Or, regardless thereof, the suction power is increased only for a timespan smaller than the minimum period in which the airflow exceeds the upper limit value.

According to one aspect of a technique the present disclosure, there is provided a processing apparatus including: an apparatus controller including a memory storing apparatus data containing monitor data containing sensor information and an alarm indicating a failure detected based on the sensor information and an alarm analysis table containing analysis items. The apparatus controller is capable of outputting the alarm containing an alarm ID for specifying a type and an occurrence time of the alarm; specifying candidates of the analysis items from the alarm ID; acquiring monitor data corresponding to the candidates; determining a rank of the cause of the alarm according to a difference between monitor data at the occurrence time and a predetermined threshold value; and displaying a relationship between the monitor data and the threshold value. The display screen displays an occurrence history of the alarm and history of acquiring the monitor data.

A portable alarm system has a base unit including a processor electrically connected to a wireless transceiver configured to communicate wireless signals to an external location. The base unit is further configured to receive wireless alarm signals from at least a first sensor and a second sensor, both of the first and second sensors being physically separated from the base unit. The processor is configured to be selectively programmed by a user to cause the base unit to communicate with a remote monitoring station in response to receiving an alarm signal from the first sensor, but not in response to receiving an alarm signal from the second sensor. Instead, when an alarm signal is received from the second sensor, the processor causes a different action, other than communicating with the monitoring station, to occur. Such action can include, for example, sending a wireless communication to a mobile electronic device.

Devices, systems, and methods for self-testing event devices of a building alarm system are described herein. One self-test alarm system device having a self-testing capability includes a first independent power source connected to a detector module and a second independent power source connected to a self-test module.
