Problems solved by technology

In the daytime, due to infrared and other stray light entering the CCD, it will interfere with color reproduction, such as green plants becoming grayish white, red clothes becoming pale, etc. (especially in sunny outdoor environments); at night, due to the filtering effect of the bimodal filter, the CCD doesn't make good use of all the light, noise and its low-light performance are unsatisfactory

Abstract

The invention relates to a lens module for surveillance camera shooting. The lens module comprises a connector as well as a camera shooting module PCB (Printed circuit board), an image sensor, a lens bracket and a lens which are connected in sequence in the connector from bottom to top, wherein a dual-filter switcher is arranged between the lens and the lens bracket, and the positive and negative electrodes of the dual-filter switcher are connected with a PAD on the camera shooting module PCB so as to provide a power supply and switch instructions. The lens module has the beneficial effects that the lens module can be used day and night, and the image is not distorted; infrared light can be filtered to ensure the color of images is softer and is consistent with vision colors of human eyes; and simplicity and convenience in assembly are achieved and the space is saved.
