The Passive Infra-Red transducers are based upon a highly reliable Lithium tantalate pyroelectric detector, which combines very low noies with a high signal to noise ratio. The transducers employ very robust construction techniques and can therefore be confidently deployed in the most adverse environments. Both single and dual element variants are available, the latter possesses the ability to indicate direction of intrusion.
