Perimeter protection refers to the security measures taken to secure the outer perimeter of a facility or plant. Perimeter protection is a key part of the overall security strategy, especially in sensitive areas such as industrial facilities, military installations or critical infrastructure. This includes the installation of security systems such as surveillance cameras, motion sensors or other detectors and the implementation of additional security measures such as the installation of robots along perimeter zones that can patrol autonomously and communicate with central monitoring systems. The aim is to detect unauthorised access, trigger alarms and inform security forces or automated systems to respond to potential threats.
