Who knows that network security audit equipment should be installed in hotels in Dongguan? Which one should I pack?

To put it simply, network security audit equipment can detect and record online behaviors, including internet access restrictions, internet blacklists and so on. You can also record QQ chat content, which is not used by ordinary families and is mostly used in hotels and Internet cafes. If you are from a hotel! The Public Security Bureau has issued a notice document, and all hotels and guesthouses that provide Internet access services should install it. I personally recommend Ren Zixing because I used it well before.
