- the protective sheet 91 is stuck on the waterproof film 90 and the adjusting body 40 at the same time.
- the outer part is attached to the adjustment main body 40, and the inner part is attached to the waterproof membrane 90. With such a protective sheet 91, a function of preventing the waterproof film 90 from coming off is obtained.
- the dehumidification adjusting member 14 can be assembled to the surveillance camera with the waterproof film 90 and the protection sheet 91 already attached. It is not necessary to perform waterproofing work such as attaching a sheet after assembly. In this manner, the dehumidification adjusting body 14 alone has the effect of ensuring the waterproofness of the dehumidifying element 42, and the assembling work is simplified.
- the surveillance camera device can be downsized while providing a dehumidification adjustment function.
- the present invention is useful as an outdoor surveillance camera and the like.
