It's not worth the money and it doesn't always show or catch people until they have left as playback on the app is Jerky and inaccurate its better to buy a cheap wifi camera off amazon and fit it yourself....replying to response its not notification issue it is general playback which is Jerky and it doesn't see the people who come past it till they have passed, the use of finger controls to move through images captured is not accurate so when going through playback it buffers which isn't helpful
