Sorry for this purchase, come on, are many negative points:
1-the video call on the cell phone worked only on the first day
2-the audio in moments is open even closed in the application, where it is possible to listen to the whole conversation
3-The campaign needs to be very close to synchronize the call, 2 MTS or more that this does not work.
4-a week of use and the battery is in 30%, without much use.
Do not recommend, even in Alexa for being Tuya I could not recognize the device, for this and other points I regret the purchase.
