SmartCam Notification Lag

I have a Samsung Smartcam HD Pro. The live view works great. My problem is the Remote Detection notifications. When a motion is detected, I do not get a notification for anywhere from 15 seconds to 15 minutes. This makes the camera sort of useless if I am using it for monitoring.

I have a very good wifi connection, so that does not seem to be the issue. Does anyone else have this issue. if so, were you able to correct it?
