VENUE PROPERTIES AND RADIATOR POSITION
Different elements present in the room can effect the infrared signal transmission. Most objects reflect
infrared, with the exception of dark and rough surfaces that absorb a large portion of the infrared signal.
Infrared will not pass trough objects that are opaque to visible light, therefore it is important to position your
radiators carefully.
Do not put objects between the radiator and the receivers because this will hinder the infrared
signal. This also applies to people, the radiation will not pass through people. Therefore you should
position enough radiators at the correct locations inside the venue for optimal coverage.
Figure 1-8 Effect of positioning the radiator too low, preventing people sitting in further rows from picking up
the infrared signal
Figure 1-9 Correct position of the radiator, participants on all rows can pick up the infrared signal
If the venue permits it, the receiver can pick up reflected infrared radiation as well as direct radiation. The
radiation can be reflected by the wall, floor or other objects present in the room.
