Similar to the LG Hom Bot, Samsung launched tango view where a vacuum acts like a surveillance camera but doesn’t sweep the floor. Operated at 48dB, Wi-Fi is used to connect to the vacuum. It isn’t a problem is it is night that you are trying to surveillance, the microphone and external lighting help alot!
An app has to be downloaded and once everything is set up, the user controls the camera, pretty neat if you ask me. It helps if the crime rate is high and you want to easily keep a watch without leaving your bed at night. This Korean invention should help everyone!
