In the "Evergrande City" bought by the family house, the property owner and the developer said that the family would install a probe in the living room to monitor whether the family was stolen. Privacy aside. This is not a camera probe, not a monitor, just an alarm. That is to say, after setting, if someone comes in when you are not at home, it will call the police and make a sound, some directly connected to the property management office, and some directly called. It's okay. I have it at home, too, but I've never set it and it hasn't rung.
