I have Hikvision DS-2CD2032F-I. Using iOS mobile viewers IVMS or EZVIZ, when viewing live, the view freezes after about a minute or two and I have to close the app and re open it. My reason for buying this camera is for watching for my special needs son's bus to arrive in front of my house every morning, so this freezing is a major issue. I haven't had this problem with my other indoor cameras that I can view via Safari on my iPad and iPhone. I was hoping that this camera could be viewed on a mobile browser. Any help would be appreciated.
