Vehicle Barriers
Vehicle barriers, or security bollards, are a necessary part of any effective car-focused security apparatus. It is the most effective method of denying vehicle entry to a specific place. They come in various models, all of which are designed for the purpose of stopping vehicles, but there are some with added functions. For instance, having retractable bollards, so that an area and pathway can be opened up when you choose, can be beneficial. This typically happens through one of two mechanisms. The first type is where they can lay down on the ground when you want them to: Typically these are smaller, but more convenient in situations where they are regularly raised and taken down. The other type is the typically more heavy duty model, which can retract downinto the ground, and then shoot up. This mechanism offers greater security, but it can also be less time efficient.
