Door Propping

It is often done to facilitate access and convenience; propping doors unintentionally permits unauthorised access. Systems for controlling access to can detect the propped doors, and then alert personnel effectively tackle this issue.

Forced Entry through Levering Doors

Doors that open by levering with tools such as screwdrivers or crowbars is not uncommon. Modern access control devices that incorporate alarm triggers and monitored forced doors are extremely efficient in detecting these attacks, in spite of their risk of false alarms, or databases problems.
