Came with an abnormal rear camera, the rest works fine.
In contacting the seller there is no possibility to get partial credit or alternative camera but only replace everything ….

The key arrived in 2 weeks. As I set to complete the review. I want to know how to use it paired with emergency bulbs, probably in no way.

2 weeks after purchase, the sensors PM2.5 and PM10 stopped doing. Stopped running these sensors when no one was at home. The Air Analyzer does not work with Mi Home, at least in Russia it is. Nowhere is it written about, and the seller could not help. In the Mi Home list there is simply no this gadget. Tried through an Android and through an iPhone, there is no one connection. Built-in cooler whistling, sound type ultrasonic. It turns out that I bought a device, and I cannot use it fully due to inoperative sensors and I cannot link other devices to it through Mi Home

Camera works perfect, also connecting with the app is very easy. Only the box came really damaged and this was a present so I did not like that. But overal the camera works as it should and got shipped fairly fast.

Cool stuff. Works instantly. For the passageways will not be suitable.
