Alternate Identification
Alternate identification for an account may be assigned. The identification is typically a numeric code that operators may use when logging in to the Alarm Notification System.
No two users may have the same alternate ID - each must be unique. The minimum length of the ID is controlled by the Setup.INI property, MinAltIDLength, although a default minimum of four characters will be used if this property has not been set. MinAltIDLength must be added to the [SYSTEM] section.
Trihedral Engineering strongly discourages any reduction in the number of characters required for identification. Any reduction in the number of possible combinations makes it easier for an attacker to compromise your system.
Another possible alternate identification source is a card reader.
At the time of writing, only proximity cards from RF Ideas that support serial port emulation are supported by VTScada.
Readers that use only keyboard emulation are not supported.
