Well, there is no password tool to allow you automatically generate a security code on Internet. You have to copy the Start Time and Device Serial Number and then submit to Hikvision technical support team, the team will run the password tool and generate a security code according to the date/time and serial code info.
Enter your serial number and specify the device ID. Do a right click on Device ID and copy the device ID. You can choose between your computer´s device id or the device id from your network card. Both enable the generation of a unique activation code. 2b1af7f3a8
