Thanks seller.

It works perfectly. The pairing of sensors is very simple, and the quality of both sensors and controllers is well above other alarm systems that I have previously bought and have cr2035 batteries at last! It also works smoothly with a wireless siren purchased here (the blue and white circular) and when it jumps better not be around. Totally recommended.

Delivery to Kharkiv 17 days (by China 4px via Poland, by Ukraine-new mail). The equipment fully corresponds to the declared, there is a Russian language. Camera and alarm work through applications. Until I installed, I will add a review later.

Connected, everything works, language Russian is, SMS come. It is not known for how many batteries for sensors. The motion sensor can be powered by the wire of the microUSB. I haven't tried it yet. The rest are only from batteries.

The alarm is thick, the Russian language is, says the male voice. Manage and configure available. I'm happy with the signal. But Och. Long delivery. She came to Ukraine in 87 days. The seller assures all the fault of the pandemic
