The automatic bollard is a mechanical device, usually used in places of traffic management or security control. It consists of a column embedded in the ground which can be controlled by an electric motor or hydraulic system to raise and lower the column. This type of equipment is often used to control vehicle access, for example at the entrance and exit of car parks, and in areas where traffic needs to be restricted, such as specific vehicle permit areas or security zones.

Automatic bollards are very common in locations where the flow of vehicles needs to be controlled or access to specific areas restricted. It can be integrated with other systems such as vehicle identification systems, access control systems or traffic signals to automate vehicle access control. When a vehicle is authorised to enter or leave an area, the automatic bollards are raised or lowered accordingly, ensuring that only authorised vehicles can pass.

4, visual monitoring: the access control system can provide real-time monitoring and alarm functions when linked to the automatic bollards. For example, when an unauthorised vehicle attempts to enter, the system can immediately sound an alarm or trigger the appropriate security measures to ensure the safety of the plot or villa area.
