4. After 30 seconds, power on the NAT device.

wired and wireless network connections.

ViaVideo and ViaVideo II Hardware Issues
The Polycom PVX software may intermittently fail to recognize the ViaVideo cameras.
If this happens, close the camera’s shutter and open it again. You may need to restart the
Polycom PVX application if the camera preference is set to “Use ViaVideo hardware if
present”.
If you do not plan to switch between using a ViaVideo camera and a web cam, you
should configure the system to always use ViaVideo hardware. This prevents Polycom
PVX from switching to web cam mode if a ViaVideo camera is not detected on startup.
To do this, click Setup > General.
If you use a laptop docking station, you may encounter difficulty while loading the
ViaVideo camera’s firmware. If this happens, connect the ViaVideo unit directly to
computer’s USB port.
If you experience problems loading ViaVideo firmware through a USB hub, connect the
ViaVideo unit directly to computer’s USB port instead.
Video Issues
H.264 video is only available when you are using a web cam on a PC running with a 1.5
GHz Pentium 4 processor or greater. At high call speeds, the software will switch to
H.263. In some cases connecting at a lower speed with H.264 will produce better results.
With some web cam drivers, the camera appears to be connected when it is not actually
connected. The system does not display an alert and no video is displayed locally or
during a call.
Users may experience no video from the Polycom PVX application after a computer
reboot or upon leaving hibernation or standby mode. To correct: Cycle the power switch
to refresh the ViaVideo camera’s firmware.
Users may experience no video from the Polycom PVX application after a computer
reboot if Auto-start Application in Background under the General tab is checked. To
correct: Open the system’s Windows Task Manager, click on vvsys.exe and click End
Task. Exit the Windows Task Manager and restart the Polycom PVX application.
For optimal low light calibration with the ViaVideo camera, the camera lens must be
completely covered. To cover the lens, move the slider on the front of the camera to the
middle position. With the slider in the middle position, the camera is still running but the
lens is covered.
If the lens cover is not completely closed during calibration, you may need to repeat the
calibration process. To repeat the camera calibration:
1. Power off the ViaVideo camera.
2. In the Polycom PVX application, go to Setup.
3. Click Reset to restore default factory settings.
