Keyscan Inc. has added a tailgating detection system (TDS) to its product solutions for access control. The TDS system uses a curtain of 32 IR sensors to determine if more than one person has passed through to a secure area on a single valid card read. The TDS triggers an audible alarm, alerting anyone in the area of the security breach, as well as activating an alarm relay that can be interfaced with an access control system. For high-security areas such as server rooms, man traps, clean rooms, and other security sensitive areas, the TDS adds an additional layer of protection against unauthorized access. Each system comes with a Keyscan reader that can be installed within the unit.
