Description

Waterproof antifog outdoor probe

Technical Field

The utility model relates to a probe field, more specifically say, relate to a waterproof antifog outdoor probe.

Background

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

With the development of society, the demand of people on monitoring outdoor scenes such as parking lots, community management, traffic intersections and the like is increasing day by day, so that the requirement of rapid development in the field of video monitoring on a video monitoring probe is increasing day by day, and the requirements on the definition of video monitoring and the definition of video monitoring which can still be kept high in a severe environment present a very high challenge. The scene of using the probe in practice has some outdoor environment more abominable, meets in rainy day or the great environment of the morning and evening difference in temperature, makes air humidity higher, and the temperature is lower, appears water smoke easily at the lens internal surface and even the comdenstion water appears, can cause the not clear condition of control picture, has just declined the collection quality of video.

Because the long-term in-process of using of probe of making a video recording, the electronic components of the inside can generate heat, leads to the pressure grow of the inside, needs to increase waterproof ventilated membrane and lets out pressure. However, the breathable film is bidirectional, and can exhaust air outwards, external moisture can enter the camera probe, and accordingly defogging is needed to be carried out all the time, and the existing defogging methods include heating defogging, wind-heat defogging, desiccant defogging, antifogging coating defogging and the like. The defogging method of the antifogging coating is to plate an antifogging coating on the surface of the lens, and has the advantages of higher cost, low yield, strict use environment and short effective time at present; the heating defogging method and the air-heating defogging method are more cumbersome and increase the workload of the camera.

In order to solve the problem, the waterproof and antifogging outdoor probe capable of being used stably for a long time is disclosed, moisture is prevented from entering the inside of a lens, water mist and condensate water are prevented from occurring under any severe scene, the balance of internal and external air pressure can be kept under any environment, any additional intelligent control is not needed, and the energy conservation and the reduction of the internal space and the cost of the probe can be achieved.
