PURPOSE: A communication control method of a monitoring camera and a monitoring camera adopting the same are provided to use the non-periodic characteristics of a received noise to judge whether or not a noise exists depending on a reception time. CONSTITUTION: If the input time of a received signal of a communication target object is not shorter than a certain time, a communication interface(109) judges the received signal as a noise. A video signal generator(108) converts the digital video data of a main control unit(107) into an analog video signal to input the converted analog signal to the communication interface. The main controller transmits the video signal of the video signal generating unit to a communication target while passing through the communication target object at a VBI(Vertical Blank Interval) transmitted to the communication target. |
