Physical security is where the site meets the outside world: the approach road, the vehicle checkpoint, the pedestrian entrance and the fence line. ESC designs and delivers the equipment that controls those points — hostile vehicle mitigation, barriers, gates, turnstiles and perimeter detection — with the civil, electrical and control interfaces that make the equipment work as a system rather than a set of products.
Design baselines follow HCIS requirements for regulated facilities and PAS 68 impact ratings for vehicle barriers where the risk assessment calls for them; final selection follows the consultant specification and the authority's requirements. Every barrier, gate and turnstile is integrated with Honeywell access control and video, so an event at the perimeter appears in the security control room with the camera view and the credential record attached.
