[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the scheme of this application:

[0018] 1. The temperature and humidity inside and outside the camera are collected in real time by temperature control probes inside and outside the camera, and then transmitted back to the control box (an external device). Based on the temperature and humidity differences inside and outside the camera, the control box determines whether hot air or cold air is input into the first pneumatic joint. The second pneumatic joint is the return air port. Both the first and second pneumatic joints are connected to the external pneumatic device, effectively preventing condensation on the camera lens and improving the clarity of the captured image.
