The VXS-AM by Optex is part of the VX Shield series range of outdoor PIR sensors. It provides 40' by 90° passive infrared coverage, ideal for residential and small commercial sites. Featuring customizable design and high accuracy against false alarms, its equipped with digitally-enhanced signal recognition logic as well as super multidimensional analysis (SMDA). Analyzing detection patterns and environmental information, SMDA improves immunity against temperature changes or moving trees and vegetation, reducing the risk of false alarms.

The VX Shield series has been designed to make the installation phase as easy as possible, with the inclusion of a rotation lock to simplify opening and closing of the detector's cover. Sensor adjustment components have also been colored blue to make it obvious which parts are used to manipulate the sensor detection area. A spirit level has been incorporated as well, along with an automatic walk test mode which starts automatically when the cover is closed.
