New Hik-Connect App
Hikvision are now starting to phase out their iVMS-4500 app and customers are starting to have problems with Live View and Remote Playback.
If you find yourself in this situation just download and install the new Hik-Connect app and login with your existing information.
For iPhone the app can be found in the AppStore - just download and install it.
For Android the app has to be downloaded from Hikvision's website at appstore.hikvision.com where you can find the .APK file. To install it you need to enable "Allow installation of apps from unknown sources", under your Security settings. This is a security measure so things cannot install behind the scenes without your knowledge.
Once the app is installed you can check everything works correctly before removing the old iVMS-4500 app.
When new updates are available you will be prompted by the app if you'd like to download them!
