The RoboTRAK system is designed for environments without stray IR, but tuning can compensate for a
limited amount of certain types of stray IR.
The IR camera's web interface provides adjustments to compensate for IR interference. These
adjustments may help in cases where the stray IR is significantly less intense than the IR from the lanyard.
They will not help if the room is flooded with IR.
Stray IR Mitigation Cheat Sheet
Problem
Adjustment
Over-adjusting looks
like...
Light fixtures emit
significant IR
Mask top area – increase. (Tracking page, Tracking Limits
tab)
Tracking may become
erratic when the
presenter is far from
the camera.
Reflective tabletops
or other objects near
the bottom of the
frame
Mask bottom area - increase. (Tracking page, Tracking
Limits or Advanced tab)
Tracking stops when
the presenter
approaches the
camera.
Bright area
(IR bloom)
Max bright pixels - decrease. (Tracking page, Advanced
tab)
Tracking may become
erratic.
If the problem is near the edge of the presentation area:
on the appropriate side to
exclude the stray IR. (Tracking page, Tracking Limits tab)
You may also need to reduce the lanyard search pan limit
on the same side. Lanyard search pan limits must always
be inside the area defined by the IR tracking camera pan
limits.
Part of the presenter's
preferred area may be
out of tracking range.
Camera tracks a
reflection of the
lanyard
Brightness threshold - increase. (Tracking page,
Advanced tab)
Tracking may become
erratic.
