OMV-VX
OUTDOOR VISUAL VERIFICATION DETECTOR
Sensitivity adjustment
The OMV-VX detector comes with the capability of adjusting the sensitivity level of the PIR. It can improve the
detection or, on the contrary, reduce false alarms. Raising sensitivity will raise detection range, the detection field
will be larger and smaller thermal signatures will be detected. You should only use this feature when the site has
been diagnosed as needing this adjustment. It cannot be used to optimize detection as the adjustment may be too
high and generate either false alarms or missed intrusions.
Examples : Plant growth, pets.
Please note that the detector must be installed to prevent intrusions (aim the detector towards an access point),
sensitivity adjustment will have no effect if the installation doesn’t comply with the installation recommendations
described in this document.

Masking lens
The OMV-VX detector is provided with a masking kit. With this kit you
can inhibit specific zones in the detection field because elements in
those zones can generate false alarms, like a tree or a road.
After disassembling the detector, detach the precut elements from
the kit and place them directly behind the lens at the detection beam
location you wish to mask.
Once it is done, put the OMV-VX elements back together as shown
below.
