Residential Tuya Smart Gsm Wifi Alarm System for Home Wireless Security Alarm House Smart Life App Control Work with Alexa

It took a bit to get it working but fine. To lock the keyboard, you can set a code in the settings menu. And for the SIM card to work for me, the PIN code must be canceled.

Everything arrived well and everything works perfectly.

Quite good, actually I don't have them in my hand yet because I sent them somewhere else and they send them to me from there, but I have had other models from the same brand and they work perfectly, in fact I have them installed at home and they have prevented me from being robbed on several occasions since where I live there are plenty of thieves daily. I hope these work the same and everything is fine as soon as I have them. Greetings to everyone here, as soon as I have them I will upload photos of the other one, but let yourselves be guided by this one.

Perfect

For now, everything arrived well, after trying it I extended my review. I want to clarify that the product arrived well protected.
