If you have not done so already i would recommend that you update the GeoVision NVR software as well as the cameras Firmware.
You can download the latest camera firmware here — https://www.geovision.com.tw/english/5_3.asp
Also you can request the latest NVV Software here — https://www.usavisionsys.com/forums/viewtopic.php?f=9&t=26
I hope this helps. Please let me know if this does not fix the issue.
