I had this same problem and couldn't figure it out. I got this reply from Geovision and it sorted the issue
Thank you for writing to GeoVision.
The only possible for this situaion is that you log in an account with fack mask on.
When face mask function is on, video play back will be limited to 1X or lower.
To Enable the Face Mask for an User Account:
1. On the GV-System, click the Configure button, select System Configure, select Password
Setup, and select Local Account Edit. This dialog box appears.
2. Select a Power User, User or Guest account and click the Viewlog tab at the bottom.
3. Clear the selection for Display detected faces to blur human faces when the user wa
recorded events in ViewLog.
4. Click OK.
I hope that I was able to help you with your issue. However, if you are still having any problems, please don’t hesitate to reply to this email and let me know. I’d be glad to help.
Best regards,
