The whole perimeter of the area is secured with a fence. It has a deterrent effect: it shows that access is reserved for authorised persons.
Sliding gates, swing gates, turnstiles, and barriers provide necessary access control for the staff and other authorised persons.
The football field is a zone with increased security risk. The choice here falls on a fence with a delaying effect in order to protect the players and the field from unauthorised access. The delay factor (= the time during which the fence withstands unauthorised persons) is defined in relation to the time during which the security service or the police must react.
Turnstiles ensure controlled access of staff and access of public authorities allowed to use the facilities. They can be equipped, for example, with a card reader so that it is clear who is present in the facility at all times.
Just like at other sports events, emotions at football arenas can easily reach the boiling point. It is important to keep the flow of supporters and vehicles strictly segregated. This applies to the road from the car park to the field and back again.
Turnstiles are used for regulating and controlling supporters, and automated obstacles and gates are used in multi-storey car parks to control vehicle access.
