Abstract: The present invention includes: an identification code generation unit that generates, from information of a company code including a first code that uniquely identifies a management target in a part of a company in the part of the company and a second code that identifies the part of the company, an identification code including a history of the management target; a hash processing unit that hashes the identification code generated by the identification code generation unit according to a hash function and converts the hashed identification code into a meaningless code; and a reference code generation unit that generates a reference code unified for the entire company based on the meaningless code converted by the hash processing unit.

Abstract: An indoor camera includes: an image capturing unit; a pan mechanism configured to drive a pan motor to rotate the image capturing unit around a vertical axis; a motor holder housing the pan mechanism and having a contact surface parallel to a horizontal axis on a bottom surface; a suction cup having an internal space and formed of an elastic member, the suction cup having upper and lower openings in upper and lower portions of the internal space, respectively; and a suction cup holder fixed to the suction cup and configured to support a load of a main mechanism portion housing the image capturing unit and the pan mechanism. The lower opening is closed by an installation surface on which the suction cup is installed. The upper opening is configured to seal the internal space by supporting the contact surface by the load of the main mechanism portion.
