Camera and infrared lamp fixing seat used for the same

Abstract

The invention discloses a camera and an infrared lamp fixing seat used for the same. An infrared lamp fixing seat used for installing an infrared lamp is arranged between window glass of a camera and a camera unit, the camera is provided with a fan used for heat radiation, an air guide channel is arranged on the infrared lamp fixing seat, the air guide channel is communicated with a gap between a lens and the window glass, the fan extracts heat of a mainboard of the camera unit and blows to the window glass in the front through the air guide channel, and the heat of the mainboard of the camera unit is utilized to defog the window glass. Through the arrangement of the air guide channel, a good air channel is formed inside the camera, the air channel penetrates into the gap formed by the lens and the window glass, when air flow flows in the camera, not only a good heat radiation effect can be achieved, but also heat generated on the camera unit can be transported to the gap between the lens and the window glass, thereby achieving an effect of defogging the window glass.

Description

technical field [0001] The invention relates to the technical field of video monitoring devices, in particular to a video camera and an infrared lamp fixing seat used for the video camera. Background technique [0002] With the widespread use of video surveillance, a large number of video surveillance cameras are installed outdoors. For cameras used outdoors, the hot summer environment is the main factor affecting the service life of the cameras. Moreover, during the heavy rain in summer or the sudden drop in temperature in the morning and evening of autumn, the front glass window of the camera is prone to condensation and fogging, resulting in blurred images captured by the camera and affecting the analysis and processing of images. Biggest application challenge. [0003] Such as figure 1 As shown, in the existing technical solutions, a turbofan 8 is generally arranged in the camera, and the core device on the main board 5 of the camera unit conducts heat to the heat diss...

Problems solved by technology

Therefore, this structure also blocks the hot wind blown by the turbofan 8 while blocking the light, that is, there is no wind entering the space between the front end of the lens 4 and the window glass 2, so the effect of defogging cannot be achieved.

[0005] In addition, in this technical solution, the contact between the infrared lamp fixing seat 3 and the housing 1 is at an angle of 90°, and the upper air duct is easy to form a vortex in the corner, which is not conducive to the air circulation and defogging inside the camera

Moreover, the assembly process of installing the diaphragm 32 on the window glass 2 is complicated, requires multiple glue dispensing, the assembly is difficult, and the cost is high.
