Anybody thinking about getting xiaomi cctv, forget it, buy some other brand. I have 2 xiaofang cameras, very buggy, off by itself, connection stopped at 91%. I replaced the sd cards to expensive endurance type, no use. It wasnt the internet connection, I have replaced the modem, it wasnt the power source, have tried different chargers. I believe the China xiaomi server traffic is already overloaded. Keep it simple, make one app for cctv, one app for home appliance, one for lighting, dumbazz..
