This VIVOTEK Automatic Barrier is a motorised boom-gate/barrier arm used to physically control vehicle access into a parking area, estate, business premises or secure site — raising and lowering automatically to let an authorised vehicle through and blocking the roadway when closed. Barriers like this are typically integrated with an access-control system such as a licence-plate-recognition camera, remote control, intercom or card/ticket reader so entry can be automated rather than requiring a guard to manually operate a gate. It's aimed at businesses, estates, complexes and parking operators needing vehicle access control at a boom gate, not a pedestrian door or general security camera.
