The "Witness"
uses "Surround Vision" technology to monitor multiple
detection zones simultaneously. A total of eight individual detection
zones, positioned every 45° are electronically scanned once every 30
milliseconds for motion detection activity.
One of our unique detection zone features is known as
"Animal alley". This allows consumers a customizable installation
method to fit their application requirements. Simply lowering or
raising the "Witness" height during installation can adjust the
vertical distance of the "Animal alley". Below are two detailed views of any
one individual detection zone.
