When multi-camera viewing fails
The LTS FAQ suggests checking automatic stream switching under System Configuration → Image for error 91, then choosing a stream the device supports.
For choppy or blurred viewing, check the graphics driver through the computer manufacturer’s supported update process. Reduce simultaneous cameras while troubleshooting.
Ask CJSC before changing streaming-server ports or internal configuration files. Those are installation-specific fixes.
