The disclosure is a connectivity APP loaded in a mobile phone for configuring a linkable security lighting system comprising a plurality of LED security lights installed outdoors, wherein by operating the connectivity APP the plurality of LED security lights are divided into N groups of member security lights to be linked. Each group of member security lights is assigned a group code to be applied to each member security light in the group such that within the group the member security lights are interlinked wirelessly via wireless signals prefixed with the same group code, wherein when a member security light is initiated by a sensing signal for operating an illumination mode, the member security light being initiated acts as a commander to transmit an instruction signal to activate all member security lights belonging to the same group code to synchronously operate the illumination mode.

An example intrusion detection system for a computer includes: an ambient light sensor to detect an increase in ambient light indicative of a housing of the computer being opened; and a super input/output integrated circuit (SIO) to receive a signal from the ambient light sensor indicating that the housing of the computer has been opened.

The present application relates to the field of logistics, discloses an anti-disassembly logistics appliance and anti-disassembly method therefor, realizing the anti-disassembly alarm of a designated module under the premise of simple structure and low power consumption. An anti-disassembly logistics appliance, comprising: a confined space and an anti-disassembly module disposed in the confined space; the anti-disassembly module comprises: one or more photoelectric devices, a wireless communication unit and a determining unit; the determining unit is configured to determine whether an electrical signal output by the photoelectric device is greater than a preset threshold, and if so, triggers the wireless communication unit to transmit an alarm signal; the structure of the confined space satisfies following requirements: the confined space is an light-tight dark space after the anti-disassembly module is installed; during the process of disassembling the anti-disassembly module from the logistics appliance, the light-tightness of the confined space is at least temporarily destroyed to enable the optoelectronic device to detect light.

A smoke detector system 20 is disclosed, including a beam detector unit 10 having a moveable portion 14 comprising at least one light transmitter 16, a base portion for fixing to a surface, and a motor configured to rotate the moveable portion 14 relative to the base portion. The system also has at least one receiver for detecting light transmitted by the transmitter.

A poaching detection apparatus includes a frame member with first and second reflectors mounted thereto. The reflectors mimic the reflective qualities of the eyes of certain animals; accordingly, the reflectors will appear to be animal eyes when a poacher shines a portably light on them. The poaching detection apparatus also includes at least one light sensor that, when struck by the light from a poacher using a “spotlighting” technique, causes the activation of at least one alarm and/or alert to deter the poacher and/or notify property owners or authorities of the presence of poachers

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.

The system also has at least one receiver for detecting light transmitted by the transmitter.

A system for monitoring a petrochemical installation is disclosed. The system can include an optical imaging system comprising an array of optical detectors. The system can comprise processing electronics configured to process image data detected by the optical imaging system. The processing electronics can be configured to detect a target species based at least in part on the processed image data. The processing electronics can further be configured to, based on a detected amount of the target species, transmit an alarm notification to an external computing device over a communications network indicating that the target species has been detected at the petrochemical installation.

A video-based security system for providing video security to cargo transport vehicle. The security system includes a camera support configured at the exterior of a cargo storage area; a camera system attached to the camera support for covering a top plane, front plane, left plane, right plane, and back plane of a cargo area; and a main unit connecting to the camera system for logging incident records.

An LED security light includes a light emitting unit, at least one sensing unit, a loading and power control unit and a power supply unit configured with a first power source and a second power source, wherein a power level detector and a power switching circuitry are installed to select and connect at least one of the first power source and the second power source to the light emitting unit. The light emitting unit is activated at dusk and is deactivated at dawn. When the first power source is used, the LED security light generates a first level illumination. When the second power source is used, the LED security light generates a second level illumination. The first power source is a solar power while the second power source is a backup battery.
