Vehicle barriers can be automated or operated manually depending on the location and the client requirement. 

Manually operated barriers are ideal for remote sites, unable to utilise an electrical supply to run an automatic barrier. Access can be granted by security personnel manning entrances. Or, for lower security applications, entrances can be left open during operating hours and then secured out of business hours. 

Automatic barriers can be roll-bar barriers or road blockers, both ideal to secure wide entrance ways. These automated barriers can be utilised in a sally-port configuration to support and facilitate vehicle search by security staff if required.
