Perimeter security could be as simple as natural barriers like mountains, hills, and tree lines. Today, more advanced chain-link fences, concrete walls, and restrictive gates that require authorized credentials to pass have become the norm. Sophisticated technologies that are meant to keep intruders out and prevent access to certain protected areas are more common in today’s perimeter security world. Contained within those perimeters and protected gates – whether by natural barriers or more technologically advanced fences, walls, and gates – are buildings, complexes, and construction areas.
