Masking the Motion Detector Window
To prevent movement detection in unwanted areas or to shield off shrubs etc. which
can cause false activation in the wind, the detection area may be reduced by masking
off sections of the lens using either the window mask curtain provided or electrical
insulation tape. To discover how much screening is needed, first obscure the detec-
tor’s lens with insulation tape, progressively covering more of
the lens until the required detection area is achieved. The top
half of the motion detector lens deals with long-range detec-
tion, the bottom half is for short range. Then simply cut a piece
of the plastic window masking curtain to cover the same area
as the tape. Remove the tape from the lens (ensuring that any
adhesive residue is removed) and clip the cut masking curtain
into the window recess.
Alternatively, the motion detector can be re-positioned in a
more suitable location.
