What is a sensor lamp of movement?

Motion sensor is a light -producing device that is activated in response to movement. Sometimes a lamp is used as a comfort lamp and turns on when it enters a commonly used room like a toilet. After activation, such a lamp generally remains active until a certain amount of time in which he did not find movement. Such lamps are commonly used to reduce electricity costs because they turn off automatically when people are not present rather than constantly active. The lamps activated by movement are also commonly used outdoors for guidance and for burglary.

In most cases, the motion sensor lamp operates by optical detection, which means that sudden changes in external or visual input generally start activation. Usually this does not include changes in visual light, because such devices are often used in places that are subject to complete darkness. Instead use lasers or infrared light; When a person or object passes into or via laser or infraredAlthough light, a lamp of movement is activated. Continued movement in the detection area causes light to remain active while stopping movement causes light to deactivate for a set time period.

To ensure that light is activated only if necessary, it is important that the sensor is well placed well and the activation area is well defined. If someone wants a lamp to be activated when someone approaches their front doors, they should also try to ensure that the light does not break every time someone passes around his house on the sidewalk. Light would probably irritate the neighbors, scare passers -by and waste energy. In order to minimize accidental activation, the motion sensor lamp may have a time delay mechanism so that the moment of movement on the edge of the sensor area does not activate light.

Assensor Motion lamp can serve as a highly effective sysThe topic of a thief or intruder, because sudden activation of light reveals the activities of the intruder and suggests intruders that it is monitored. In some cases, the camera will be activated simultaneously with the motion sensor lamp to record the activity of the individual passing areas of the sensor. If the sudden activation of the light does not scare the intruder away, the camera can help the police to find the intruders and verify his identity in court.
