Abstract: The security detection system includes a detection unit capable of detecting a condition, said unit in communication with a remote central server. Where the detection unit is connected to the server via a dial-up modem, the detection system may be connected to a telephone seizure unit. Upon occurrence and detection of a condition, the detection unit prevents a telephone from communicating with a main telephone line, while still allowing said detection unit to communicate electronic information to the server, even upon lifting of the telephone receiver from the base. Once electronic information is sent to the server, a programmed database of the server may send the information according to a pre-determined designation. The server monitors whether a designated party has responded to the information, and if not, may send the information to a human monitoring station. The designated party may request and receive additional information from the detection unit, via the server.
