Info - Update: There is no App support - App has failed.
I have had mine now for nearly 2 years and have it installed on 3 iPhones. In the main it works fine. A bit heavy on battery use. Only problem that I have is in regard to the SD Card. It could be my fault and that I have installed a fake 32Gb card but when the recordings reach about 16Gb of storage the device reports that it is offline and tries to reconnect without success. The push notices work and live viewing still works, but no new recordings take place. Formatting the SD Card restores normal service.
