TO CAMERA
•
Place the light meter perpendicular to the light sensor (since this is what the camera sees).
•
Check that the light meter dome is fully retracted.
•
Use a tripod to maintain height consistency.
The lighting should meet the following requirements:
•
The light levels for the participants seated at seats 1 through 6 should be between 30 and
70 foot candles, with an ideal measurement of 45 foot candles. The difference in light levels
between any two participants must be less than 10 foot candles.
•
The lighting temperature should be between 3200K and 4500K, with an ideal measurement
of 4100K.
The OTX Complete Experience Kit lighting plan is shown on page 28. You may want to refer to this
plan as a reference when choosing and installing your own lighting. For additional information to help
you choose lighting that is comparable to the OTX Complete Experience Kit lighting, see the
specification sheet for the lights:

If your room is larger than the recommended room size:
If your room is larger than 22 ft 4½ in (6.82 m) wide x 15 ft 6 in (4.72 m) deep x 8 ft 8 in (2.64 m)
high, any lighting in the room that is outside of the OTX footprint could cause interference with the
OTX lighting. (Note that this pertains to rooms with and without the OTX Complete Experience Kit,
although Polycom does recommend that all rooms that are deeper than 15 ft 6 in (4.72 m) front-to-
back should include a Complete Experience Kit.)
To reduce the probability of interference from other lights in the room:
•
Remove any lights within 4 ft (1.21 m) of the sides or back of the OTX footprint. This “keep-
out” area is shown in blue in the following illustration.
•
Check that there are no lights within the 70° field of view of the cameras. This area is also
shown in the following illustration.
