A vehicle includes determines that a vehicle alarm system has been engaged and determines a local context applicable to the vehicle alarm system. The vehicle obtains an alarm system configuration mapping applicable in light of the local context. The vehicle changes sensitivity of one or more sensors associated with the alarm system based on the configuration mapping.

A corrective PIR sensor system includes a PIR sensor circuit with a PIR sensor for controlling and electrical load circuit in response to occupancy detection. The PIR sensor is couples to an auxiliary sensor for measuring or monitoring one or more environmental condition. The corrective PIR sensor system also has a computing device connected to the PIR sensor and the auxiliary sensor for running corrective intelligent software or firm-wear to reduce false triggers of the PIR sensor circuit based on the environmental condition measured or monitored by the auxiliary sensor.

Disclosed is an alarm device for detecting a hazard in a control zone, the alarm device having: a hazard sensor that comprises a configurable sensitivity level and a device controller that controls the sensitivity level of the hazard sensor, wherein the alarm device: receives over an electronic network a target sensitivity, and calibrates the hazard sensor to achieve the target sensitivity level.

An intelligent audible device is provided that is constructed to monitor for an event, such as actual or elapse time, or a sensor exceeding a threshold. Responsive to the event, a sound input transducer is activated, and an output sound signal representing an intended message is projected into the local environment by a sound output transducer. The sound input transducer captures the actual sound projected into the local environment. The captured actual sound is processed and compared to the output sound signal. In this way it may be confidently determined if the intended message was actually properly projected into the local environment.

An image enhancement method for video analysis or automatic video surveillance systems has at least one image acquisition device, through which an IR thermal spectrum image is captured from an area of space, a scene calibration system and a detection system, through which at least one object type is detected. The method includes at least one processing stage in which the contrast of the captured image is enhanced by the image acquisition device through the image's depth or scene information obtained directly or indirectly by the scene calibration system or entered manually by the user.

A motion sensor includes a sensor element to sense a motion, and a controller communicably coupled to the sensor element. The controller is configured to set a detection sensitivity of the motion sensor to a maximum setting of the detection sensitivity. The controller is further configured to decrease the detection sensitivity of the motion sensor upon a detection of the motion until the motion is undetectable by the motion sensor at a decreased setting of the detection sensitivity. The controller is further configured to increase the detection sensitivity of the motion sensor until the motion sensor detects the motion at an increased setting of the detection sensitivity and to set the detection sensitivity of the motion sensor to a new setting based on the increased setting.
