3.
Providing detectors are installed in accor
dance with NetVu Ltd.’s recommended best
practice the upper half of the view will be capable of being more sensitive than the lower
half of the view. This is achieved by using different parameters in the regions located above
the half way mark and those regions located below the half way mark.
Note:
Any area of the detector’s view which does not fall within a region is NOT being monitored
and smoke or flame present in such areas will not be detected until it spreads to areas that are
within the detection zones.
The only rules relating to detection regions are:
●
There must be at least one region
●
They must not overlap
●
They must be of a pixel size that is divisible by 8. If not, the configuration tool will highlight
the region in red in the “region list” so
that attention is drawn to it.

They must be of a pixel size that is divisible by 8. If not, the configuration tool will highlight
the region in red in the “region list” so that attention is drawn to it.
At the top of the regions page is a camera drop-down box, here you select the detector you wish
to configure. On selecting a detector, the image from that channel will appear in the page and be
overlaid with any existing regions. No overlay means no regions are set.
If no regions are present they can be added or created in a number of ways:
1.
A grid or regions of equal size can be created by putting the number of horizontal and
vertical regions required into the “X” and “Y” boxes beside the “Grid” text. (Note: maximum
region count is 16 so the grid numbers must not result in a grid which would exceed 16
regions). The “Default” button will populate a 4 x 4 grid. Once the “X” and “Y” grid
numbers are populated, select the “Go” button to create the grid overlay in the web
-page,
then select “Save” to
save it to the FireVu detector.
2.
Individual regions can be created by selecting the region in the “Regions” drop
-down box
and then selecting “Enable” in the other drop
-down box, the region will then appear in a
default grid position and can be amended from there if required.
3.
Once created regions can be altered manually using the mouse by positioning the cursor
over either the top left or bottom right corner of the region and then clicking the left-hand
mouse button and dragging the cursor in the direction required to alter the region as
wanted.
Note:
If you attempt to set a configuration which would exceed 16 regions then only the first 16
will be created, starting from the top left and working across to the right and then down, if left this
will result in an area starting from the bottom right of the view not being covered.
Once created regions can be moved and re-sized in two ways:
