Camera with anti-interference function for public security system

Abstract

The invention discloses a camera with an anti-interference function for a public security system, and belongs to the field of cameras. The camera with an anti-interference function for a public security system comprises a camera body. The camera body comprises a protective shell, a lens group and a cooling fan installed at the bottom of the protective shell. An airflow notch corresponding to the cooling fan is formed in the bottom of the protective shell. The lens group is arranged in the protective shell, the lens group comprises a main board installed at one end of the protective shell and a lens body arranged in the protective shell, and the end, located on the protective shell, of the main board is arranged close to the cooling fan. Water vapor is prevented from intruding into the camera to erode internal precise elements, internal water vapor is prevented from getting damp, and the influence on the camera shooting effect is effectively reduced. Meanwhile, a valve diaphragm opened and closed through air pressure is arranged, automatic closing is achieved, external airflow is effectively prevented from entering reversely, and water vapor is prevented from influencing the quality of shot images.

Description

technical field [0001] The invention relates to the field of cameras, more specifically, to a camera with anti-interference function for public security systems. Background technique [0002] Camera, also known as computer camera, computer eye, electronic eye, etc., is a video input device, which is widely used in video conferencing, telemedicine and real-time monitoring. Talk and communicate with voice. In addition, people can also use it for various popular digital images and audio-visual processing. [0003] The camera generally has basic functions such as video recording, transmission and static image capture. After collecting images through the lens, the photosensitive component circuit and control components in the camera process the image and convert it into a digital signal that can be recognized by the computer. After inputting to the computer through the parallel port or USB connection, the software will restore the image. However, in the actual application of th...

[0003] The camera generally has basic functions such as video recording, transmission and static image capture. After collecting images through the lens, the photosensitive component circuit and control components in the camera process the image and convert it into a digital signal that can be recognized by the computer. After inputting to the computer through the parallel port or USB connection, the software will restore the image. However, in the actual application of the camera, most of the cameras are in the long-term external state, which is inevitably affected by the environment;

[0004] In particular, the cameras used in the public security system need to provide clear images as evidence when monitoring is required. However, when the environment is relatively hot and humid, the water vapor content in the air increases. Environmental influences can easily lead to internal dampness, and the interference of water vapor will affect the camera effect. At the same time, water vapor erosion will reduce the service life in the long run, and also affect the quality of the shooting picture
