When my friend built his house in a remote place, he had to face the threat of burglary, especially when he was absent from his house. In that area there were only few houses and that too are not close to one another. When one of the houses was looted, all the house owners arranged for a meeting and discussed what to do next. The burglary was done so perfectly in a planned manner. So they all planned and installed CCTV systems in all the houses and linked them to the monitors of their neighbors. The inhabitants may switch it on, when they go out of their house and the neighbor could see what was happening in that house. It beeps an alarm when it senses any movement. Using this centralized system, one day they could spot a thief and informed the police and he was arrested. They are now living fearlessly and with peace of mind.
