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.

iViewer is developed to allow users to monitor locations remotely by providing access to surveillance camera video directly from iOS handheld device.

The re-designed and easy-to-use interface allows users to monitor live video from hundreds of cameras within their fingers. The user may access cameras managed by VAST (central & video management software), VIVOTEK NVR, or make direct connections to individual cameras via IP address or LAN search. The iViewer also allows access to two way audio for camera, PTZ and PiP screen control, fisheye dewarp, snapshot and the capability to playback recorded video from VIVOTEK VAST, NVR, even from Camera SD card.
