"Displaying the camera cannot be performed at this time"

[Aubrey White]

We have a receiption desk that uses the ViconNet 4.0 Viewer to see live video from a door in the back of the facility.  I swapped the computer out today, and reinstalled the 4.0 software.  I have it communicating with the nucleus, and the site map etc. all appear as they should.  However, whenever I click on one of the cameras that this station is authorized to view, I receive the error "Displaying the camera cannot be performed at this time".  What are the causes of this error?

 

Thanks.

Most likely the system doesn't have the necessary video card features.

 

Here is a KB on the topic:

 

Please review this information. Any one or combination of these issues can cause this symptom:  ViconNet - message - "displaying the camera cannot be performed at this time"

QUESTION:
When trying to see cameras on my workstation with ViconNet I get a message
" displaying the camera cannot be performed at this time ".

NOTE: Also under powered video card display issues may be seen as system slow down slow video performance; Or displaying multiple cameras or higher quality the system slows down or ViconNet locks up.

ANSWER:
Video driver and video card is the main issue on display problems.  The message is common to issues with video.
Some things to investigate, check and correct.

>The user must be logged into Windows as a full administrator.

>Always use the latest video drivers from the video card manufacturer. Drivers from Windows will not provide the full video card functions to display.

>Check "Hardware Acceleration".
To get there bring up Display Properties (Control Panel or right click the desktop then properties) >Settings>Advanced>Troubleshooting tab>Hardware acceleration should be set to full.

>Some other problems that can contribute to video issues:
  System RAM is used in a Shared memory with on-board video creating a Low memory condition for the video.
Typical memory configurations on machines are 256mb, 512mb, 1gb, etc...
In one scenario, System properties reported 504mb. This is not "rounded binary". It can be assumed the machine has 512mb and 8mb was being reserved for video memory. 504 + 8 = 512. When we disabled all the junk in Device manager (there were extra "devices" installed in "Display adapters") we got back the memory we needed.

>Disable and shut down Net Meeting or any other remote desktop sharing program or other remote access programs.
  Avoid any custom video / multiple desktops / 2nd monitor setup on the video. These all steal ram for video processing.

Also make sure direct X 8.0 or higher is in the system.
The latest version is 9.0c.
Run DXDiag from Run. Click on "Display" tab,
Make sure under..
