About two years ago, the house I am living in was visited by police when they searched for unlawful property. During the search, officers were veiwed entering the house with a large wooden toolbox that required two of them to carry into the house. After two hours of unsuccessful searching, the officers packed up their gear and left us a destroyed house to clean. The first thing I did was to disconnect all of the power consuming items within the house and check the power lines at the fusebox for any signs of resistance. Three rooms showed resistance at the box. Then I checked the phone lines going to the house and found resistance that has capacitive properties to it even though the lines were clearly open at the jack. Additionally, when a simple frequency detector was raised to the round air vent in one of the rooms, it indicated that a signal was present. When I removed the air vent, I was unable to see anything with a mirror as far as 8 feet back, so I put a wireless camera on an r/c vehicle and ran it down the tube. What I found was a 10" brushless windmill that generated power to a lithium-ion battery supply which powered a small transmitter with dual band digital capability. (a cellular phone with a remote interface hooked to it). So while my air conditioning ran during the day, this little gem soaked up all the juice it would need to continue transmitting non stop for an unlimited amount of time. The phone lines that showed resistance were the black and yellow lines that are seldomly used in most residential households. This way the house could be monitored right from the office desk of the agency employing this capability. I still have not located the source of the drain on the power lines going to the three rooms. I've done everything but pull the wires out completely. Does any of this sound familiar, any suggestions ?
