Hi - I have 4 IP cams w/ a NVR. They were currently setup to be viewed on my phone through Superlive Plus. The app is horrible, and now constantly freezes, and locks up my phone. Can anyone else recommend an Iphone app that works? I don't know too much about the setup, but will try my best to answer any questions. Also, the installer of the system is not reachable, so he can no longer assist....
