Passive infrared

Type of Interior Sensor Passive infrared (PIR) Presently the most popular and cost-effective interior sensors. PIR detectors monitor infrared radiation (energy in the form of heat) and detect rapid changes in temperature within a protected area. Because infrared radiation is emitted by all living things, these types of sensors can be very effective. [Pg.170]

Free-standing sensors—These sensors, which include active infrared, passive infrared, bistatic microwave, monostatic microwave, dual-technology, and video motion detection (VMD) sensors, consist of individual sensor units or components that can be set up in a variety of configurations to meet a user s needs. They are installed aboveground, and depending on how they are oriented relative to each other, they can be used to establish a protected perimeter or a protected space. More details on each of these sensor types are provided below. [Pg.181]

Dual-technology sensors consist of two different sensor technologies incorporated together into one sensor unit. For example, a dual technology sensor could consist of a passive infrared detector and a monostatic microwave sensor integrated into the same sensor unit. [Pg.182]

The JSLSCAD is a passive, infrared detection unit employing Fourier Transform Infrared Spectrometry. The device is designed to detect nerve and blister vapor clouds at a distance of up to 5 km. [Pg.250]

Preliminary studies for airborne systems were reported by Meeks et al. (87), who studied microwave radiometric detection of oil slicks. A couple of years later, Fantasia and Ingrao (88) and Ingrao et al. (89) described the development of an experimental airborne remote sensing system for oil spills, based on laser-stimulated oil fluorescence. At the Tenth International Symposium on Remote Sensing, in 1975, several techniques were reported, including a passive infrared (90), radar observation of spills (91), passive luminescence with a Fraunhofer line discriminator (FLD) (92), and active luminescence (93) and fluorescence (94).

Given the above statistics security lighting is undoubtedly a cost-effective way of reducing the incidence of arson attacks. In many premises such lights may be operated by passive infrared (PIR) detectors and not only provide illumination but also produce an element of surprise. PIR is also seen as being more acceptable in built-up areas due to the nuisance caused by permanent Illumination. [Pg.144]
