an outdoor camera

Abstract

The invention discloses an outdoor camera, which belongs to the technical field of cameras. The key points of the technical solution include a casing, a protective cover is arranged on the surface of the casing, a camera assembly is arranged inside the casing, and a part of the casing is The inner wall of the side is provided with a protective lens, the other side of the inner wall of the housing is provided with a cooling fan, the other side of the housing is threadedly connected with a ventilation net cover, and the inner wall of the housing is provided on one side close to the ventilation net cover There is a windshield, the windshield is funnel-shaped as a whole, and the opening on the side of the windshield close to the cooling fan is smaller than the opening on the other side, and the edge of the windshield is in contact with the inner wall of the housing. The top of the housing communicates with an air guide pipe located between the cooling fan and the windshield. The present invention can effectively reduce the possibility of dust accumulation on the mirror surface while maintaining the original volume of the camera and based on the heat dissipation of the camera. Its mirror cleanliness.

Description

technical field [0001] The present invention relates to the field of camera technology, more specifically, to an outdoor camera. Background technique [0002] The camera is a device that uses lenses to project the optical image signal of the observed object onto the photosensitive component, and processes it into a digital signal recognized by a computer through components. As a key component of the camera, the lens directly affects the quality of the image. The cameras in the surveillance field are generally installed at high points indoors and outdoors. Dust will adhere to the lens of the lens if it is left for a long time. [0003] At present, it is common to install a wiper to clean the lens of the camera. A sensor is installed on the camera, and the wiper is installed at the front of the lens. When certain water droplets are attached to the lens, the sensor will trigger the wiper to clean the lens after detection. To prevent scratching the lens, the wiper is made of r...

Problems solved by technology

The cameras in the monitoring field are generally installed at high points indoors and outdoors. Dust will adhere to the lens of the lens if it is left for a long time.

[0003] At present, it is common to install a wiper to clean the lens of the camera. A sensor is installed on the camera, and the wiper is installed at the front of the lens. When certain water droplets are attached to the lens, the sensor will trigger the wiper to clean the lens after detection. To prevent scratching the lens, the wiper is made of rubber, and the wiper is exposed to the environment, and it will also stick to dust and fine particles. If you wipe it with it, there will be a risk of staining and scratching the lens. In addition, use a wiper to clean it The lens needs to add more mechanical parts to the camera, which not only increases the size of the camera, but also more mechanical parts are prone to defects, resulting in abnormalities in the wiper cleaning process
