Description

Technical Field

[0001] The present application relates to the field of surveillance cameras, and in particular to a defog structure of a surveillance camera. Background Art

[0002] A surveillance camera is a device that can monitor the captured images in real time. It can help us achieve functions such as remote monitoring and security prevention. A surveillance camera is usually composed of a lens, an image sensor, a digital signal processor, a memory, and a transmission medium. Its working principle is that when the surveillance camera is in use, the camera is installed on the surface of the building with the help of a fixed bracket. The camera collects light and reflects it onto the image sensor. The image sensor converts the optical signal into an electrical signal, and the digital signal processor converts the electrical signal into a digital signal. The memory stores these digital signals and finally transmits the signal to the terminal device through the transmission medium for us to view and record.

[0003] With respect to the above-mentioned related technologies, the inventors believe that when the temperature of a conventional camera changes too quickly or is in a place with high humidity, water mist is easily generated on the surface of the camera, which can easily cause the images taken by the camera to be blurred, thus affecting the use of the camera.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
