Abstract
본 발명은 도어비젼(DOOR VISION)에 관한 것으로, 특히 2선식 도어비전에서 음성 통화시 증폭이에서 전류를 과소비하여 부하가 변동하는 관계로 발생되는 모니터회로로 제공되는 전원의 변동을 방지하도록하는 2선식 도어비전의 화면간섭 방지회로에 관한 것이다.The present invention relates to a door vision (DOOR VISION), in particular, in a two-wire door vision to prevent the fluctuation of power provided to the monitor circuit generated due to the load fluctuations due to excessive consumption of current in the amplification during voice call 2 It relates to a screen interference prevention circuit of a wire door vision.
본 발명은 전원과 영상 및 음성을 통합하여 전송 및 공급하는 2선식 도어비젼에서, 음성통화가 이루어지는 순간에 음성증폭을 위한 증폭기에서 전류를 과소비하여 부하가 변동하는 관계로 발생되는 모니터회로로 제공되는 전원의 변동을 효과적으로 방지하도록 하는 발명이다.The present invention provides a two-wire door vision that integrates and transmits and supplies power and video and audio, and is provided as a monitor circuit generated by a load fluctuation due to excessive consumption of current in an amplifier for amplifying voice at the moment of a voice call. The present invention effectively prevents fluctuations in power supply.
