Hi!
I have experienced that it's better to do all the camera related settings on the camera itself- instead of the NVR. For best result you should use Internet Explorer.
Log in to the camera and share a screenshot of your tripwire settings. I'm pretty the solution is there (I hope!).
I noted another similar thread now that I scrolled through the new posts in the morning. Check this out, it is DMSS/IOS related but it may help you.
I have an ipad and iphone. Both on same IOS version....both on my home network. Both have my NVR on it and can view live footage. Trying to add push notifications. Both have the Apple notification settings allowing notifications and I've got through and set the same notifications for...

Another way to test is to add the camera directly to the app and skip the NVR. This is possible if you run the camera on the same network as the NVR.
Long story short, do you use a NVR with POE? Do the cameras connect directly to the NVR or so they connect to a separate switch?
This procedure is not preferable as it may complicate things, depending on your network experience/skills.
