Very happy with this product. Mobile alerts, remote control, excellent night vision 'Meets my needs perfectly. Good image and fluid video. Pleasantly surprised by the room monitor quality too, the sound is very good. The remote control works well even in 3G. Personally, I also use it to keep an eye time to time on my animal, and especially back to see my kids from school. Quibbles: I do not see the difference in picture quality between HD and SD on my mobile screen 'Fluidity video depends on your Wifi, attention to the distance. My home is approx. 4m / 5m and it fonctione well beyond perhaps problematic.
