About this video
Bollards are physical security barriers positioned to block vehicle access while leaving pedestrian pathways open. Their key advantage over permanent barriers is flexibility — retractable models can be raised or lowered on demand, allowing authorized vehicle entry when needed and restricting it when not. This makes them well-suited for locations where access requirements change throughout the day or based on security conditions.
When a bollard is in the raised position, it anchors deeply into the ground, giving it the structural integrity to withstand a direct vehicle strike. This depth is what distinguishes a bollard from lighter surface-mounted barriers — the force of an impact is distributed into the ground rather than absorbed by the barrier alone. For security planners, bollards represent a scalable, durable solution for perimeter control in both high-traffic public areas and restricted access environments.
