Protecting property and premises Intrusion and access control have become essential priorities for securing buildings and today the focus is on technological convergence and the upgradability of our solutions. Technological convergence relates to the compatibility of components: the end users become the masters of their own equipment which can be easily upgraded as and when required. However, to ensure optimal security this technology needs to adapt to the constraints and specificities of each installation. It is therefore vital that these systems benefit from complete continuity of service.
