Basic Parameters
Blackboard Zone: define the effective zone
of BLS trigger, displayed as a blue rectangle.
Generally it covers just the whole blackboard.
Bottom as per that of blackboard. To avoid
faulty detection, do not cover floor beneath the
blackboard or the area that may be touched
by the lecturer when he is not writing on
blackboard.
Blocking zones: There are 8 blocking zones
shown in red rectangle to avoid interference in
BLS and podium areas, they can be
configured independently. The moving
objects inside the blocking zones of the
full-view camera will not be detected and
tracked while the tracking camera still tracks
the lecturer head.
Interval Before Action: Used to avoid
frequent switch of BLS in short period. It’s the
duration of time in seconds when BLS detects
the blackwriting ends. For example, if there is
3 seconds of non-blackwriting, the
blackwriting end then is confirmed.
Detecting Sensitivity: 0~6 levels. Higher
level may cause higher faulty detection rate.
When it’s 6, any object in the BLS area (for
example, shadow) may be detected as a
blackwriting. So 0~5 is suggested. Low level
is suggested when blackboard is short.
Lecturer Tracking Camera IP Address:
Setting of LTC IP is necessary. When BLS
detects blackwriting, the camera of the IP
address will be notified to perform a shot of
blackwriting.
NetworkTest: to test if BLS and LTC is
connected in the network.
