A light and motion detection sensor includes a light-emitting diode (LED) indicator configured to provide intermittent light from the LED indicating that the light and motion detection sensor is operating, a photocell sensor configured to detect ambient light, a passive infrared (PIR) sensor having a lens and configured to detect infrared radiation, and a sensor retainer configured to retain the light and motion detection sensor in a mounting, transmit ambient light to the photocell sensor, and transmit the intermittent light from the LED indicator such that the intermittent light from the LED indicator is visible from the sensor retainer.

Radio wave information is observed in a predetermined environment. Information related to the radio wave is compared to new radio wave information. In a case where a result of the comparison satisfies a predetermined condition, a user is provided with a predetermined function. In an embodiment, positional information showing a position where the radio wave information is acquired and a time stamp is recorded for comparison, and in a case where the newly acquired radio wave information is radio wave information corresponding to a suspicious-person, a warning is issued to a user. In an embodiment, in a case where predetermined pieces of home radio wave information are not detected within a predetermined period, a system is operated to manage a house.

A system and method for an optical displacement detector system with adjustable pattern direction are disclosed. In an embodiment, the detector system includes a mounting bracket and a sensor assembly. The sensor assembly includes a housing, and a sensor module in the housing. The sensor assembly can be rotated with respect to the mounting bracket to adjust an optical axis of the sensor module. In another embodiment, the detector system includes a turntable that enables additional adjustment of the optical axis. Such a system significantly improves installation of these detector systems as compared to existing optical displacement detector systems, which have fixed optical axes. In one application, the detector system is installed in a door system having a door and door frame, and detects displacement of the door.

The present disclosure provides microwave intrusion detecting device with multi-direction and multi-range fence which detects human or vehicle intrusions within altering range by transmitting microwave signals and receiving echo signals. It includes pair of detecting units, a signal unit, a processor, a control interface, an alarm unit, a storage unit, a communication unit, and a power supply unit. The pair of detection units are physically composed back-to-back which can form a long-distance electronic fence. The second detection unit can be separated from a main body to adjust the antenna coverage angle to adapt to environment or obstacles. The signal unit generates the frequency modulated continuous wave signal to the two detecting units respectively. The processor can set thresholds segments to from passing gates in microwave intrusion detecting device and can generate an alarm unit message.

A process for dynamic vehicular perimeter threat detection includes first identifying a vehicle destination location. Vehicular perimeter contextual parameters including an incident type, a historical crime rate, or a real-time crime rate associated with the vehicle destination location are retrieved. A perimeter distance of a sized vehicular geofence surrounding the vehicle is modified as a function of the vehicular perimeter contextual parameters. A 360 degree vehicular light imaging or radio wave distancing system physically coupled to the vehicle detects a breach of the sized vehicular geofence. One or more target electronic devices to notify of the detected breach are identified. And a notice of breach message provided to the identified one or more target electronic devices.
