2. OPERATING THE JABLOTRON 100 SYSTEM
The security of access codes, contactless RFID devices and remote controls
A control panel enables each user to be assigned with one 4, 6 or 8-digit code and up to two RFID tags
for system authorization. User authorization is required during each operation via keypad, voice menu,
a computer, web or mobile apps. Code length affects number of possible combinations and therefore
code security.
The number of code combinations depends on the confi guration:
Control panel
parameters
Using
„Code with a prefi x"
„Code with a prefi x"
and „Duress access
control" both disabled
„Code with a prefi x"
disabled; „Duress access
control" enabled
Using only an RFID
card with a range of 14
characters (6 constant + 8
variable)
„Code with a prefi x" and
„Card confi rmation with
a code" both enabled
„Code with a prefi x"
disabled; „Card con-
fi rmation with a code"
enabled
Ways to improve protection against guessing the valid code:
a
Using a code with more digits (6 or 8-digit codes)
a
More advanced types of authorization, such as "Card confi rmation with a code"
or "Double authorization".
