What is tailgating, and how can it be prevented in security revolving doors and speed gates?
Tailgating in high-security revolving doors
Tailgating in security revolving doors occurs when an unauthorised individual attempts to gain access to a secure area by following closely behind an authorized user. This is a common security breach.
Tailgating may sometimes appear harmless, such as when someone “helps” another person enter because they forgot their access card. However, it can also involve an unknown individual intentionally trying to sneak in behind an authorised user.
A reliable security revolving door detects and prevents tailgating, regardless of the access control system in place.
