PURPOSE: An antitheft network camera is provided to provide a real-time monitoring about the theft and malfunction of a corresponding network camera by measuring the operating voltage or operating current of the network camera. CONSTITUTION: A sensor unit(270) measures at least one value among the operating voltage and operating current of a network camera(200). A control unit(250) determines the normality of the network camera by the comparison of the measured value and the previously set threshold value. Based on a determined result, the control unit generates a signal. A data transceiving unit(240) provides the signal received from the control unit to a terminal.
