This is a security tool that provides peace of mind for overseas travel or returning to your hometown during the New Year's holiday. Ordinary sensor lights won't startle burglars. Burglars won't enter a house if the TV or stereo is playing. By connecting the sensor outlet to the TV, radio, and lights in the room, the switch will automatically turn on when it gets dark and turn off when it gets bright in the morning. It's new, but the cord is slightly discolored, so please refrain from purchasing if you are concerned. Burglars and thieves won't enter a room where the TV or radio is playing. Even during long business trips or travels, the switch turns on automatically every day, so it won't be noticed that you are away. If possible, it is effective to install them in several places such as the living room and kitchen. It is more effective than external sensor lights even in stores. You can also set the time. It's a bit old, so there is some discoloration on the outlet part, so it's priced lower. Regular price: 6,800 yen. New and unused. We do not offer discounts because we want you to purchase without worrying about price fluctuations due to negotiation.
