It seems that you're in Germany. We have a dedicated site for Germany. Familiarization with the infrared world Thermal imaging systems extend human perception beyond the visible spectrum. Since their principle is based on the natural emission of energy by physical bodies, they represent today the subject of a great deal of interest in many fields, whether in the military field or in industry or in research laboratories.

A passive infrared sensor PIR sensor is an electronic sensor that measures infrared IR light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications. PIR sensors detect general movement, but do not give information on who or what moved. For that purpose, an imaging IR sensor is required.

A motion detector is an electrical device that utilizes a sensor to detect nearby motion. Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area. They form a vital component of security, automated lighting control , home control, energy efficiency, and other useful systems. An active electronic motion detector contains an optical, microwave, or acoustic sensor, as well as a transmitter. However, a passive contains only a sensor and only senses a signature from the moving object via emission or reflection.

History of infrared detectors

Камень рвал кожу на запястьях. Шаги быстро приближались. Беккер еще сильнее вцепился во внутреннюю часть проема и оттолкнулся ногами. Тело налилось свинцовой тяжестью, словно кто-то изо всех сил тянул его. Беккер, стараясь преодолеть эту тяжесть, приподнялся на локтях. Теперь он был на виду, его голова торчала из оконного проема как на гильотине.

 Сьюзан, - наконец произнес он еле слышно.  - У меня нет семьи.  - Он посмотрел на.  - Мой брак практически рухнул. Вся моя жизнь - это любовь к моей стране.

Выслушай меня внимательно, - попросил Стратмор. Сьюзан была ошеломлена.

    Basically, these types of wireless communications change their frequencies.
