DETECTORS
Detections Systems, Inc. offers a wide range of Sensors. There are three main types:
- Passive Infrared Detectors:
- A Passive Infrared Detector operates by detecting the change in energy that occurs when a body of one temperature passes by a background of another temperature within the detector's field of view. Special signal processing techniques enable the detector to determine whether a signal is caused by a person, or by some other, false alarm source. Interchangeable optics allow the protection area to be customized to meet the needs of the specific application.
- Photoelectric Detectors:
- Photoelectric beam detectors consist basically of a light transmitter and a separate receiver. The transmitter emits an invisible infrared beam to the receiver. If the beam is broken, the receiver signals an alarm.
- TriTechTMPIR/Microwave:
- Detection Systems' TriTech Detectors combine Dual Technology Passive Infrared with Microwave detectors. Microwave detectors generate microwave signals and detect either a reduction or distortion of received energy caused by an intruder.
