Manufacturer's response to the evaluationLifeSize™ Team 2201. Camera 10x PerformanceThe 10x camera is more sensitive than earlier LifeSize 1080p examples and produces good results at lower lighting levels. The operation of the camera Pan and Zoom controls however does generate a significant level of mechanical noise, the CODECs cooling fan also generates some noise. The auto focus was slow to respond on occasions particularly at wide zoom angles and either locked in or out of focus, a slight adjustment was then required to the pan, tilt or zoom functions to reinitiate auto focus and thus correct the errors.LifeSize: This is a known mechanical issue. LifeSize is working on ways to reduce camera noise and strain on the Tilt motor. Also, other reports on auto-focus and response have led to mechanical reviews on the stop motor.

Improvements have been implemented to date.2. Presentation Frame RateDuring tests between Lifesize Team 220™ systems the second H.239 channel achieved a maximum resolution of 1280 x 720 pixels at around 15 frames per second(the system statistics does not report H.239 frame rate).LifeSize: The presentation channel is restricted to 1280x768 maximum resolution of this current generation of video systems.

To increase the frame rate from 4-5 frames per second when using content that demonstrates motion, the following can be done through the Administrative Preferences:Admin Prefs/Video/Video Quality- Video Bandwidth Balance: Change setting from 90%/10% to 50%/50%- Primary Video Motion: Change setting from 10 to 93. MCU OperationThe MCU operates in continuous presence mode only.LifeSize: Voice Activated Switching is supported.

2.7 meters (9 feet) in front of it; in a multi-user conference room, place a LifeSize MicPod or LifeSize Phone at the center of the participants as their detection patterns are omnidirectional.
