An LED security light includes an LED load and a motion sensor. The LED load is activated at dusk and deactivated at dawn by a light sensing control unit. At night, the LED load is activated for performing a low level illumination. When a motion signal is detected by the motion sensor, the LED load is switched to perform a high level illumination for a short time period and then resumes to the low level illumination. The low level illumination and the high level illumination are respectively adjustable within respective designed ranges. The LED load is driven by a switching circuitry comprising a driver to output an adequate voltage with constant electric current such that a voltage V across each LED is confined in a range V.sub.th<V<V.sub.max with V.sub.th being a threshold voltage and V.sub.max being a maximum voltage avoiding damaging the LED.

A method for reducing alarm notifications from a security system deploying a plurality of cameras within a monitored area includes processing a first video stream captured by the first camera of the security system to detect an alarm event observed in the Field of View (FOV) of the first camera and processing a second video stream captured by a second camera of the security system to detect the same alarm event observed in the FOV of the second camera. A combined alarm notification corresponding to the alarm event is sent, wherein the combined alarm notification includes the alarm event and may identify the first camera and the second camera as both detecting the same alarm event in their respective FOVs.

A module for detecting the angular position of the drive shaft of a valve includes a printed circuit proximate a drive shaft of a valve body, or of an extension element thereof or a motor shaft of a valve actuator. The module also includes a magnet(s) fastened to the drive shaft, a magnetic sensor(s) supported on the printed circuit, and a communication interface. The magnetic sensor(s) generate an electrical signal indicating the position of the magnet(s). The communication interface remotely transmits a corresponding reading. The acquisition of the reading can be carried out at pre-set time intervals, which can be managed according to the requirements of the production process. The detection module is free of wired connections with the outside. A valve and an adapter element are also provided with the module, and a method for detecting the open state of the valve remotely by the module.

Motion detectors can include a housing defining a first cavity and an aperture extending through the housing. A circuit board can be disposed in the first cavity.
