Outdoor camera

Abstract

The invention discloses an outdoor camera, which belongs to the technical field of cameras. The main points of the technical solution are that the outdoor camera comprises a shell, a protective coveris arranged on the surface of the shell, a camera assembly is arranged in the shell, a protective lens is arranged on the inner wall of one side of the shell, a cooling fan is arranged on the other side of the inner wall of the shell, the other side of the shell is in threaded connection with a ventilation mesh enclosure, a wind shield is arranged on the side, close to the ventilation mesh enclosure, of the inner wall of the shell, the whole wind shield is in a funnel shape, an opening in the side, close to the cooling fan, of the wind shield is smaller than an opening in the other side, the edge of the wind shield makes contact with the inner wall of the shell, and the top of the shell is communicated with an air guide pipe between the cooling fan and the wind shield. Under the conditionthat the original size of the camera is kept, based on heat dissipation of the camera, the possibility that dust is accumulated on the mirror surface of the camera can be effectively reduced, and thecleanliness of the mirror surface of the camera is guaranteed.

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
