Access control is a fundamental security measure for buildings. Special opening and closing solutions are required for locations with high security requirements in particular. Access control may also contain a single-access entry control system to control the flow of people. Known systems include turnstiles, safety locks and sensor barriers. In combination with a barrier, the system is set up to ensure that only one person can pass through at once.

Ensuring windows and doors are secure is vital for protecting buildings. Glazed balcony and terrace doors are classic weak 
spots. Older makes are also easy to lever open. Always close and lock all windows and doors when you leave the building. Windows left ajar are open windows. In this case, intruders can break into the building in less than 30 seconds. There are even more ways to secure your windows and doors: Detectors report unwanted access to the alarm system mechanically, electronically or magnetically. Doors, windows and garage doors, etc. can also be easily monitored using CCTV.
