CENTRALIZED MONITORING SYSTEM FOR CAPTURED IMAGES

PROBLEM TO BE SOLVED: To provide a real-time centralized monitoring system for images. SOLUTION: The system includes a modulator device 16 for establishing a unique carrier frequency and modulating the carrier wave by an imaging signal of a camera 14, an optical multiplexer 20 for supplying an output signal of the modulator 16 to a signal transmission cable 18, a demultiplexer 22 connected to on end of the cable 18 and for separating the output signal of the modulator 16, a demodulator 24 for demodulating the output signal of the modulator 16 that is output from the demultiplexer 22, a monitor 26 for receiving an output signal of the demodulator 24 and reproducing an image photoed by the camera 14, a power supply device 28 for supplying AC current, which is frequency-converted to a frequency higher than the one of a commercial power supply, through the cable 18, and a power supply acquisition device 34 for acquiring power of power supply and driving the camera 14 and the modulator 16.
