The present invention relates to a CCTV system reduced in problems caused by insects. According to the present invention, the CCTV system includes: a camera device for taking an image of a surveillance area in a daytime mode or a nighttime mode, such that when taking the image in the nighttime mode, yellow light having an insect evasion wavelength band that the insects including midges evade is radiated together with infrared light to prevent the insects from approaching and an image processing device for receiving the image taken by the camera device (100), recording and storing the image by a digital video recorder (DVR), and displaying the taken image through a monitor, wherein the camera device includes a camera module provided in a body of a camera installed to take the image of the surveillance area for taking the image of a day or night in the surveillance area, and an LED module driven when taking the night image by the camera module and including an infrared LED for irradiating with the infrared light for taking the night image and a yellow LED for irradiating with the yellow light having the insect evasion wavelength band, and wherein the camera module includes a lens unit exposed to the camera body for taking the image of the surveillance area, an image sensor for taking the image incident through the lens unit, an image processor for converting an image taking signal outputted from the image sensor into a video signal, and a video image output unit for outputting the video signal converted through the image processor to the image processing device.COPYRIGHT KIPO 2017본 발명은 곤충들로 인한 문제점을 감소시킨 CCTV 시스템에 관한 것으로서, 본 발명에 따른 CCTV 시스템은 주간 모드 또는 야간 모드로 감시 지역의 영상을 촬영하되, 야간 모드로 영상 촬영 시, 곤충들의 접근을 방지하기 위해 깔따구를 포함하는 곤충들이 싫어하는 곤충 기피 파장대의 황색 광원을 적외선 광원과 함께 조사하는 카메라 장치부와, 상기 카메라 장치부(100)에서 촬영되는 영상을 수신하여 DVR(Digital Video Recorder)로 녹화하여 저장하고, 그 촬영된 영상을 모니터를 통해 디스플레이하는 영상처리 장치부를 포함고,상기 카메라 장치부는 감시 지역의 영상 촬영을 위해 설치되는 카메라 몸체에 구비되며, 감시지역의 주간 또는 야간의 영상을 촬영하기 위한 카메라 모듈과, 상기 카메라
