A security sensor system is provided to install a repeating board at a place for security search to connect at least one sensor to the repeating board, and to connect the repeating board to a controller. A security sensor system includes a plurality of repeating boards(120) installed at a plurality of actual spots. At least one sensor(110) is connected to the repeating board to apply an electric signal corresponding to results detected in the actual spot to the repeating board. A controller(200) collects electric signal data outputted from each repeating board, and generates an alarm signal corresponding to results detected in the actual spot. Each repeating board transmits electric signal data to the controller through a serial communication line(210). The controller comprises a converting unit(220) and a controlling unit(230) generating the alarm signal. |
