Hi! I have been using NC450 and they work fine, but one issue that has always been there and never has been solved is this: I watch the camera views through Agent DVR (first v. 3.x.x and now the latest) and this has been a problem in every Agent DVR version. PTZ-control works but when zooming in the software the connection somehow get lost. The view is still working, meaning that the video stream is working but I can not control it. So I have to reboot it through TP-link web app, or Android app or by physically power it off/on. Has anyone had the same experience? Solutions? Can I somehow reboot in Agent DVR. This is what the error log says: 20:13:09 PTZContinuousMoveAsync: The underlying connection was closed: The connection was closed unexpectedly. at System.Runtime.AsyncResult.End[TAsyncResult](IAsyncResult result) at System.ServiceModel.Channels.ServiceChannel.SendAsyncResult.End(SendAsyncResult result) at System.ServiceModel.Channels.ServiceChannel.EndCall(String action, Object[] outs, IAsyncResult result) at System.ServiceModel.Channels.ServiceChannelProxy.TaskCreator.<>c__DisplayClass7_0`1.b__0(IAsyncResult asyncResult) at System.Threading.Tasks.TaskFactory`1.FromAsyncCoreLogic(IAsyncResult iar, Func`2 endFunction, Action`1 endAction, Task`1 promise, Boolean requiresSynchronization) --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at CoreLogic.Onvif.ONVIFDevice.d__69.MoveNext() 20:13:09 PTZContinuousMoveAsync: The underlying connection was closed: The connection was closed unexpectedly. at System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult) at System.ServiceModel.Channels.HttpChannelFactory`1.HttpRequestChannel.HttpChannelAsyncRequest.CompleteGetResponse(IAsyncResult result) 20:13:13 PTZStop: There was no endpoint listening at http://192.168.0.119:2020/onvif/service that could accept the message.
