Sorts of zone security |

•Secured zones
In this case the transition zones must be secured in 2 directions with a badge reader and it has to be physically impossible to make a transition zone without registration (for example with the help of turnstiles). This allows the system to monitor with certainty which employees are present in which zone.
•Non secured zones
In this case the transition zones are not secured in 2 directions (for example only enter with registration and exit with pushbutton. No physical shield so that at the entrance multiple people can walk through). In this case the system can't follow up with certainty which employees are present in which zone, it can only detect the last registered transition zone.
•Extra possibilities by using zones
The use of zones doesn't only make a logical grouping possible, but also allows the extra functionalities below. These you can all define in the definition screen "Zones".
•Antipassback check:
Only possible with "Secured zones".
In this case the system always checks if the person comes out of the correct zone and if he has access to the new zone. Should this person have passed his badge (from in a zone to outside), or if he's gone outside by circumventing the registration, the system will receive an alarm and access will possibly also be denied.
•Timed antipassback check:
Possible in all security zone modes. In "Non secured zones" it is preferred that the access is composed in a way that only 1 person per registration can physically enter, otherwise this use has little effect.
This control monitors how much time has passed since one has made the same transition zone. In case this is shorter than the one which is set, it can be assumed that the person simply passes his badge at the entrance. Here an alarm is also activated and also access will possibly be denied.
•Control on min./max. persons in zone:
Only possible with "Secured zones".
One can then indicate to zones the minimum number of persons and the maximum number of persons who may be present in a zone. The system will refuse access to the zone or it will refuse leaving the zone when crossing the limits and it will generate an alarm.
•Control on max. time in zone:
Only possible with "Secured zones".
One can define how long a presence in a zone is allowed here. In case an employee should remain present in the zone longer than the maximum time set, an alarm will be generated which will indicate which person remains too long in the relevant zone.
