A security bollard system with a housing and at least one bollard assembly. The housing has an interior and a top surface with an opening through the top surface into the interior. The bollard assembly is positioned within the housing and includes a bollard. The bollard is rotatably coupled to the interior of the housing and is rotatable between a lowered position and a raised position. When in the lowered position, the bollard is positioned in the interior of the housing and when in the raised position, the bollard extends up through the opening in the top surface of the housing. Each bollard is configured to be moved between the lowered positioned and the raised position manually. Additionally, each bollard has a pivot point about which the bollard rotates that is positioned to balance the bollard about the pivot point and limit torque required to rotate the bollard.
