Where can I buy a password cabinet with a long history in Tianjin Optoelectronics? What about that function? It is said to be used by the secret forces. Is it qualified?

Security units generally need the authentication of the Secrecy Bureau, which can be found on the relevant website of the Security Evaluation Center of the Confidential Information System of the State Secrecy Bureau.

At present, Bao Guo in Guangzhou, Jincheng in Shenzhen and Kerong in Shenzhen (Dongfang Shibang) I know have all passed the certification of the State Secrecy Bureau. More manufacturers can search directly on the website of the evaluation center. If the brand you are asking is qualified, it is recommended to go directly to the relevant website.

There is only one safety cabinet certification of "Tianjin Optoelectronic Communication Technology Co., Ltd." in Tianjin. You need to identify whether the "Tianjin Optoelectronic Jiujiu" you mentioned is one.

As for the purchase, you can contact the manufacturer directly. Some manufacturers do not have local service points and will negotiate remotely. Some manufacturers have local service points and will provide you with the contact information of local business personnel or agents.
