To change the properties of the fixture before inserting, such as the lens size, right-click on the6.
fixture name, and then click Properties.
Result: A dialog box opens with a shaded view of the BTSensor on the left and an image of
its symbol on the right. Use the Appearance tab to change the lens settings for the BTSensor.
Options are 5.5 mm, 8.0 mm, 3.5 mm for Slim 13E. For s250e BTSensor options are 5.5 mm,
8.0 mm.
To place the BTSensor, move the mouse over a hang structure, and then click. Continue placing7.
this type of fixture by clicking on the other hang structures as desired.
Note: BTSensors can be hung in Space without a hang structure.
Right-click and select Finish placing fixtures from the menu to finish placing the fixture.8.
Result: BTSensors will be hung in virtual space. BTSensors will emit a red beam to represent
their field of vision.

Example of BTSensor Placement
In CAD mode, BTSensors can be hung in the venue exactly the same as fixtures, from any pipe or truss.
In this example BTSensors are hung around the perimeter on pipes represented in yellow, a mannequin
in orange is at the origin of the room.
When BTSensors are hung, the BTSensor’s field of view will correctly project in the visualization. A
BTSensor field of view of in BTWYSIWYG is depicted as a red beam Everything in the red beam is what
the BTSensor can see.
Tracking can only occur when two or more BTSensors see the same area at the same time. By selecting
multiple BTSensors, we can see their field of view and where their vision overlaps. Overlapping views are
depicted in BTWYSIWYG as a deeper red then an individual view.
Two BTSensors whose field of view are overlapping. The deeper red in the center is the overlapping area
where tracking can occur.
