The free version worked fine and so I paid for the pro version. This worked well for a few weeks then stopped working. Nothing I did would get it to work. I deleted the camera and re-added it but nothing. I emailed support but no reply, even after over a month. I gave up as clearly they won't return my money. Other apps work fine. This app then started working and lasted about a week and has now stopped working again. Poor service and poor app.
