Door Detective and tailgate detection in access control systems

The lack of tailgate detection is one of the biggest threats to any access control system. The lack of tailgate detection is an inherent weakness of access control systems. Unless the access control system is integrated with the right Entrance Technology such as Door Detective, it is almost impossible to either monitor or control the number of unauthorised people that enter or leave through an entrance when a valid access control system card is approved i.e. a potential tailgate situation.

The lack of tailgate detection allows either lazy people who are not bothering to present their access control system cards or people that the access control system should not let in the building.

The lack of tailgate detection is where Door Detective comes in. Door Detective uniquely answers this problem of a lack of tailgate detection at a door controlled by an access control system by creating an infra red field across the door opening to monitor the passage of every individual entering and leaving through that door thereby ensuring tailgate detection. In the event of tailgate detection the Door Detective will provide local and remote indications to alert the individual concerned and security. Additionally the Door Detective can lock doors and trigger cameras to monitor tailgate detection incident and ensure events are recorded for later analysis. Therefore Door Detective ensures only one person gains access through a secured door for each valid card transaction thereby providing tailgate detection at any standard door where an access control system is employed.

Having tailgate detection ensures a more secure over all access control system and Door Detective is the ideal product to provide this tailgate detection. IDL have been manufacturing Door Detective for a number of years and Door Detective is successfully employed in access control system applications as diverse as office buildings, airports, leisure centres, shopping arcades and laboratories. Door Detective can be integrated with all high level access control systems.
