Troubleshooting
1. The HT-CAM-4K-EPTZ is connected using USB 3.0 cable into a PC but there is no video
from the camera shown on the soft codec application.
a. Confirm the blue LED light on the camera is on.
i. If blue LED is off:
1. Confirm the USB 3.0 cable is securely connected on both the
camera and the PC.
2. Check the quality of the USB 3.0 cable to ensure it has not been
kinked or accidentally cut.
3. Go into the soft codec application and make sure the “HD Camera”
is selected as the preferred camera.
4. Try using a different application, such as the built-in camera
application on the PC, to verify video can be seen there. (NOTE: if
using the built-in camera application and video is shown, the
camera will not be shown in any other application until that
application is closed.)
ii. If blue LED is on:
1. Verify the PC has no updates pending (Windows will often disable
features when new updates have been released and those features
are not enabled until updates are installed.)
2. Restart the PC to verify it is operating correctly.
2. The HT-CAM-4K-EPTZ is connected using USB 3.0 cable into a PC but the far end
