Problems solved by technology

[0002] The ambient temperature for normal use of existing cameras is mostly -30°C to 60°C, mainly because in a limited space, the waterproof structure of the camera is guaranteed by glue sealing, so the nominal use temperature of the glue determines the use environment of the camera , and then limit the camera can only meet the daily use conditions, but can not meet the use of complex and harsh environments

Abstract

The invention discloses a front cylinder assembly, a camera with the front cylinder assembly and a monitoring system with the camera. The front cylinder assembly comprises a front cylinder, a double-color transparent cover pressing plate, and a double-color transparent cover, wherein the front cylinder is provided with a mounting surface, and the mounting surface is provided with a first window through hole and a first light supplementing through hole; the double-color transparent cover pressing plate is provided with a second window through hole and a second light supplementing through hole; the double-color transparent cover is mounted in the front cylinder through a third sealing ring and is axially pressed by the double-color transparent cover pressing plate to be arranged at the upstream of the mounting surface; the second window through hole is aligned with the first window through hole, and the second window through hole and the double-color transparent cover form a light incident channel for allowing light reflected by an object to be shot to enter the first window through hole; and the second light supplementing through hole is aligned with the first light supplementing through hole, and the first light supplementing through hole and the double-color transparent cover form a light emitting channel used for enabling light emitted by the interior of the front cylinder assembly to irradiate an object to be shot through the second light supplementing through hole. For the front cylinder assembly, dispensing is not needed, and the whole sealing system adopts a sealing ring for sealing, and he lens is heated in the equipment, and the front cylinder assembly can be suitable for various severe use environments.

Description

technical field [0001] The invention relates to a camera, in particular to a front cylinder assembly, a camera and a monitoring system with the same. Background technique [0002] The ambient temperature for normal use of existing cameras is mostly -30°C to 60°C, mainly because in a limited space, the waterproof structure of the camera is guaranteed by glue sealing, so the nominal use temperature of the glue determines the use environment of the camera , And then limit the camera can only meet the daily use conditions, but can not meet the use of complex and harsh environments. [0003] Therefore, a technical solution is desired to overcome or at least alleviate at least one of the above-mentioned disadvantages of the prior art. Contents of the invention [0004] It is an object of embodiments of the present invention to provide a front barrel assembly that overcomes or at least alleviates at least one of the above-mentioned disadvantages of the prior art. [0005] In or...
