Affected Version: BioStar v2.9.5 or above

 

From v.2.9.5 of BioStar 2, the function "Timed Anti Passback (Timed APB)" has been introduced newly.

Thanks to this new function, the user can set the reset time for anti-passback about the specific door to limit frequent access attempts to that door.

With this feature, once the user authenticates on the entry device, the user cannot re-authenticate on the same entry device or the exit device connected with the entry device until the defined "Reset time" has been gone.



Note that 

To use this new feature, there is no need to use the paid-for versions of the BioStar 2 license since this option can be set directly in the configured door in DOOR, not the Anti-passback Zone of ZONE in BioStar 2.



Expectation effectiveness


Through this function, It can be expected to prevent unauthorized persons from using the authorized person's authentication method to go through the door without permission.

To understand it deeply, please refer to the below example case.


Example Case) If you uses the new function "Timed Anti Passback"

: You can expect that the unauthorized person can't enter the door even though he acquires the authorized person's card due to the specific time set in "Reset Time". In this case, the unauthorized person can't enter the door Until it's past the defined "Reset Time".



Major Features


1. This new function can be applied to either the Entry device only or "the Entry device + the Exit device" based on your needs


2. The event code for "Timed Anti Passback" is supported in the MORNITORING of BioStar 2. 


3. "Timed Anti Passback" DOES NOT support the "Bypass" function unlike when using Anti-passback via ZONE.

4. The input unit is in minutes (min.), with a default setting of 10 minutes. The users can input a time within the range of 0 to 60 minutes. 


Precautions


1. You cannot use this new function simultaneously with the existing "Anti-passback" function. So, you need to be careful about the below 2 exceptional cases when trying to use the "Timed Antipass Back" function.

  • Case 1. In the case that you already use "anti-passback" in ZONE

If you try to set the "Timed Anti Passback" after already configuring the Anti-passback zone, you will see the below error popup.

Plus, on the contrary, when you try to configure the Anti-passback zone as well after already setting the "Timed Anti Passback", you will also see the below error popup.



  • Case 2. In the case that you want to set "anti-passback" in DOOR

If selecting either Soft APB or Hard APB in Anti PassBack, the option "Timed APB" will be inactivated automaticlly. So, if you want to activate "Timed APB", you need to select "None" in the type of Anti PassBack. 


2. Alarm function does not support "Timed Anti Passback" yet but only supports "Anti PassBack" in the configured door.


3. If the door is set up with a wireless door lock, "Timed Anti Passback" CANNOT be used.
