Plan Your Sensor Installation (cont.)
Interference and IR Coverage
The FrontRow Symbio system uses infrared light to transmit the voice signal from the microphone
to the sensor in the ceiling/wall sensors. Proper placement of the sensors is critical for optimal
system performance.
a. Adjacent classrooms that use FrontRow infrared systems can interfere with each other if the
rooms are separated by windows. The windows allow the infrared light to “escape” from the
classroom only to be picked up by the sensors in the adjacent classroom, causing interference
and “cross talk”. Be sure to recommend window coverings to the greatest extent practical
when using the system.
b. Direct sunlight can reduce system performance. Be sure to recommend window coverings to
the greatest extent practical when using the system.
c. Infrared light has better reflection off of white and glossy surfaces. The ceiling sensor can be
placed to help provide coverage in areas where the signal may be weak due to insufficient
infrared reflection.
