User-Friendly Interface | Video Clip Playback | PiP & PTZ Control | Fisheye Dewarp | Mobile Surveillance App iViewer


Dear iViewer users,

We deeply apologize for the authorization issue when using the iViewer App. Users with iOS 10 devices may encounter connection failures or authorization issues when trying to connect VIVOTEK NVRs via iViewer.

The issue has been confirmed to be caused by an iOS authorization mechanism change and has been reported to Apple Inc.

The updated NVR firmware are released now. Please check product page of ND8322P, ND8422P, ND9441, ND9541, and ND8321 to download the latest firmware.

Thanks for your understanding.
