Gun type camera

Abstract

The embodiment of the invention provides a gun type camera. The gun type camera comprises a camera body; a partition piece is arranged in the camera body, the partition piece divides the inner space of the camera body into a first cabin and a second cabin located behind the first cabin, the first cabin is a closed cabin, and a wire penetrating opening used for allowing an external cable to penetrate is formed in the side wall of the second cabin; an optical device group is arranged in the first cabin. According to the gun type camera provided by the embodiment of the invention, the internal space of the camera body is divided into the first cabin and the second cabin by the separation piece, the first cabin is a sealed cabin adopting a sealed design, and the optical device group is arranged in the first cabin, so that the optical device group can be well isolated from external air. A threading opening of a camera tail wire is formed in the side wall of the second cabin, and in the field installation process of the gun type camera, in order to conveniently penetrate an external cable, the second cabin can be opened for threading operation.

Description

technical field [0001] The present application relates to the technical field of surveillance, in particular to a bullet camera. Background technique [0002] In the related art, in order to avoid the impact of the humid environment on the optical device, the body of the bullet camera is usually designed with a seal. However, in the process of on-site installation of the bullet camera, sometimes the body needs to be opened in order to pass external cables into the body to facilitate wiring operations. This can result in the entry of moist air from the outside into the interior of the fuselage, which may adversely affect the optics inside the fuselage. Especially when it is installed on-site in a humid and salt spray environment, the impact on the optics of the bullet camera is extremely serious. For example, moisture itself will affect the imaging effect of the camera module, and will also corrode the optical devices; while the salt or acidic substances in the salt spray e...

Problems solved by technology

This allows moist air from the outside to enter the fuselage, which may adversely affect the optics inside the fuselage

Especially when installing on-site in humid, salt spray environment, the impact on the optics of the bullet camera is extremely serious

For example, moisture itself will affect the imaging effect of the camera module, and will also cause corrosion to the optical device; while the salt or acidic substances in the salt spray environment will precipitate on the surface of the optical device, causing erosion or even damage to the optical device

[0003] Therefore, there is an urgent need for a bullet camera with better moisture-proof effect, so as to avoid the problem that the optical device is in contact with the humid air during the field installation process
