What is the optimum temperature and humidity for the camera moistureproof box?

Reference for humidity conditions of goods storage: books, antiques, paper money, ancient books, fax paper, copy paper 60% ~ 55% cameras, video cameras, lenses, microscopes, magnifying glasses, telescopes, magnetic tapes, magnetic disks, recording tapes, films, musical instruments, stamps, furs 55% ~ 45% precision hardware molds, measuring instruments, electronic parts and metals. The following are mildew conditions: 1), humidity: when the relative humidity of the environment is greater than 60%, mold can grow. When the RH is higher than 65%, the growth is accelerated, and when the humidity reaches RH80-95%, it is an environment with high incidence of mold. 2) Temperature: The mycelia of mold can grow at the ambient temperature above 8 degrees, and the growth is accelerated above 65438 02 degrees. When the temperature is higher than 10 degree and the humidity is higher than 60%, mold will do harm to articles. When the temperature is 20-30 degrees and the humidity is 75-95%, mold can grow explosively. 3) Nutrients: molds need few nutrients. Carbon, nitrogen, potassium, phosphorus, sulfur and magnesium are essential nutrients for molds, and molds can also absorb all basic elements from inorganic salts. When the articles contain the nutrients needed by the above molds and the temperature and humidity of the environment are suitable for spore development, molds can grow. Therefore, it is concluded that the temperature at room temperature is about 25 degrees and the humidity is below 55%. Generally, room temperature plus desiccant is enough, so don't worry too much.
