8.2. Detection Area
The VX-Infinity series has a detection range of up to 12 metres at a 90° angle. The
detection area is customisable to suit most situations. There are 3 ways in which you
can customise the detection area; detection length, area angle, and area masking
(seen in the next section).
The detection length can be adjusted by moving the Detection
Length Adjustment up or down. The detector needs both PIR lenses
to trigger to generate an alarm; the VX-RDAM requires the microwave
sensor to also trigger. This allows for the detection length to be
adjusted by only changing the angle of the lower PIR, and microwave
sensitivity for the VX-RDAM.
The red beams represent the top and bottom PIR detection zones; the
blue line represents the microwave detection zone. The microwave
sensitivity adjustment must be adjusted in accordance with the detection
length position. The microwave sensitivity adjustment position can be
seen to the right of each image.
