Access control is really a system enabling authorities to manage usage of areas and resources in a very given physical facility or computer-based information system. Access control is, in reality, perhaps the most common, everyday phenomenon. For example, a lock over a car door is basically a sort of access control. The PIN with a bank's ATM method is another way of access control. Even nightclub bouncers, waiting in front of the door, are another instance of (perhaps) a more primitive mode of access control. Using an access control mechanism is important when persons seek to secure confidential, important, or sensitive information and equipment.

Vandals are generally opportunists seeking to smash a few windows before they run off to the night. Our window screens make vandals think carefully and take away the appeal of a simple smash and dash. Specialist vandal shields are available that include an aluminium frame fitted having a 2mm perforated steel mesh. These shields offer excellent protection and are a very cost effective option.
