I've come full circle with Amcrest. I work in video surveillance, and over time Amcrest just continue to work. I think of them like the consumer priced Axis. As far as their app, ditch it - they are ONVIF compatible. I'm currently using mine with both a rebranded hikvision NVR and a home brewed NVR I'm coding myself, plus a few RaspberryPIs running VLC in different rooms.
