Precision adjustment using shrouds
Examples
Shrouds may be used to
define the detection zone
exactly as you require in
order, for example, to blank
out or specifically target
paths or neighbouring
premises.
The shrouds can be divided
or cut with a pair of scissors
along the vertical and hori-
zontal grooves. They can be
clipped into the top channel
around the centre of the
lens. They are fixed in place
by fitting the front
cover.
(See below: Examples
showing how to reduce
the angle of detection and
shorten the reach).
