Johnice has an old house in a small Italian village that has not been inhabited for a long time. Although she has now settled in Milan, this house carries too many memories for her. When she is free, she will bring her family back to the old house. Living in it for a period of time, in order to prevent others from destroying the house, Johnice wanted a clear camera that could see each picture clearly, and had two-way intercom. If bad guys appeared, he could remotely scare them away. So she chose LS-4GS12.
