G4S Infrastructure

Recognising the need for enhanced security features for these projects G4S have developed the SymmetryCNI system which has now been approved by the Centre for the Protection of National Infrastructure (CPNI) to their Automatic Access Control Systems (AACS) standard and is included within the CPNI Catalogue of Security Equipment (CSE) approved for UK Government use.

Threat Level Management

One of the many features of SymmetryCNI  is Threat Level Manager enabling you to change a building's security at the click of a button. You may want to enhance security when there is a greater threat of criminal or terrorist activities, or during times of limited occupancy such as holiday or site shutdown periods, and lower it at other times. Five threat levels are available, each of which you can customize to provide a different level of security. Changing the threat level can determine which cards have access, which areas they can access and the scheduled and trigger commands that can operate.
