I've been using this app for over a year and it is not reliable. The power and/or internet connection goes out on occasions and it is very difficult to reprogram. Also, when the internet provider loose power the camera completely becomes inoperable and it is very difficult to reprogram and reconnect. When reconnecting it gets to the section where you need to enter your last four numbers of the camera serial number, then it freezes up and you can't proceed with the reprogramming/reconnection.
